How the Knots to MPH Calculator Works
A knot is one nautical mile per hour, the speed unit used in aviation and at sea. Because a nautical mile (6,076 ft) is longer than a statute mile (5,280 ft), a knot is a bit faster than a mile per hour — exactly 1.15078 mph. This calculator converts knots to miles per hour, and also to km/h, metres per second and feet per minute.
So 100 knots is about 115 mph. To go the other way, divide mph by 1.15078.
mph = knots × 1.15078
Frequently Asked Questions
What is a knot?
One nautical mile per hour. It’s the standard speed unit for aircraft and ships.
How many mph is 100 knots?
About 115 mph — 100 × 1.15078.
Why are knots faster than mph?
A nautical mile is longer than a statute mile, so covering one per hour is a greater speed — about 15% more.
