A unit of space craft speed measurement used by the Arshans.
This article is a work in progress and may be incomplete or subject to change.
In Arshan culture, an 'impulse' is a unit of speed measurement commonly used for space craft. One impulse is the equivalent of the cruising speed attained by the first space-faring Arshan space craft - A vessel named the 'Impulse'. Measurements in this unit are generally written as 'N impulse', where the portrayed speed is N times the speed of the original Impulse.
One impulse is the equivalent of 1/5 Solus Star-Miles/Hour. Impulse can be converted to star-miles/hour with this equation:
S = I * 4.91
