Watts represent the rate of energy consumption, showing how much power an appliance draws per second. Kilowatt‑hours (kWh) measure the total energy used over time and are the unit used on electric bills. To determine how much energy a device consumes, convert its power rating from watts to kilowatt‑hours.
If you have a 60‑W light bulb, it draws 60 W every hour of operation.
Divide the wattage by 1 000. 60 W ÷ 1 000 = 0.06 kW.
Multiply the kilowatt value by the number of hours the device runs. For a 60‑W bulb left on for 3 hours: 0.06 kW × 3 h = 0.18 kWh.
Understanding kWh consumption lets you estimate monthly costs, compare appliances, and identify opportunities to cut energy use.
Convert watts to kilowatt‑hours to gauge how much electricity you’re using and identify savings on your bill.
