How to convert Knots to Speed of Sound Air
Multiply the knots value by 0.00149984: 1 kn = 0.00149984 Mach 1. Going the other way, 1 Mach 1 = 666.739 kn, so divide by 0.00149984 or use the Speed of Sound Air to Knots converter.
About these units
Knots (kn)
A knot is one nautical mile per hour, exactly 1.852 km/h or about 1.151 mph. Ship and aircraft speeds and wind speeds at sea are given in knots.
Speed of Sound Air (Mach 1)
The speed of sound in air at 20 °C is about 343 meters per second (1,235 km/h). It falls as the air gets colder, so the exact value depends on conditions.
