Energy Consumption Formula:
| From: | To: |
Energy consumption calculation helps determine the amount of electrical energy used by appliances and devices. It's essential for understanding electricity costs and managing energy usage effectively, particularly in Malaysia where electricity tariffs apply.
The calculator uses the energy consumption formula:
Where:
Explanation: This formula converts power consumption from watts to kilowatts (by dividing by 1000) and multiplies by the number of hours to get total energy consumption in kilowatt-hours.
Details: Calculating energy consumption helps in budgeting electricity costs, identifying energy-efficient appliances, and reducing carbon footprint. In Malaysia, this is particularly important due to tiered electricity pricing.
Tips: Enter power consumption in watts and hours of usage. Both values must be positive numbers. The result shows energy consumption in kilowatt-hours (kWh).
Q1: Why convert watts to kilowatts?
A: Electricity is billed in kilowatt-hours, so converting to kilowatts provides the standard unit for energy consumption measurement.
Q2: How accurate is this calculation?
A: The calculation provides a theoretical estimate. Actual consumption may vary based on appliance efficiency, voltage fluctuations, and usage patterns.
Q3: Can I use this for multiple appliances?
A: Yes, calculate each appliance separately and sum the results to get total energy consumption.
Q4: How does this relate to Malaysian electricity bills?
A: Malaysian electricity tariffs are charged per kWh, so this calculation helps estimate your electricity costs.
Q5: What's the typical power consumption of household appliances?
A: Power consumption varies: LED bulb (5-15W), refrigerator (100-400W), air conditioner (900-5000W). Check appliance labels for specific wattage.
