Frequently Asked Questions
1 Knot is exactly 1 nautical mile per hour, which is approximately 1.15078 miles per hour (MPH) or 1.852 kilometers per hour (KPH).
At sea level with a temperature of 15°C (59°F), Mach 1 is approximately 1,225 km/h (761 mph) or 340.3 m/s.
To convert Kilometers per Hour to Miles per Hour, multiply the KPH value by 0.621371.
