A 100-watt device running for 10 hours uses 1,000 watt-hours, or 1 kWh.</p> <h2 id="the-formula">The formula</h2> <p>Use this:</p> <p><code>watts x hours = watt-hours</code></p> <p>Then divide by 1,000:</p> <p><code>watt-hours / 1,000 = kWh</code></p> <p>A 60-watt router and network setup running for 24 hours uses 1,440 Wh, or 1.44 kWh. A 1,500-watt appliance running for 20 minutes uses about 0.5 kWh. Short high-power loads and long low-power loads both matter.</p>
