Leistungsumrechner

Convert power units: watts, kilowatts, megawatts, mechanical horsepower, metric horsepower (PS), BTU per hour, foot-pounds per second and kilocalories per hour.

Die folgende Anleitung ist noch nicht auf Deutsch verfügbar und wird auf Englisch angezeigt. Der Rechner selbst ist vollständig übersetzt.

So verwenden Sie diesen Rechner

  1. Enter a power value.
  2. Choose the from and to units. Mechanical (hp) and metric (PS) horsepower differ slightly.

Formel

Power is energy per unit time; the watt is one joule per second.

1 hp (mechanical) = 745.6999 W
1 PS (metric hp) = 735.49875 W
1 BTU/h = 0.29307 W
1 ton of refrigeration = 12,000 BTU/h ≈ 3.517 kW

Examples

  1. 100 hp × 0.7457 = 74.57 kW.
  2. A 12,000 BTU/h air conditioner ≈ 3.52 kW of cooling.

Häufige Fragen

What's the difference between hp and PS?

Mechanical horsepower (US/UK) is about 745.7 W; metric horsepower (PS, CV, ch) used in Europe is about 735.5 W.

Power vs. energy?

Power is the rate of energy use. A 2 kW heater running for 3 hours uses 6 kWh of energy.

How do I size an air conditioner?

Use the BTU calculator to estimate the cooling capacity for a room.
