How to calculate power in kW?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
To calculate power in kilowatts, first calculate watts using the standard formulas, then divide by 1,000: kW = Watts ÷ 1,000
For example, if a device uses 3,500 watts, that's 3,500 ÷ 1,000 = 3.5 kW. Alternatively, you can use the formula directly: kW = (V × I) ÷ 1,000.
