Kilowatt-Hour Formula
Cost = (Watts / 1000) * Daily Hours * Unit Rate * Days
Watts divided by 1000 derives Kilowatts. Multiply by hours used, electricity base cost (€/kWh) and duration.
Example
- A 2000W electric heater running 4 hours daily under a €0.30/kWh rate costs €2.40 daily.
⚠ Note
- Devices like fridges and air conditioners cycle on/off; they rarely draw maximum power continuously.
