Speed Converter – Convert Between Units of Speed

Use this online speed converter tool to convert between units for measuring speed (magnitude of velocity).

How To Convert Units of Measurement?

Step 1: Identify the starting unit

The first step is to identify the base unit of measure. This is the unit from which you need to convert to another unit.

For example, if you need to convert from knots to meters per second, then knots should be your base unit.

Step 2: Identify the resulting unit

The next step is to identify the converting unit. It is the unit you want to convert your measurement to.

Step 3: Find the conversion factor

This step is to find the conversion factor from the base unit to the resulting unit.

Say, if you need to convert from miles per hour to the speed of sound, then your conversion factor will be 0.001303 which means 1 miles per hour = 0.001303 speed of sound.

Please check the table of 'Conversion Factors' below:

Step 4: Perform Math

Once you have the based unit, the resulting unit, and the conversion factor, the last step is to perform the basic math.

Here is the calculation to convert from 25 miles per hour to the speed of sound:

25 miles per hour= 25 * 0.001303 speed of sound= 0.032583 speed of sound

Length Conversion Examples

Knots to Miles Per Hour conversion example

Task: Convert 75 knots to miles per hour

Formula: 75 knots is equal to approximately 1.150779 miles per hour

Calculation: 75 * 1.150779 = 86.308459 miles per hour

Kilometers Per Second to Kilometers Per Hour conversion example

Task: Convert 500 cubic feet to cubic yard

Formula: 1 kilometer per second is equal to approximately 3600 kilometers per hour

Calculation: 500 * 3600= 1,800,000 kilometers per hour

Meters Per Second to Kilometers Per Second conversion example

Task: Convert 1000 meters per second to kilometers per second

Formula: 1 meter second is equal to approximately 0.001 kilometers per second

Calculation: 1000 * 0.001 = 1 kilometer
