kva to kw converter
The tool opens in Apparent (VA) mode with the rating already entered. Change the power factor to the one on your unit and read the real power in W and the current at your voltage.

1,000 × 0.6.
1,500 ÷ 127.
3,000 ÷ 120.
10 ÷ 0.8.
At 220 V, 25 A (5,500 ÷ 220). At 127 V, 43.3 A (5,500 ÷ 127). A heater element is a pure resistance, so the power factor is 1. That figure is the appliance current: it does not say which breaker or wire to use, which is a job for a licensed electrician.
It depends on the power factor: 900 W at 0.9, 800 W at 0.8, 600 W at 0.6. The factor is in the equipment manual.
Only when the power factor is 1. In general kW = kVA × cosφ, so kW is less than or equal to kVA.
Look on the label or datasheet under output power factor. Modern units often list W and VA side by side, and their ratio is the factor.
Use the voltage that reaches the appliance: line-to-neutral (120 V) or across two lines (240 V). Line-to-line in a three-phase system, 120 V line-to-neutral becomes about 381.1 V.
Typical nameplate powers, only as a starting point. Every model differs: the label on your appliance rules. Edit the value freely.
I = 5,500 ÷ (220 × 1) = 25 A
Running for 1 hour it uses 5.5 kWh.

Current of each appliance at 120 V and 240 V with cosφ 1 (the field above). Motors and compressors often have cosφ below 1: change the field to see the effect.
Limit of this tool. It shows the current and powers implied by the load you enter. It does not size a breaker or a cable: that depends on installation method, length, circuit grouping and temperature, and belongs to a licensed electrician or engineer following your local code.
