Cable Length

Estimates the cable length using the parabolic approximation formula: L = S + (8d²) / (3S), where S is the cable span and d is the midpoint sag. Supports unit conversion via multipliers.

Inputs

Cable Span

Horizontal distance between the two cable supports

Cable Span Unit Multiplier

Unit multiplier for span — mm: 10, cm: 1, dm: 0.1, m: 0.01, km: 0.00001, in: 0.3937007874016, ft: 0.03280839895013, yd: 0.01093613298338

Cable Sag

Maximum sag at the midpoint of the cable

Result Unit Multiplier

Unit multiplier for output — mm: 10, cm: 1, dm: 0.1, m: 0.01, km: 0.00001, in: 0.3937007874016, ft: 0.03280839895013, yd: 0.01093613298338
