Thank you. I was looking at it thinking, "but 100m is only 10% of the other distance".

BTW for any curious non-muricans, miles is abbreviated "mi" so it doesn't get confused with meters. The only slight exception is when you are dealing with transportation, where none of the units are abbreviated properly:

• miles per hour = "mph" (should be mi/hr)
• miles per gallon = "mpg" (should be mi/gal)
