Frequently Asked Questions
How do I convert between two specific units?
Enter your value, select the unit it's in from the "From unit" dropdown, and read the result off the row for the unit you want. Clicking a row makes that unit the new input, so you can chain conversions.
How many feet are in a meter?
1 meter = 3.28084 ft β 39.37 inches. Going the other way, 1 foot = 0.3048 m exactly.
What is a nautical mile?
A nautical mile is exactly 1,852 m, defined for sea and air navigation; it corresponds to one minute of latitude. 1 nmi β 1.1508 land miles.
Are the conversion factors exact?
Yes. Imperial units are defined from the international yard (1 yd = 0.9144 m exactly), so 1 in = 25.4 mm, 1 ft = 0.3048 m, and 1 mi = 1,609.344 m are all exact. Displayed results are rounded for readability.
