¿Qué son los caballos de fuerza?

Horsepower (HP) is a unit of power that measures the rate at which work is done. It was defined by James Watt to compare steam engines with draft horses. One mechanical horsepower equals 745.7 watts or 0.7457 kilowatts. Horsepower is the standard power rating for car engines, electric motors, and industrial machinery worldwide.

All Formulas at a Glance

HP from Torque: HP = (Torque × RPM) / 5252

Torque from HP: Torque = (HP × 5252) / RPM

RPM from HP: RPM = (HP × 5252) / Torque

Conversiones: 1 HP = 745.7 W = 0.7457 kW

¿Por qué 5252?

The constant 5252 comes from unit conversions. One horsepower is 550 ft-lb per second. To go from RPM to radians per minute: (550 × 60) / (2π) ≈ 5252. This means horsepower and torque curves always cross at 5252 RPM when plotted on the same graph.

Key Conversion Factors

• 1 HP = 745,7 vatios = 0,7457 kW

• 1 kW = 1,341 CV = 1000 vatios

• 1 pie-libra = 1,3558 N·m

• 1 N·m = 0,7376 pies-libra

Quick Examples

• 300 pies-libra a 5252 RPM → (300 × 5252) / 5252 = 300 HP

• 200 HP a 6000 RPM → (200 × 5252) / 6000 = 175,07 ft-lb

• 150 CV = 111,86 kW = 111.855 W

Notas importantes

  • Todos los valores de par y potencia deben ser mayores que cero.
  • HP = (Torque × RPM) / 5252 applies only to rotational power in imperial units.
  • Newton-meter inputs are automatically converted to ft-lb for the formula.
  • Estos son valores de caballos de fuerza mecánicos (frenos). Existen otras definiciones de HP (HP métrico, HP eléctrico).
