Volt-Ampere (VA) to Horsepower (mechanical) Converter
Power · unit-converter
Convert Volt-Ampere (VA) to Horsepower (mechanical) with a fixed input and output unit, step-by-step formula line, and reference tables. Linear units use SI watt definitions; mechanical hp uses 550 ft·lbf/s; BTU/h uses the IT BTU; dBm/dBW are logarithmic relative to 1 mW and 1 W. The full Power Converter also includes PS/CV, TR, kVA/MVA, and ft·lb/s.

About Volt-Ampere (VA)
Volt-amperes describe apparent power in AC circuits. At unity power factor, VA matches real power in watts; this tool uses that 1:1 mapping for conversion.
About Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
How to convert volt-amperes (va, unity pf) to horsepower (mechanical, 550 ft·lb/s)
1 volt-ampere (va) is equal to 0.0013410220896 horsepower (mechanical) when both are expressed in watt-equivalents:
1 va = (1 W ÷ 745.6998715822702 W) hp = 0.0013410220896 hp
Each volt-ampere (va) is defined as 1 W and each horsepower (mechanical) as 745.6998715822702 W in this tool, so one va equals 1 ÷ 745.6998715822702 hp = 0.0013410220896 hp.
Let d(va) be the numeric value in Volt-Ampere (VA) (va), and d(hp) the value in Horsepower (mechanical) (hp). Then:
d(hp) = d(va) × (1 / 745.6998715822702)
Equivalently, divide by how many va fit into one hp (watts per hp divided by watts per va):
d(hp) = d(va) ÷ 745.69987158227025
Or: horsepower (mechanical) = volt-ampere (va) ÷ 745.69987158227025
Examples
Example #1: Convert 1 va to horsepower (mechanical)
1 va = 1 va × (1/745.6998715822702) hp = 0.0013410221 hp
1 va = 1 va ÷ 745.69987158227025 = 0.0013410221 hp
Intermediate watts: 1 W
Example #2: Convert 10 va to horsepower (mechanical)
10 va = 10 va × (1/745.6998715822702) hp = 0.0134102209 hp
10 va = 10 va ÷ 745.69987158227025 = 0.0134102209 hp
Intermediate watts: 10 W
Summary
To convert Volt-Ampere (VA) to Horsepower (mechanical), multiply the value in va by the ratio of watts per va divided by watts per hp. Equivalently: value_hp = value_va × (1 / 745.6998715822702). Numerically, 1 va equals 0.0013410220895950279 hp.
Relationship context
You are converting between apparent power at unity PF (VA) (Volt-Amperes (VA, unity PF)) and mechanical power (horsepower, ft·lb/s) (Horsepower (mechanical, 550 ft·lb/s)). All linear values are mapped through watts first. The numeric factor is 1.341022e-3.
