1. What is kW to BTU Conversion?

Definition: This calculator converts power measurements from kilowatts (kW) to British Thermal Units per hour (BTU/h).

Purpose: It helps in comparing and converting between different power measurement systems used in heating, cooling, and electrical applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{btu} \) — Power in BTU per hour
• \( P_{kW} \) — Power in kilowatts

Explanation: 1 kW is equivalent to 3412 BTU/h, as 1 BTU/h equals approximately 0.000293071 kW.

3. Importance of Power Unit Conversion

Details: Converting between kW and BTU/h is essential when working with equipment specifications that use different measurement systems, particularly in HVAC and energy applications.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts (kW) and the calculator will automatically compute the equivalent BTU/h value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This comes from the definition of BTU and kW - 1 kW equals 3412.142 BTU/h based on the International Steam Table BTU definition.

Q2: Is this conversion exact?
A: The conversion is based on standard definitions, though slight variations exist between different BTU definitions (IT, thermochemical, etc.).

Q3: When would I need this conversion?
A: Common uses include sizing HVAC equipment, comparing heating system capacities, and converting electrical power to thermal output.

Q4: Can I convert BTU/h back to kW?
A: Yes, divide BTU/h by 3412 to get kW (or use our BTU to kW calculator).

Q5: Does this account for efficiency factors?
A: No, this is a direct unit conversion. For actual system performance, you would need to consider efficiency separately.
