1. What is BTU to kW Conversion?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to kilowatts (kW), two common units of power measurement.

Purpose: It helps in comparing or converting between different power measurement systems, commonly needed in HVAC, engineering, and energy applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Q_{btu} \) — Power in British Thermal Units per hour (BTU/h)

Explanation: 1 kW is equivalent to 3412 BTU/h, so we divide the BTU/h value by 3412 to get the equivalent in kW.

3. Importance of Power Unit Conversion

Details: Accurate conversion between units is essential for equipment specification, energy calculations, and system design in international projects where different measurement systems are used.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The result will show the equivalent power in kilowatts with high precision.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor between BTU/h and kW, based on the international definition of these units.

Q2: When would I need this conversion?
A: Common applications include comparing air conditioner capacities (often rated in BTU) with electrical systems (often rated in kW).

Q3: Is this conversion exact or approximate?
A: The conversion factor 3412 is exact, though practical applications may involve rounding.

Q4: Can I convert kW back to BTU?
A: Yes, multiply kW by 3412 to get BTU/h. We may add a reverse calculator in future updates.

Q5: How precise should I be with these conversions?
A: For most engineering purposes, 4-6 decimal places are sufficient, though our calculator shows full precision.
