Uh, no.
10 feet = 1 decafoot
100 centiyards = 1 yard
1x10^18 attoacres = 1 acre
Uh, no.
10 feet = 1 decafoot
100 centiyards = 1 yard
1x10^18 attoacres = 1 acre
It's obvious that there's 1760 yards in a mile.
There's 22 yards in a chain, which we can all remember because of the 22 yard line in rugby.
There are 10 chains in a furlong, which fans of metric can't complain about.
There are 8 furlongs in a mile, just like there are 8 pints in a gallon.
And 22x10x8 = 11x10x16 and 11 is easy to multiply by in your head, so it's really very simple to get to 1760.

this but unironically.
Congratulations, you're brainwashed.
Do americans actually do math with imperial system at school? That must be a nightmare and have conversion errors between units.
This is a common misconception. Americans can't do math and don't learn anything at school
Kinda.... The classes "teach" imperial but guns/bullets are metric
So the most American things in America are using the least American measurement system?
some of the popular ones are measured in metric, but there's plenty that are not.
https://en.wikipedia.org/wiki/Caliber#Metric_and_US_customary
It's a pretty heavy mix, many of the most popular rounds are also referenced by their metric size but they're not usually 'useful' sizes in either standard or metric.
For example:
There's almost never a need to involve units outside of science which typically is metric anyway. Also most of these units aren't really ever converted between, no one gives a measurement as 1 mile 300 yards 2 feet 6 inches.
no one gives a measurement as 1 mile 300 yards 2 feet 6 inches.
When this topic came up yet another time previously, USian engineers proudly chimed in saying that their software accepts any kinds of units and converts between them as needed, so they put in US units without bothering about whether metric units are used elsewhere in the project. Ergo, someone does in fact give measurements like in your example.
I have very occasionally seen measurements given in yd + in or yd. + dec ft. I have never once seen measurements given in any of yd + ft + in, mi + yd, mi + yd + ft and definitely never in mi + yd + ft + in. That would be like giving a measurement in km + dm + cm + mm, there's just no reason to do it. Any cad software I've ever used is capable of handling mixed units because it's trivial to implement, but I would be willing to bet it's one of the most underutilized features.
It only seems ridiculous because you forgot some intermediates: 5.5 yards = 1 rod, 4 rods = 1 chain, 10 chain = 1 furlong, and 8 furlong = 1 mile. So just gotta remember 12, 3, 5.5, 4, 10, 8. Super simple.
Rod? Chain? What is this bdsm?
Worse, its the imperial units "system"
No safeword, no lube
This explanation is fucking gold
You mean US Customary
No, it's not "Imperial units" and hasn't been for a long time. It's US Customary units. There are differences between the two systems. If your going to troll, get it right.
If you can't, go back to your troll cave and cuddle your delicious stinky cheeses!
Links and chains brings me back to my old drafting days. 10 square chains are 1 acre. 80 chains is a mile.
one thing i enjoy way more than i should is use units that are technically correct, but no one uses them like ever.
like megagrams instead of metric tonnes.
or 1 dekameter instead of 10 meters.
I measure battery capacity and electricity consumption in J/kJ/MJ, as intended. None of that kWh bullshit.
It also makes for fun comparison with energy value of foods.
Energy is energy, after all.
I only use metric when it's in forms nobody else uses or recognizes at a glance because I need to be difficult. Decimeter is perfect for like, height of a person, for example. Why do they use CM?
Why do they use CM?
Precision. "17dm" can be anything between 16.5dm or 17.5dm.
You could of course say "I'm 17.5dm tall", but at this point "I'm 175cm tall" is shorter (no dot).
That said I've seen plenty people measuring height in metres and then centimetres. Usually something like "I'm one [metre] and 75 [centimetres] tall".
decimeters is perfectly fine. basically all volume calculations boil down to dm³ as 1 dm³ = 1L
1,000 kilometres = 1 megametre
0.01 Petameters
1 megametre equals: 0.001 gigametres 0.000001 terametres 0.000000001 petametres
Meanwhile, 1 megameter is the same as: 0.001 gigameters 0.000001 terameters 0.000000001 petameters
True, I did not mean my comment as a real conversion tho.
Now, speaking of megameters 😈 I'm pretty sure you can tell me which prefix corresponds to this from the top of your head. One of my favorite ones ever alongside its negative.
n-meter = 1,000,000,000,000,000,000,000,000 megameters.
Sir, this is a Wendy's, we measure in common units around here...
1 acre
UK 4,046.85642 m²
US 4,046.87261 m²
1 acre (us international acre)= 0.999996 acres(us survey acres).
Even inside the US they use two different measures for acre.
At least the US temperature scale is safe from ridicule, as Lord Fahrenheit was German/Polish.
Edit: /s, obviously.
My contrarian brain:
I've said it on this platform before: I will build furniture in inches until my hands can't hold a chisel anymore. The inch system arose around the needs of carpentry and woodworking, it works in base 12, which is outright superior to base 10, especially when you divide by 3 and 4 more often than by 5.
Also, the closest tape measure I have to hand is my 5m metric tape. I build things in metric, just...not furniture.
Wow, base 12, I never thought of thas! You halve it, quarter it, and third it, and still end up with clean integers.
Yeah; you'll often find boards in America milled to 3/4" or 1 1/2". Those are 1/16th or 1/8th of a foot. A lot of boards used in furniture are 3/4" thick. Half of 3/4 is 3/8, a third of 3/4 is 1/4. It solves the problems we need to solve, and the metric woodworkers start sounding how teaspoon/cup/quart cooks do.
A dozenal metric system would work as well as the decimal metric system, as long as everything else was base-12:
| in base 12 | in base 10 |
|---|---|
| 1m'm = 10⁻³m = 0.001m | 1m'm = 12⁻³m = 1/1728m |
| 1c'm = 10⁻²m = 0.01m | 1c'm = 12⁻²m = 1/144m |
| 1m = 1m | 1m = 1m |
| 1k'm = 10³m = 1000m | 1k'm = 12³m = 1728m |
Since we're at this might as well say the day has 10₁₂k's = 20736₁₀s. Each k's is exactly two of our current hours, and each "new second" is roughly two four of our current seconds. Enough of this Sumerian mixed base already!
I'm a carpenter as well, and I hear what you're saying, but also my coworkers and I were just talking yesterday about how much better metric is 😅 Every base-12 advantage is weakened by the fact that I'm constantly expected to do fractions. Everything in metric is a whole number and it's so hot. Love it when I get an actual number to build something to, instead of a math problem.
If you've ever ordered lumber from a Canadian company, you know how much easier it is to calculate and order in metric units vs. board-feet. I feel bad for their sales reps who have to deal with us Yankeestanis.
Also, all the really nice chisels and hand tools from Japan and Europe are already in metric.
What do you do when a piece you're cutting isnt exactly a foot, say, 11 or 13 inches? I know nothing about woodworking, but I'm assuming there isnt a unified standard to make everything match to the nearest whole foot, so then this whole base 12 thing goes out the window, or am I missing something here?
Basically there is a conflict going on amongst the woodworkers of the world between those who think clearer in decimals, and those who think clearer in fractions. The fraction folks will tend to prefer standard units, the decimal thinkers will tend to prefer metric.
What's interesting to me is: you only ever hear Americans complaining about metric, but you never hear woodworkers from Europe or Japan talk about the advantages of standard units... while the Europeans and Japanese are also pumping out generally much higher-quality woodworking than most folks in the USA are. You can probably tell which I prefer lol
My take is, if the standard units were really that much better, I think Japanese and French folks would be using them, because their cultures care a looot more about fine woodworking than the USA's culture does.
You look at your tape measure, at the number 11 or 13 as appropriate, put a mark there, then take it to the saw and cut it.
I meant, for cutting in thirds and quarters. An exact foot you can cut at 3 and 4 inches, but if a board is 13 inches, divide that by 3 and you have to cut at... 4.3333333 inches?
Same thing you do for cutting 13cm into thirds: make one third a bit fat. Go 4 1/4, 4 1/4 and 4 1/2". Or construct it.
That's not a problem I face in the wood shop a lot though. A more practical problem: We tend to mill boards to 3/4" in thickness. To do a half-lap joint, you need to cut away half the thickness of each board and then lap them over each other, you can set your depth to 3/8" and you're there. If I'm going to do a bridle joint or a mortise and tenon, a third of 3/4" is 1/4". Show me a third of 19mm on a metric ruler. I'll show you where it is: 6, 6, and 7mm.
I've setup a software that generate quotes, sales invoice and production order for a windows and door company. The sales person enter the dimensions and option of the window and it automatically calculate the price, the exact amount material, deduct it from the inventory and generate the cutting and assembly instruction.
They were all working with fractional inches. I've started setting up the system using inches and it was a NIGHTMARE ! I quickly decided to convert everything on metric in the back end and to do all the calculations on that and I reconvert it in inches at the end.
Now most of the workers are using metric because it just make more sense.
I kinda want a hexadecimal version of the metric system.
In hex:
10 mm = 1cm
100cm = 1m
1000m = 1km
1km - 1m = FFFm = 0.FFFkm
Still works fine.
Wouldn't it be
Edit: nvm I see what you mean, but then we should change the units too, to something like xmm, xcm etc.
Measurement system doesn't have anything to do with numerical base. You can use any base with any system.
16m = Fm
which is pretty ass if you ask me
The biggest problem is that if you're still using numbers that are designed for base 10 it'll look messy no matter how you cut it. Hexadecimal is an approximation.
You've been hit by...

A smooth metric system
Americans choose to meassure thier dicks with the thumb of a british king instead of using meters... or GIGAmeters... there are no correct awnsers, right?
0.0000000003448 GIGAmeters just doesn't sound that impressive...
3,5 10^-10^ Gm
Also, notice that ypu can round it up a bit...
And, who meassures his dick... you just need an honest aproximation.
Exemple: "my dick? You mean from the root? I think it's just a fraction of a gigameter.." which is a 100% honest and humble response.
Edit: one can also use astronomic units.... 1 AU =~ 150 Gm
Whats funny is the oil and gas industry has orders of magnitude worse units. So much so, I would say the imperial system is scared of it.
I mean the yard and pound have been defined by metric for a long time so it's really just an indirect metric system so the USs feelings don't get hurt.
22 yds to a chain, 10 chains to a furlong, 8 furlongs to a mile.
The one thing metric screws up is file size.
A gigabyte is 1000 megabytes or 1,000,000 kilobytes or 1,000,000,000 bytes.
A gibibyte is 1024 mebibyte or 1,048,576 kibibyte or 1,073,741,824 bytes, because it needs to go by increments of a power of 2.
This would be fine except gigabyte also means gibibyte. So if a file claims to be N GBs, I don't know if it actually means metric GBs or GiBs.
That is not exactly metric 's fault though. It's whoever made the decision to portray stuff as such in operating systems
I got a question about hard drive sizes on a math test 15 years ago. Was super frustrating, since I didn't know wether or not the person who wrote the test, knew the difference.
