1. What is an Electric BTU per kWh Calculator?

Definition: This calculator converts electrical energy in kilowatt-hours (kWh) to British Thermal Units (BTU).

Purpose: It helps compare electrical energy with thermal energy units, useful for HVAC systems and energy efficiency calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Thermal energy (BTU)
• \( E \) — Electrical energy (kWh)
• 3412 — Conversion factor (BTU per kWh)

Explanation: Each kilowatt-hour of electricity is equivalent to 3,412 BTU of thermal energy.

3. Importance of BTU Calculation

Details: Understanding this conversion helps in sizing heating/cooling systems and comparing energy costs between different fuel types.

4. Using the Calculator

Tips: Simply enter the electrical energy consumption in kWh. The result shows the equivalent thermal energy in BTU.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the standard conversion based on the definition of BTU and kWh (1 kWh = 3,412 BTU).

Q2: Does this account for system efficiency?
A: No, this is a direct conversion. For actual system output, multiply by the system's efficiency factor.

Q3: Can I use this for heat pumps?
A: Yes, but remember heat pumps typically deliver more BTU than the electrical input due to their COP.

Q4: How accurate is this conversion?
A: It's theoretically exact for perfect conversion, but real-world systems have efficiency losses.

Q5: What's a typical kWh to BTU conversion for appliances?
A: Most electric heaters produce exactly 3,412 BTU per kWh, while other devices may vary.
