Speed conversions are commonly needed when traveling internationally, following weather reports, or working in science and engineering. The United States uses miles per hour, while most of the world uses kilometers per hour. Meters per second is the SI standard, and knots are used in aviation and maritime contexts.
Multiply the speed in miles per hour by 1.60934. For example, 60 mph = 96.56 km/h. A quick estimate is to multiply by 1.6. This is useful when driving in countries that use the metric system.
A knot is one nautical mile per hour, equal to approximately 1.151 mph or 1.852 km/h. Knots are used in maritime and aviation navigation because they relate directly to degrees of latitude.
Mach 1 is the speed of sound, approximately 767 mph or 1,235 km/h at sea level and 68°F (20°C). The exact speed varies with altitude and temperature since sound travels differently through air of different densities.
