kW · kVA · HP Converter

Type a value in any unit. The other four update live. Adjust voltage, power factor, and motor efficiency to model real-world conditions.

Real Power
kW · kilowatts
Apparent Power
kVA · kilovolt-amperes
Mechanical Power
HP · horsepower (motor output)
Current
A · amperes (line current)
Heat Equivalent
BTU/hr · British thermal units / hour
Reactive Power
kVAR · kilovolt-amperes reactive
Formulas applied — 3-phase, V = 480 V, PF = 0.9, η = 0.92
kVA = kW / PF · HP = kW · η / 0.746 · A = kW·1000 / (√3 · V · PF)
BTU/hr = kW · 3412 · kVAR = kVA · sin(arccos(PF))
