MPH to Mach Conversion: A Comprehensive Guide

Introduction

Miles per hour (mph) and Mach number are two different units of speed. Mach number is a dimensionless quantity that represents the ratio of the speed of an object to the speed of sound in the surrounding medium. It is often used to describe the speed of aircraft, missiles, and other high-speed objects.

Converting MPH to Mach

To convert mph to Mach, you need to know the speed of sound in the medium through which the object is traveling. The speed of sound in air at sea level is approximately 767 mph. To convert mph to Mach, you can use the following formula:

Mach number = Speed (mph) / Speed of sound (mph)

Example

If an aircraft is traveling at 1,200 mph at sea level, its Mach number is:

Mach number = 1,200 mph / 767 mph = 1.56

This means that the aircraft is traveling at 1.56 times the speed of sound.

Converting Mach to MPH

To convert Mach to mph, you need to know the speed of sound in the medium through which the object is traveling. The speed of sound in air at sea level is approximately 767 mph. To convert Mach to mph, you can use the following formula:

Speed (mph) = Mach number * Speed of sound (mph)

Example

If an aircraft is traveling at Mach 2 at sea level, its speed in mph is:

Speed (mph) = 2 * 767 mph = 1,534 mph

This means that the aircraft is traveling at 1,534 mph.
