Power Converter FAQ
What is a power converter?
A power converter converts power units such as W, kW, hp, and BTU/h. It is useful for electrical systems, engines, appliances, HVAC, machinery, and energy comparisons.
How do I convert watts to kilowatts?
Enter a value, choose W as the source unit, and choose kW as the target unit. Since 1 kW = 1000 W, this is common for appliances, electrical loads, and energy-use estimates.
How do I convert horsepower to watts?
Enter the value, select hp as the source unit, and select W as the target unit. This is useful when comparing engine power, motor ratings, machinery specs, and electrical equivalents.
What is the difference between W, kW, hp, and BTU/h?W and kW are metric power units, hp is commonly used for engines and motors, and BTU/h is often used for heating, cooling, and HVAC equipment.
Is power the same as energy?
No. Power measures how quickly energy is used or produced, usually in W or kW. Energy measures the total amount used or produced, such as J or kWh.
When should I use a power converter?
Use a power converter when comparing appliance ratings, motor output, engine horsepower, HVAC capacity, electrical loads, generator size, machinery specs, or power values shown in different unit systems.
Can I use this converter for engines, appliances, and HVAC?
Yes. This power converter is useful for engine horsepower, electric motors, appliances, heaters, air conditioners, HVAC systems, generators, and machinery power comparisons.
