Instantly convert between Watts, Horsepower, BTUs, and Calories. Essential for engineers, mechanics, HVAC technicians, and physics students.
Power is the rate at which work is done or energy is transferred. Different industries use different units to measure power, from electrical systems to car engines and heating appliances.
1 Mechanical HP ≈ 745.7 Watts. 1 Metric HP ≈ 735.5 Watts. This tool uses the standard Mechanical HP.
1 kW ≈ 3412 BTU/h. This is useful for sizing generators or heating systems.
From Cars to ACs.
Need to know if a 5000 BTU air conditioner is equivalent to a 1.5 kW heater? Or comparing a 200 HP car engine to a 150 kW electric motor? This tool bridges the gap between different industry standards.
Compare specs easily.
kW (Kilowatt) is a measure of power (rate of energy use), while kWh (Kilowatt-hour) is a measure of energy (total amount used over time). This tool converts power units only.
Mechanical HP (imperial) was defined by James Watt based on lifting weight. Metric HP (PS/cv) was defined later using metric units. They are very close but not identical (1 Mech HP ≈ 1.014 Metric HP).
