Speed conversion is useful for driving (km/h to mph), aviation (knots), and sports (meters per second). Most countries use km/h; the US and UK use mph. Nautical miles per hour (knots) are used in aviation and maritime. 100 km/h ≈ 62 mph, 1 knot ≈ 1.852 km/h. Enter any value and get the result in real time.
Common conversions: 1 km/h = 0.621 mph, 1 mph = 1.609 km/h, 1 knot = 1.852 km/h. Use the converter above for any value. Driving: speed limits, car specs. Aviation: flight speed, wind. Maritime: boat speed. Sports: running, cycling. Science: velocity, physics. Swap units to convert in reverse. Copy the result with one click. Supported units: km/h, mph, m/s, knots, ft/s. Regulatory manuals sometimes cite meters per second alongside knots—once you lock one value here, you can paste consistent numbers into maintenance logs or incident briefings without juggling spreadsheets offline. E-scooter share programs and cycling power meters often export m/s internally—convert those exports before sharing social pace screenshots.
