1. What is BTU to kWh Conversion?

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

Purpose: It helps in comparing energy usage between systems that use different measurement units, particularly in heating and cooling applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy in kilowatt-hours (kWh)
• \( Q \) — Energy in British Thermal Units (BTU)
• 3412 — Conversion factor (BTU per kWh)

Explanation: 1 kWh is equivalent to 3412 BTU, so we divide the BTU value by 3412 to get the equivalent kWh.

3. Importance of BTU to kWh Conversion

Details: This conversion is essential for energy efficiency comparisons, utility bill calculations, and when working with equipment that uses different energy measurement standards.

4. Using the Calculator

Tips: Simply enter the energy value in BTU and the calculator will automatically compute the equivalent in kWh.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor where 1 kWh = 3412.141633 BTU, based on the International Steam Table BTU definition.

Q2: When would I need this conversion?
A: Common uses include comparing air conditioner efficiency (often rated in BTU) with electricity usage (measured in kWh).

Q3: Is this conversion exact?
A: Yes, the 3412 factor is an exact conversion, though different BTU definitions exist (e.g., thermochemical BTU = 3414).

Q4: How many BTU are in 1 kWh?
A: Exactly 3412 BTU per kWh (using the International Steam Table BTU definition).

Q5: Can I convert kWh back to BTU?
A: Yes, simply multiply kWh by 3412 to get BTU.
