1. What is BTU to kW Conversion?

The BTU (British Thermal Unit) to kW (kilowatt) conversion is used to convert heating and cooling capacity measurements between imperial and metric systems. This is particularly important for radiator sizing and HVAC system specifications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( BTU \) — British Thermal Units per hour
• \( kW \) — Kilowatts
• \( 3412 \) — Conversion factor (BTU to kW)

Explanation: One kilowatt is equivalent to 3412 BTU per hour, making this conversion essential for international standards and equipment compatibility.

3. Importance of Radiator Output Calculation

Details: Accurate radiator output calculation is crucial for proper heating system design, energy efficiency, room comfort, and avoiding under or over-sized heating systems.

4. Using the Calculator

Tips: Enter BTU value in BTU per hour. The calculator will automatically convert to kilowatts. Ensure the BTU value is positive and represents the radiator's hourly output.

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU to kW?
A: kW is the standard metric unit for power, while BTU is commonly used in imperial systems. Conversion ensures compatibility with international equipment and standards.

Q2: What is the conversion factor 3412?
A: 3412 BTU/h equals 1 kW, as 1 watt = 3.412 BTU/h, therefore 1000 watts (1 kW) = 3412 BTU/h.

Q3: How do I find my radiator's BTU rating?
A: Check manufacturer specifications, product labels, or technical datasheets. Most modern radiators display both BTU and kW ratings.

Q4: What is typical radiator output range?
A: Residential radiators typically range from 2,000-15,000 BTU/h (0.6-4.4 kW), depending on size and type.

Q5: Can I use this for air conditioning units?
A: Yes, this conversion works for any heating or cooling equipment rated in BTU/h, including air conditioners and heat pumps.
