1. What is kW to BTU/h 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 power ratings between different measurement systems, commonly used in heating and cooling systems.

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, based on the International Table BTU definition.

3. Importance of Power Unit Conversion

Details: Converting between kW and BTU/h is essential when working with equipment that uses different measurement systems, ensuring proper sizing and compatibility.

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 as the conversion factor?
A: This is the exact conversion factor based on the International Table BTU definition where 1 kW = 3412.142 BTU/h.

Q2: Is this conversion exact?
A: Yes, this is an exact conversion based on standardized definitions, not an approximation.

Q3: When would I need this conversion?
A: Commonly used when comparing heating/cooling systems, where some manufacturers use kW and others use BTU/h ratings.

Q4: Does this work for both heating and cooling?
A: Yes, the conversion applies equally to both heating and cooling power measurements.

Q5: How precise is this conversion?
A: The conversion is mathematically precise, though equipment ratings may have their own tolerances.
