Calculate Cable Length from Sag, Span

Cable or conductor length is a measure of one tenth of a nautical mile or approximately 100 fathoms. The original length of the cable is always shorter than the cable length in any transmission line between two points as there will be always certain sag involved. Cable usually lies in a parabolic shape as it is not a stiff object. Use this online calculator to calculate cable length from sag, span values of the cable. Cable length is a nautical unit.

Result :

You can use the formula mentioned above to find the cable length by computing the cable span and cable sag. Cable length can also be referred as the length of a cable or conductor.
