1. What is a British Gas kWh Calculator?

Definition: This calculator estimates the energy consumption in kilowatt-hours (kWh) based on power in kilowatts (kW) and time in hours.

Purpose: It helps British Gas customers understand and calculate their electricity usage for better energy management and cost estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{kWh} = P_{kW} \times t \]

Where:

\( E_{kWh} \) — Energy consumption (kilowatt-hours)
\( P_{kW} \) — Power (kilowatts)
\( t \) — Time (hours)

Explanation: The power consumption is multiplied by the duration of use to determine total energy consumed.

3. Importance of kWh Calculation

Details: Understanding kWh consumption helps in budgeting electricity costs, comparing appliance efficiency, and reducing energy waste.

4. Using the Calculator

Tips: Enter the appliance power in kW and the duration of use in hours. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find an appliance's power rating?
A: Check the label or manual for wattage (W), then divide by 1000 to get kW (1 kW = 1000 W).

Q2: Can I use this for gas consumption?
A: No, this calculates electrical energy only. Gas is measured differently (in cubic meters or therms).

Q3: How accurate is this calculation?
A: It provides theoretical consumption. Actual usage may vary based on efficiency, power fluctuations, and usage patterns.

Q4: How does this relate to my British Gas bill?
A: British Gas bills show consumption in kWh. This calculator helps estimate usage before you receive your bill.

Q5: What's a typical kWh consumption for household appliances?
A: A 1kW device running for 1 hour uses 1 kWh. A 100W bulb uses 0.1 kWh per hour.
