Energy Consumption Formula:
From: | To: |
The kW to kWh conversion calculates energy consumption by multiplying power (in kilowatts) by time (in hours). This is essential for understanding electricity usage and costs in the UK energy market.
The calculator uses the simple energy formula:
Where:
Explanation: This formula calculates the total energy consumed by an electrical device or system over a specific period of time.
Details: Accurate energy calculation is crucial for electricity billing, energy efficiency planning, carbon footprint assessment, and understanding appliance running costs in UK households and businesses.
Tips: Enter the power rating in kilowatts (kW) and the operating time in hours. Both values must be positive numbers. For appliances rated in watts, divide by 1000 to convert to kilowatts.
Q1: What's the difference between kW and kWh?
A: kW (kilowatt) measures power (rate of energy use), while kWh (kilowatt-hour) measures energy (total consumption over time).
Q2: How do I convert watts to kilowatts?
A: Divide the watt value by 1000. For example, 1500 watts = 1.5 kW.
Q3: What is the average UK electricity cost per kWh?
A: As of 2024, the average UK electricity price is around 28-34 pence per kWh, but this varies by supplier and tariff.
Q4: How accurate is this calculation for real-world usage?
A: This provides a theoretical maximum. Actual consumption may vary based on appliance efficiency, load variations, and other factors.
Q5: Can I use this for solar panel calculations?
A: Yes, this formula works for both energy consumption and energy production calculations for solar panels and other generation systems.
