公式
## How to Convert Mach Number to Speed ### Formula **Speed (mph) = Mach × 767.269** **Speed (km/h) = Mach × 1234.8** Mach 1 is the speed of sound at sea level and 15 degrees Celsius, approximately 343 meters per second (767.269 mph or 1234.8 km/h). Actual speed of sound varies with temperature and altitude.
计算示例
Convert Mach 2 to mph and km/h.
- 01mph = 2 × 767.269 = 1534.54 mph
- 02km/h = 2 × 1234.8 = 2469.60 km/h
- 03m/s = 2 × 343 = 686.00 m/s
常见问题
What is Mach 1?
Mach 1 is the speed of sound, approximately 767 mph (1235 km/h) at sea level and 15 degrees Celsius.
Does the speed of sound change with altitude?
Yes, the speed of sound decreases with altitude because temperature drops. At 35,000 ft, Mach 1 is roughly 660 mph.
What is supersonic speed?
Any speed above Mach 1 is supersonic. Speeds above Mach 5 are called hypersonic.
