Frequently Asked Questions
What is a watt in power measurement?
A watt (W) is the SI unit of power, representing one joule per second. It measures the rate at which energy is transferred or converted.
How many kilowatts in a megawatt?
One megawatt (MW) equals 1,000 kilowatts (kW), which equals 1,000,000 watts (W). The metric system uses powers of 10 for easy conversion.
What is the difference between hp and PS?
Mechanical horsepower (hp) equals 745.7 watts, while metric horsepower (PS, Pferdestärke) equals 735.5 watts. PS is slightly weaker than hp.
How do I convert BTU/h to watts?
One BTU/h equals approximately 0.293071 watts. This is useful for converting HVAC and refrigeration capacities.
