Results in Speed Of Sound: 1 mph = 0.001303 sound

## How to Convert Miles Per Hour to Speed Of Sound

To convert a mile per hour measurement to a speed of sound measurement, multiply the speed by the conversion ratio.

Since one mile per hour is equal to 0.001303 speed of sound, you can use this simple formula to convert:

speed of sound = miles per hour × 0.001303

The speed in speed of sound is equal to the miles per hour multiplied by 0.001303.

For example, here's how to convert 500 miles per hour to speed of sound using the formula above.
500 mph = (500 × 0.001303) = 0.651662 sound Miles per hour and speed of sound are both units used to measure speed. Keep reading to learn more about each unit of measure.

## Miles Per Hour

Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.

The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour can be expressed using the formula:
vmph = dmithr

The velocity in miles per hour is equal to the distance in miles divided by time in hours.

## Speed Of Sound

The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343 meters per second, or roughly 767 miles per hour.

Speed of sound can be abbreviated as sound; for example, 1 speed of sound can be written as 1 sound.
