Speed Of Sound Calculator

How do you Calculate the Speed of Sound?

The speed of sound can be calculated with the following formula, if the sound waves are traveling through normal air and not underwater or elsewhere:

• T = Temperature

Understanding Your Results

The result from this tool is the speed of sound in dry conditions with relatively fine humidity and above water. This tool will not be able to calculate the speed of sound in unique situations with other factors impacting it so keep that in mind!

When you get your answer it will be displayed by default in feet per second but it can be easily converted into other units of speed measurement with the click of a button.

How to Use the Speed of Sound Tool

Calculating the speed of sound has never been easier. With our free-to-use tool it takes a few steps to get the speed of sound. The steps required include:

1. Enter the air temperature. Select the correct temperature unit if Fahrenheit is not it.


2. Hit calculate and get the speed of sound in under a second!

Example Calculation

Let's say you want to identify the speed of sound when it is 40 degrees Fahrenheit outside. To do so all you need to do is enter 40 into the single field of this tool, then hit calculate. You would get an answer of 1,095.78 feet per second, but we can easily convert this to miles per hour by selecting it from the dropdown selector to get an answer of 747.12 miles per hour.
