...because the shape of the water bottle isn't uniform either. Part of my new year's resolution is to drink 4 liters of water per day, so I spend a lot of time looking at those lines. Edit: 4 liters is a lot, but appropriate for my size and activity level. Without conscious consideration I don't drink enough water. It looks blue because the bottle is blue.
Your bottle isn't a uniform shape. There's internal volume missing where the handle is, requiring greater vertical length to equate to the same volume elsewhere
It's not perfectly cylindrical, the handle cuts out volume (which makes sense).
Neat.
Although... Why 4 L of water? There has been a persistent gym-trainer recommendation for folk to drink the whole recommended daily allowance of water as a distinct supplement, even though most other foods and drink supply adequate hydration on their own.
Water is great as a snack-alternative for caloric reduction, however, not to mention it's use in thermal regulation. My understanding is just that they "you're dehydrated unless your pee is clear" folks are operating outside the mean of medical advice.
The marks on the.bottle are definitely interesting, though.
They aren’t?
One is 500 ml increments the other 16oz increments.
Aside from the handle area, the 500 looks less than half way to 1000.
I would fill it to 500, pour that into another container, fill it to 500 again, pour the first amount back and see if it reaches 1000.
