1. What is kWh to BTU/hr Conversion?

Definition: This calculator converts energy in kilowatt-hours (kWh) to power in British Thermal Units per hour (BTU/hr).

Purpose: It helps in comparing or converting between electrical energy and thermal power units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Power in BTU/hr
• \( E \) — Energy in kWh

Explanation: 1 kWh is equivalent to 3412 BTU/hr, as 1 kWh = 3412.142 BTU.

3. Importance of This Conversion

Details: This conversion is essential for HVAC system design, energy efficiency calculations, and comparing electrical and thermal systems.

4. Using the Calculator

Tips: Simply enter the energy value in kWh. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This comes from the definition of kWh and BTU - 1 kWh equals exactly 3412.142 BTU.

Q2: Is this conversion exact?
A: Yes, the conversion factor is mathematically exact, not an approximation.

Q3: Can I convert BTU/hr back to kWh?
A: Yes, by dividing BTU/hr by 3412 instead of multiplying.

Q4: When would I need this conversion?
A: Common in HVAC work, when comparing electric heaters to gas systems, or calculating cooling loads.

Q5: Does this account for efficiency losses?
A: No, this is a direct unit conversion. Efficiency factors would need to be applied separately.
