Fps to Mach Converter

How to convert feet per second to Mach

FormulaMa = ft/s × 0.0008957066032

Multiply the value in feet per second by 0.0008957066032. To go the other way, multiply by 1,116.437008 (or divide by 0.0008957066032).

A foot per second is smaller than a Mach: it takes 1,116.437008 feet per second to make one Mach.

About the units

Foot per second (ft/s)

Exactly 0.3048 m/s. Used for projectile and fluid velocities in US engineering.

Mach (Ma)

The speed of sound depends on air temperature. This converter uses the International Standard Atmosphere value at sea level, 15 °C: about 340.29 m/s (1,225 km/h, 761 mph). Mach depends on air temperature; this uses the ISA sea-level speed of sound, 340.29 m/s (15 °C).

Frequently asked questions

How many Mach are in one foot per second?

There are 0.0008957066032 Mach in one foot per second.

How do I convert feet per second to Mach?

Multiply the number of feet per second by 0.0008957066032. For example, 10 ft/s × 0.0008957066032 = 0.008957066032 Ma.

How many feet per second are in one Mach?

One Mach equals 1,116.437008 feet per second. That is the reverse factor, 1 ÷ 0.0008957066032.

What is 10 feet per second in Mach?

10 ft/s = 0.008957066032 Ma.

Is this ft/s to Ma converter accurate?

The conversion uses the accepted reference value (Mach depends on air temperature; this uses the ISA sea-level speed of sound, 340.29 m/s (15 °C).). Results are shown to 12 significant figures by default; adjust precision in the converter.
