What does Mach (20°C, 1 atm) represent?

Mach (20°C, 1 atm) is a dimensionless speed ratio comparing an object's speed to the speed of sound in dry air at 20°C and 1 atm pressure.

Why use Knot (UK) for speed measurements?

Knot (UK) denotes speed in nautical miles per hour, commonly used in UK maritime and aviation practices for navigation and weather reports.

Can this converter be used outside the standard atmospheric conditions?

This conversion is based on Mach values at 20°C and 1 atm; using it outside these conditions may reduce accuracy.
