Summary
Enter a Mach number and instantly get the equivalent speed in meters per second, km/h, and mph.
How it works
- Enter a Mach number in the input field (e.g. 1, 2.5, 0.85).
- The converter multiplies by 343 m/s — the speed of sound at sea level (15°C, dry air).
- Results appear instantly in m/s, km/h, and mph.
- Use the common presets (Mach 1–5) for quick reference.
- Click "Copy" next to any result to copy that value to your clipboard.
Use cases
- Convert fighter jet or missile speeds from Mach to metric units.
- Understand supersonic and hypersonic speed classifications.
- Calculate m/s for physics or engineering coursework.
- Compare aircraft speeds during aviation study or research.
- Estimate travel time for supersonic vehicles at a given Mach number.
- Cross-check wind tunnel or CFD simulation speed parameters.
