1. What is kW to BTU/hr Conversion?

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

Purpose: It helps in comparing or converting between electrical power (kW) and thermal energy flow rate (BTU/hr).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{btu} \) — Thermal energy flow rate (BTU/hour)
• \( P_{kW} \) — Electrical power (kilowatts)

Explanation: 1 kW is equivalent to 3412 BTU/hr, as 1 BTU = 0.00029307107 kW.

3. Importance of kW to BTU/hr Conversion

Details: This conversion is essential when comparing electrical systems with heating/cooling systems that use BTU ratings.

4. Using the Calculator

Tips: Simply enter the power in kilowatts (kW) to get the equivalent BTU/hr value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This comes from the exact conversion where 1 kW = 3412.142 BTU/hr based on the International Table BTU definition.

Q2: When would I need this conversion?
A: Common when sizing HVAC equipment, comparing electric heaters to gas heaters, or working with mixed-unit specifications.

Q3: Is this conversion exact?
A: Yes, for International Table BTU. Other BTU definitions (like Thermochemical BTU) would use slightly different factors.

Q4: How do I convert BTU/hr back to kW?
A: Divide BTU/hr by 3412, or use our BTU/hr to kW calculator.

Q5: Does this account for efficiency or power factor?
A: No, this is a direct unit conversion. Actual system performance may vary based on efficiency and other factors.
