kW to BTU Conversion Formula:
From: | To: |
Definition: This calculator converts power in kilowatts (kW) to heat output in British Thermal Units per hour (BTU/h).
Purpose: It helps in comparing electrical power to heating capacity, commonly used for HVAC systems and heaters.
The calculator uses the formula:
Where:
Explanation: 1 kW of electrical power is equivalent to 3412 BTU/h of heat output.
Details: This conversion is essential for sizing heating systems, comparing different energy sources, and understanding equipment specifications.
Tips: Simply enter the power in kilowatts (must be > 0) and the calculator will show the equivalent BTU/h output.
Q1: Why is the conversion factor 3412?
A: This comes from the definition of BTU and kW - 1 kW equals 3412.142 BTU/h exactly.
Q2: Can I use this for cooling systems?
A: Yes, the same conversion applies for cooling capacity in BTU/h.
Q3: Is this conversion exact?
A: Yes, it's a direct mathematical conversion, not an approximation.
Q4: What's a typical kW to BTU conversion for air conditioners?
A: A 1.5 kW AC unit would produce about 5,118 BTU/h of cooling (1.5 × 3412).
Q5: How does this relate to SEER ratings?
A: SEER ratings compare BTU/h of cooling to watts of electrical input over a season.
