About converting Mach to Knot

Converting Mach to Knot is a common speed conversion. One mach (M) equals 661.5 knot (kn). Mach numbers express speed relative to the speed of sound, used in aviation and aerospace.

This conversion is commonly needed for driving and speed limit compliance, running and fitness tracking, aviation and flight planning. Knots are the standard speed unit in maritime and aviation worldwide.

To put mach in perspective: a commercial jet (about Mach 0.85). In knot, common references include a cruise ship (about 20 kn).

Did you know?

Mach numbers are named after Austrian physicist Ernst Mach. The exact speed of Mach 1 varies with temperature and altitude.

Real-world examples
Mach (M)
  • a commercial jet (about Mach 0.85)
  • the speed of sound (Mach 1)
  • a bullet from a rifle (about Mach 2.5)
Knot (kn)
  • a cruise ship (about 20 kn)
  • a sailboat in good wind (about 6–8 kn)
  • a Category 1 hurricane (64–82 kn)
Did you know?

The term 'knot' originated from counting knots on a rope trailing behind a ship over a fixed time period.

Common uses for speed conversion
