What is Power Converter?

The Power Converter is a utility for translating the rate at which work is done or energy is transmitted. Unlike Energy (which measures total volume), Power measures Energy over Time (e.g., Joules per second). It easily translates automotive engine specs like Horsepower (HP) into standard electrical Kilowatts (kW) or HVAC system BTU/h ratings.

When to use?

  • Car enthusiasts comparing European electric vehicle ratings (kW) to traditional combustion engine car specs (HP)
  • Electricians translating the cooling power of a commercial AC unit from BTU/h into baseline Watts (W)
  • Professional cyclists converting their exact pedaling power from mechanical Watts into Calories per second

Frequently Asked Questions

Is Horsepower (HP) actually the strength of one horse?

Historically, yes! James Watt coined the term in the 18th century to compare the output of his steam engines with the draft horses used to pull coal. Today, one exact Mechanical Horsepower (Imperial) is defined as exactly 745.7 Watts.

What is the difference between Imperial HP and Metric HP (PS/CV)?

They are slightly different. Imperial Horsepower (HP) equals 745.7 Watts. However, European manufacturers typically use Metric Horsepower (denoted as PS in Germany or CV in France), which equals exactly 735.5 Watts. Our tool supports both formats for accurate car spec comparisons.

What is the difference between a Kilowatt (kW) and a Kilowatt-hour (kWh)?

Kilowatts (kW) measure POWER — the instantaneous rate at which a machine uses energy. Kilowatt-hours (kWh) measure ENERGY — the total amount consumed over time. For example, if you run a 2 kW heater continuously for 3 hours, you will consume total of 6 kWh of energy on your electric bill.
