Formula & Calculation Steps:
Watts = (kWh × 1000) / Hours
Converting kWh to Watts
By converting total energy (kWh) used over a known period into watts (W), you can find the average power rating of an appliance. This is highly useful for determining the baseline wattage for solar or inverter sizing.
$$ P_{(W)} = \frac{1000 \times E_{(kWh)}}{t_{(hr)}} $$
Power in Watts is 1000 times Energy in kWh divided by Time in hours.
