No, nautical miles are different units used in marine and air navigation. One nautical mile equals about 1.852 kilometers, which is longer than a standard mile. The factor 0.621371 applies only to converting kilometers to standard (statute) miles.
Why do some sources give slightly different mile values for kilometers?
Differences arise because of rounding or using approximate conversion factors. The exact factor is 0.621371192237, but many tools round it to fewer decimals. This causes small variations in the converted result, but they usually don’t affect everyday calculations noticeably.
Is converting kilometers to miles reversible without loss?
Converting kilometers to miles and back can introduce tiny errors due to rounding. Multiplying by 0.621371 and then dividing by 0.621371 won’t always return exactly the original number because decimal places get cut off. For precise work, use high-precision values and careful rounding.
