Short background on the units used in this conversion.
Mach number compares speed to the local speed of sound. This converter uses ~340.29 m/s at sea level near standard conditions — actual Mach varies with altitude and temperature.
Mach describes supersonic aircraft performance, aerospace engineering, and high-speed wind-tunnel tests.
Miles per hour measure how many statute miles are traveled in one hour — 1 mph equals 0.44704 m/s.
Miles per hour dominate US and UK road speed limits, vehicle gauges, and aviation wind reports.
