The calculator integrates a speed unit converter, it allows to make online easily and quickly
des **conversions in kilometers per hour (km/h), meters per second (m/s), miles per hour (mph), feet per second (fps), knots (kn)**.

The calculator offers the possibility to **convert speed**
to the main units in one operation : kilometers per hour (km/h), meters per second (m/s), miles per hour (mph), feet per second (fps), knots (kn).

Thus, it is possible to use the **speed converter** to obtain the conversion of 130 expressed in any speed,
en km/h, m/s, mph, fps, kn,
just type :
convert_speed(`130`) which will return 130 and all the possible conversions in the calculation details.

To perform the calculations, the calculator uses the main relationships that exist between the different speed units which have been obtained from the following equations.

- 1 miles = 1609.344 m
- 1 noeud = 1.852 km/h
- 1 fps = 0.3048 m/s

convert_speed(v) v, is a real number that represents the speed to convert.
