P(W) = 1000 x E(kWh) / t(h) The power P in watts (W) is equal to 1000, multiplied by the energy E in kilowatt-hours (kWh), divided by the consumption time period t in hours (h). Understand the relationship between energy and power in electrical systems. For example, if a device consumes 2 kWh of energy over 4 hours, the average power is (2 × 1000) / 4 = 500 watts. Here's the formula for that: watt-hour = kilowatt-hours x 1000 (1) Then to finally convert watt-hour to watts, we'll divide watt-hours by hours: watts = watt-hour ÷ hours (2) We can compress the two formulas. .
