Convert knots to mach (sea level)s
1 kn = 0.00151178243394 Ma — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.

How to convert knots to mach (sea level)s
Multiply the number of knots by 0.00151178243394 to get mach (sea level)s.
Knot: One nautical mile per hour — the standard at sea and in aviation.
Mach (sea level): Speed of sound in the ISA standard atmosphere at sea level, 15 °C. Falls with altitude, so Mach is not a fixed speed.
