How to Convert Feet per Second to Mach

Converting feet per second (ft/s) to Mach is a common conversion in aerodynamics and fluid dynamics. Mach number is the ratio of the speed of an object to the speed of sound in the surrounding medium.

Formula

Mach = Feet per Second ÷ 1125.33

or

mach = ft/s ÷ 1125.33

Step-by-step process

  1. Take the measurement in feet per second
  2. Divide that number by 1125.33 (the speed of sound in dry air at 20°C)
  3. The result is the equivalent Mach number

Examples

  • 1125.33 ft/s = 1 Mach
  • 2250.66 ft/s = 2 Mach
  • 562.665 ft/s = 0.5 Mach

When to Convert Feet per Second to Mach

This conversion is useful in aviation, aerospace engineering, and fluid dynamics, particularly when dealing with high-speed phenomena and supersonic flight.

Frequently Asked Questions

What is Foot per Second (ft/s)?

Foot per second (ft/s) is a unit of speed and velocity in the imperial and US customary systems, representing the distance in feet traveled per second.

What is Mach?

Mach is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Mach 1 is the speed of sound.
