How to convert mach (sea level)s to knots
Multiply the number of mach (sea level)s by 661.470842333 to get knots.
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.
Knot: One nautical mile per hour — the standard at sea and in aviation.
