"1 unit" of electricity typically refers to **1 kilowatt-hour (kWh)** — this is a measure of **energy**, not power.
### Here's how it breaks down:
- **1 unit = 1 kilowatt-hour (kWh)**
- **1 kilowatt-hour = 1,000 watts used for 1 hour**
So, **1 unit = 1,000 watts × 1 hour**
To summarize:
- If you use a **1,000-watt (1 kW)** appliance for **1 hour**, you consume **1 unit (1 kWh)** of electricity.
- If you use a **100-watt bulb** for **10 hours**, that also consumes **1 unit**.
