The **Impulse Speed** calculator translates Impulse Speed into common velocity units such as miles per hour. This calculation is based on the fictional series Star Trek. However, it is a useful (exponential) scale for measuring speed in relationship to astronomical distances.

**INSTRUCTIONS:** Enter the following:

- (
**t**) Time travelling at Impulse Speed - (
**i**) Impulse Factor

The calculator returns the distance travelled.

Impluse Speed is a multiple of a fixed sub-light speed (¼ C). The formula for velocity using impulse speed is as follows:

Distance = i • 0.25 • C • t

where C is the speed of light: 186,000 miles per second.
