Introduction: The Kilowatt Calculator is a useful tool for estimating the cost of electricity usage. Whether you want to know how much it costs to run an appliance or an entire household, this calculator can provide you with an estimate.
Formula: To calculate the electricity cost, you can use the following formula:
- Electricity Cost = Power (in kilowatts) × Hours of Usage × Electricity Rate (per kWh)
How to Use:
- Enter the power consumption of your device or household in kilowatts (kW).
- Input the number of hours the device or household is in use.
- Specify the electricity rate, which is the cost per kilowatt-hour (kWh).
- Click the "Calculate" button.
- The calculator will display the estimated electricity cost.
Example: Let's say you have a 1.5 kW air conditioner running for 8 hours a day, and the electricity rate is $0.15 per kWh. The estimated electricity cost would be 1.5 kW × 8 hours × $0.15/kWh = $1.80.
FAQs:
