1. What is a kW to BTU Calculator?

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

Purpose: It helps HVAC professionals, engineers, and energy analysts convert between these common power units.

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 equals 3412 BTU/h by definition. This conversion factor comes from the relationship between the two units.

3. Importance of Power Unit Conversion

Details: Many heating and cooling systems use BTU ratings while electrical systems use kW, making conversions essential for system design and comparison.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts (must be > 0) and the calculator will provide the equivalent in BTU/h.

5. Frequently Asked Questions (FAQ)

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

Q2: When would I need this conversion?
A: Common when comparing electric heaters (kW) to gas heaters (BTU) or sizing HVAC equipment.

Q3: Is this for BTU/h or just BTU?
A: The result is in BTU per hour (BTU/h), which is a power unit comparable to kW.

Q4: How precise is this conversion?
A: The conversion is mathematically exact, though real-world measurements may have precision limitations.

Q5: Can I convert BTU back to kW?
A: Yes, simply divide BTU/h by 3412 to get kW.
