To convert knots to mach, multiply the value by the conversion factor:

1 kn = 0.00149984 Ma

For example: 10 kn = 0.0149984 Ma

The Conversion Formula

To convert knots to mach, multiply the value by the conversion factor: 1 kn = 0.00149984 Ma. For a worked example, suppose you need to convert 25 kn to mach: 25 × 0.00149984 = 0.0374959 Ma. To convert in the opposite direction, divide by 0.00149984, or equivalently multiply by 666.74.

About knots

The knot is a unit with a literal history: sailors used to measure speed by throwing a log overboard attached to a rope with knots tied at specific intervals. They counted the knots that slipped through their hands in a set time. One knot equals one nautical mile per hour. It remains the global standard for maritime and aviation operations. knots are commonly used in Ship speed, Aircraft airspeed, Cruise missile velocity, and Wind speed (Marine), Naval operations.

A large cruise ship travels at about 20-25 knots.

About mach

Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Named after Ernst Mach, 'Mach 1' is the speed of sound. It varies with temperature and altitude. It is the language of supersonic flight and high-speed aerodynamics. mach are commonly used in Fighter jets, Rockets and missiles, Supersonic transport, and Space shuttle re-entry, Aerodynamic testing.

A commercial airliner cruises around Mach 0.8.

When Would You Convert knots to mach?

Converting between knots and mach is one of the most common speed conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 kn = 0.00149984 Ma) memorized or bookmarked can save time in professional and everyday contexts alike.
