WebDec 17, 2024 · Calculate power rating in kilovolts-amperes, or "KVA," when you know voltage and current rating. Use the formula: P (KVA) = VA/1000 where P (KVA) is power in KVA, V is voltage and A is current in amperes. For example, if V is 120 volts and A is 10 amperes, P (KVA) = VA/1000 = (120) (10)/1000 = 1.2 KVA. WebTo calculate the kVA rating of a machine from the amperage rating, just enter the value of current in amperes, voltage in volts, select power supply system ( single phase or three phase) and hit the “Calculate” button to the get the result of apparent power in kVA, VA, mVA and MVA.
