All Power Conversion Calculators

Every converter on kVA to kW: 29 calculators covering apparent power, current, energy, mechanical power and thermal loads.

Power & apparent power

Move between kW, kVA, VA, MW, MVA, GW and watts at any power factor.

kW to kVAkVA = kW ÷ PFkVA to MWMW = kVA × PF ÷ 1,000kVA to MVAMVA = kVA ÷ 1,000VA to kVAkVA = VA ÷ 1,000VA to kWkW = VA × PF ÷ 1,000kVA to WattsW = kVA × 1,000 × PFkW to WattsW = kW × 1,000kW to GWGW = kW ÷ 1,000,000kVA to kW (Single Phase)kW = kVA × PF

Current & voltage

Full-load current, voltage and power for single-phase and three-phase supplies.

kVA to AmpsA = kVA × 1,000 ÷ (V × √3 for 3-phase)kVA to Amps (Three Phase)A = kVA × 1,000 ÷ (√3 × V)Amps to kWkW = √3 × V × A × PF ÷ 1,000kW to VoltsV = kW × 1,000 ÷ (√3 × A × PF)

Energy over time

Turn a power rating into kWh, MWh, GJ, kJ or joules — and what it costs.

kW to kWhkWh = kW × hourskW to MWhMWh = kW × hours ÷ 1,000kW to GJGJ = kW × hours × 0.0036kW to kJkJ = kW × secondskW to JoulesJ = kW × 1,000 × seconds

Mechanical power

Horsepower, brake horsepower, torque, shaft speed and engine displacement.

kW to HPhp = kW × 1.34102kW to BHPbhp = kW × 1.34102kW to NmN·m = 9549.3 × kW ÷ rpmkW to TorqueT = 9549.3 × kW ÷ rpmkW to RPMrpm = 9549.3 × kW ÷ N·mkW to CCcc = (kW ÷ kW per litre) × 1,000

Thermal & fluid

HVAC and hydraulic conversions: BTU/hr, tons, water flow, airflow and pressure.

kW to BTU/hrBTU/hr = kW × 3,412.142kW to TonTR = kW ÷ 3.51685kW to GPMGPM = BTU/hr ÷ (500 × ΔT)kW to CFMCFM = BTU/hr ÷ (1.08 × ΔT)kW to PSIbar = kW × η × 600 ÷ L/min
