How to convert Miles per Hour to Knots
Speed units depend on context: road signs use km/h or mph, physics uses meters per second, and ships and aircraft use knots. Converting between them is essential for travel, sport, and science.
Everything converts through meters per second. One km/h is exactly 1/3.6 m/s, one mph is exactly 0.44704 m/s, and one knot is one nautical mile per hour — about 0.5144 m/s.
Formula
mph × 0.868976242 = kn
Multiply your miles per hour value by 0.868976242 to get knots. For the reverse, divide by the same factor.
