1. What is kWh to BTU per Hour Conversion?

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

Purpose: It helps in comparing energy usage between electrical systems (measured in kWh) and thermal systems (measured in BTU/h).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Power (BTU per hour)
• \( E \) — Energy (kilowatt-hours)

Explanation: 1 kWh is equal to 3412 BTU, so multiplying kWh by 3412 converts energy to BTU per hour when considering a 1-hour time period.

3. Importance of Energy Conversion

Details: This conversion is essential for HVAC system sizing, energy efficiency comparisons, and understanding equipment specifications that use different units.

4. Using the Calculator

Tips: Simply enter the energy value in kilowatt-hours (kWh). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 as the conversion factor?
A: 1 kWh equals exactly 3412.142 BTU according to the International Steam Table calorie definition.

Q2: Is this conversion time-dependent?
A: Yes, this specifically converts kWh (energy) to BTU/h (power), assuming the energy was used over one hour.

Q3: Can I convert BTU/h back to kWh?
A: Yes, divide BTU/h by 3412 to get kWh (for one hour of operation).

Q4: How accurate is this conversion?
A: It's precise for most practical applications, though slight variations exist in different measurement standards.

Q5: When would I need this conversion?
A: Common uses include comparing electric heaters to gas heaters, or when working with hybrid energy systems.
