1. What is a BTU to kW Calculator for UK?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to kilowatts (kW) specifically for UK applications.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Q_{btu} \) — Heat transfer rate in British Thermal Units per hour (BTU/h)
• 3412 — Conversion factor (BTU/h per kW)

Explanation: 1 kW is equivalent to 3412 BTU/h, so dividing BTU/h by this factor gives the equivalent power in kW.

3. Importance of BTU to kW Conversion

Details: Accurate conversion is essential for equipment specification, energy calculations, and compliance with UK standards.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Is this different for US calculations?
A: No, the conversion factor is the same, but UK applications often use different standards for equipment ratings.

Q3: When would I need this conversion?
A: Common when working with HVAC systems, boilers, or comparing equipment specifications that use different units.

Q4: How precise is this conversion?
A: Very precise for most engineering purposes, using the standard International Table BTU definition.

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