Horsepower (mechanical) to Volt-Ampere (VA) Converter
Power · unit-converter
Convert Horsepower (mechanical) to Volt-Ampere (VA) 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 Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
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.
How to convert horsepower (mechanical, 550 ft·lb/s) to volt-amperes (va, unity pf)
1 horsepower (mechanical) is equal to 745.69987158227025 volt-ampere (va) when both are expressed in watt-equivalents:
1 hp = (745.6998715822702 W ÷ 1 W) va = 745.69987158227025 va
Each horsepower (mechanical) is defined as 745.6998715822702 W and each volt-ampere (va) as 1 W in this tool, so one hp equals 745.6998715822702 ÷ 1 va = 745.69987158227025 va.
Let d(hp) be the numeric value in Horsepower (mechanical) (hp), and d(va) the value in Volt-Ampere (VA) (va). Then:
d(va) = d(hp) × (745.6998715822702 / 1)
Equivalently, divide by how many hp fit into one va (watts per va divided by watts per hp):
d(va) = d(hp) ÷ 0.0013410220896
Or: volt-ampere (va) = horsepower (mechanical) ÷ 0.0013410220896
Examples
Example #1: Convert 1 hp to volt-ampere (va)
1 hp = 1 hp × (745.6998715822702/1) va = 745.699871582 va
1 hp = 1 hp ÷ 0.0013410220896 = 745.699871582 va
Intermediate watts: 745.699871582 W
Example #2: Convert 10 hp to volt-ampere (va)
10 hp = 10 hp × (745.6998715822702/1) va = 7456.99871582 va
10 hp = 10 hp ÷ 0.0013410220896 = 7456.99871582 va
Intermediate watts: 7,456.99871582 W
Summary
To convert Horsepower (mechanical) to Volt-Ampere (VA), multiply the value in hp by the ratio of watts per hp divided by watts per va. Equivalently: value_va = value_hp × (745.6998715822702 / 1). Numerically, 1 hp equals 745.6998715822702 va.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Horsepower (mechanical, 550 ft·lb/s)) and apparent power at unity PF (VA) (Volt-Amperes (VA, unity PF)). All linear values are mapped through watts first. The numeric factor is 7.456999e+2.
