Knots — Maritime and Aviation Speed
One knot = 1.852 km/h = 1.151 mph. Knots are used in maritime navigation and aviation worldwide. If you see a weather forecast with wind speed in knots, multiply by 1.852 to get km/h or by 1.151 to get mph.
The unit converter above supports knots in the Speed category alongside km/h and mph.
Treadmill Speeds — MPH vs KM/H
US treadmills display speed in mph. European and international treadmills use km/h. If your gym treadmill shows a setting in the wrong unit:
- 5 km/h = 3.1 mph (brisk walk)
- 8 km/h = 5.0 mph (easy jog)
- 10 km/h = 6.2 mph (moderate run)
- 12 km/h = 7.5 mph (faster running)
- 16 km/h = 9.9 mph (fast running)
