Note that because right ascension is measured in time units, before performing calculations you need to multiply by 15 degrees/hr. The unit was formerly an SI supplementary unit , but this category was abolished in 1995 and the radian is now considered an SI derived unit. Arc Length – The distance from the tip of the electrode or wire to the work piece. If the central angle has $\alpha$ degrees; than the length of the arc is $\alpha$ times greater than the arc that matches the $ 1^{\circ}$ angle: $$ l (\alpha) = \frac{r\pi\alpha}{180^{\circ}}. Arc length is the distance between two points along a section of a curve. ” Sweep Angle, denoted by “SW.
