Power Converter (Watt, Kilowatt, Horsepower, BTU/h)
About Power Converter (Watt, Kilowatt, Horsepower, BTU/h)
The Power Converter helps you instantly convert between common power units — watts (W), kilowatts (kW), horsepower (HP), and BTU per hour (BTU/h). It’s a must-have tool for engineers, electricians, HVAC professionals, and students dealing with energy and power calculations.
Conversion Formulas (Simplified)›
1 kW = 1000 W 1 HP = 745.7 W 1 BTU/h = 0.2931 W
These relationships help you convert between electrical, mechanical, and thermal power units. For example, 1 kilowatt equals 1.341 horsepower, and 1 horsepower equals 2544.43 BTU/h.
Example:
Input: Convert 5 horsepower (HP) to kilowatts (kW)
Output: 5 HP × 0.7457 = 3.7285 kW
Steps to Use:
- Enter the value of power you want to convert.
- Select the unit you are converting from (W, kW, HP, or BTU/h).
- Choose the target unit you want to convert to.
- Click 'Calculate' to get the equivalent power in the desired unit.
Frequently Asked Questions
What is power conversion?›
Power conversion means changing a power value from one unit to another — for example, converting mechanical power (horsepower) into electrical power (watts or kilowatts).
How many watts are there in one horsepower?›
1 horsepower equals approximately 745.7 watts (W).
How do I convert kilowatts to BTU/h?›
Multiply the value in kilowatts by 3412.14 to get BTU/h. For example, 2 kW = 6824.28 BTU/h.
What is the difference between watts and horsepower?›
Watts measure electrical power, while horsepower measures mechanical power. Both express the rate of energy transfer but in different systems.
Is this calculator suitable for HVAC and industrial use?›
Yes. The converter is accurate for heating, cooling, and mechanical energy applications in HVAC, automotive, and industrial systems.
