What is Power?

Power is the rate at which energy is transferred or converted. It measures how quickly work is done or how fast energy is consumed or produced. In practical terms, power determines how much energy an appliance, motor, or system uses over time.

Common Power Units

  • Watt (W): The SI unit of power. Defined as one joule per second.
  • Kilowatt (kW): 1,000 watts. Commonly used for household appliances and energy bills.
  • Megawatt (MW): 1,000,000 watts. Used for large-scale power generation plants.
  • Horsepower (hp): A unit used mainly in the automotive and mechanical industries. 1 hp ≈ 745.7 watts.
  • BTU/hr: British Thermal Units per hour, used in HVAC and heating systems.
  • dBm and dBW: Decibel units used in electrical and radio transmission power.

Why Use a Power Conversion Calculator?

  • Engineering: Convert between mechanical and electrical power units in industrial designs.
  • HVAC: Calculate heating and cooling capacity using BTU/hr and kilowatts.
  • Automotive: Convert engine output between horsepower and kilowatts.
  • Electronics: Compare signal power levels using decibel scales.
  • Energy Management: Evaluate power usage, cost, and performance across regions.

Conversion Formulas

  • 1 kW = 1,000 W
  • 1 MW = 1,000,000 W
  • 1 hp = 745.7 W (mechanical), 735.5 W (metric)
  • 1 BTU/hr = 0.293071 W
  • 1 dBW = 10 × log10(Power in W)
  • 1 dBm = 10 × log10(Power in mW)

FAQs

Q: What is the most commonly used unit of power?
The watt (W) is the standard SI unit for power and is widely used globally.

Q: Can this calculator be used for three-phase power?
Yes, but you must calculate total power using three-phase formulas before converting the value.

Q: Are mechanical and electrical horsepower the same?
No. Mechanical hp is ≈ 745.7 W, while metric hp is ≈ 735.5 W.

Q: What is BTU/hr?
It’s a unit of power used to describe the output of heating and cooling systems.

Q: Can I convert between dBm and Watts?
Yes, using logarithmic equations. This calculator supports those conversions as well.

Advanced Use Scenarios

  • Data Centers: Track energy load across servers and equipment using kilowatts.
