Power Converter
Power measures the rate of energy transfer or work done per unit time. The SI unit is the watt (W = J/s). Power converters convert between watts, kilowatts, horsepower, BTU/hr, and calories/second.
💡
Pro Tip
Your electricity bill is in kWh (kilowatt-hours). Power (kW) × Time (hours) = Energy (kWh). A 2 kW heater running 5 hours = 10 kWh. At $0.15/kWh, that's $1.50.

Did You Know?
James Watt defined horsepower by measuring how much coal a horse could lift in a minute — 33,000 foot-pounds per minute. He intentionally set it high (actual horse output is ~0.7 hp sustained) so his steam engines could claim superiority.
