kW to BTU Converter: Convert Kilowatts to BTU
Convert kilowatts (kW) to British Thermal Units (BTU) for heating, cooling, and energy applications. This calculator helps you determine the equivalent energy in BTU based on power input in kilowatts.
Understanding kW to BTU Conversion
Converting kilowatts (kW) to British Thermal Units (BTU) is essential for understanding energy requirements in heating, cooling, and power systems. This conversion helps in comparing energy usage across different systems and units.
Key Factors in kW to BTU Conversion
The conversion from kW to BTU depends on the following:
| Factor | Description | Impact on Conversion |
|---|---|---|
| kW | Kilowatts, a measure of power | Higher kW values result in higher BTU values |
| Conversion Factor | 1 kW = 3412.142 BTU/h | Fixed factor for accurate conversion |
Formula for kW to BTU Conversion
The formula to convert kW to BTU is:
BTU = kW × 3412.142
Where:
- kW: Kilowatts
- BTU: British Thermal Units per hour (BTU/h)
Common Applications
| Application | Typical kW Range | Typical BTU Range |
|---|---|---|
| Portable Heaters | 1.5 - 2.9 kW | 5,000 - 10,000 BTU/h |
| Residential HVAC | 7.0 - 17.6 kW | 24,000 - 60,000 BTU/h |
| Commercial HVAC | 29.3 - 146.5 kW | 100,000 - 500,000 BTU/h |
| Industrial Boilers | 293+ kW | 1,000,000+ BTU/h |
Frequently Asked Questions
What is the relationship between kW and BTU?
kW measures power, while BTU measures energy. The conversion factor relates the two units for power and energy calculations.
Why is the conversion factor 3412.142?
This factor is derived from the relationship between kilowatts and BTU/h, where 1 kW = 3412.142 BTU/h.
Can I use this calculator for cooling systems?
Yes, this calculator works for both heating and cooling systems, as BTU/h is a measure of energy transfer rate.
What is the difference between BTU and BTU/h?
BTU measures energy, while BTU/h (BTU per hour) measures power. Ensure you are using the correct unit for your calculations.
How accurate is this conversion?
The conversion is highly accurate, as it uses a fixed factor based on the International System of Units (SI).
