About both units

From

Mach

Mach is the ratio of an object's speed to the local speed of sound. Mach 1 at sea level in standard conditions = 1225 km/h (340.29 m/s). Supersonic starts at Mach 1; hypersonic at Mach 5. The Concorde cruised at Mach 2.04; the X-15 reached Mach 6.7.

Real-world: Concorde: Mach 2.04. F-16 fighter: Mach 2. SR-71 Blackbird: Mach 3.3. Space re-entry: Mach 25+.

Mile per Hour

mph

Miles per hour (mph) is the standard road-speed unit in the US, UK and a few other countries. US highways typically 65–75 mph; UK motorways 70 mph. US weather reports wind speed in mph, while meteorologists also use knots.

Real-world: US interstate: 70 mph typical. UK motorway: 70 mph limit. Cycling pro speed: 25 mph. Tornado winds: 110+ mph.

Tips & common mistakes

Quick tips

Mach 1 = ~1225 km/h at sea level, standard conditions.
Local speed of sound decreases with altitude (colder air) — true Mach value varies.
Mach 0.8+ is "transonic"; Mach 1+ supersonic; Mach 5+ hypersonic.

Avoid these

Assuming Mach 1 is a fixed speed — depends on altitude and temperature.
Multiplying Mach values as simple ratios across altitudes.
Using Mach for subsonic everyday speeds — not practical.
