One kilowatt hour equals exactly 1,000 watt hours. The prefix "kilo" means 1,000.
Multiply the kWh value by 1,000. For example, 3.5 kWh × 1,000 = 3,500 Wh.
A 60 W light bulb uses 60 Wh per hour. A 1,500 W space heater uses 1,500 Wh (1.5 kWh) per hour. A refrigerator uses roughly 100-200 Wh per hour.
Watts measure power (rate of energy use). Watt hours measure energy (total consumption). A 100 W device running for 5 hours uses 500 Wh.
