- Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
- Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
- Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

## What is the relation between torque and power?

Back to Berra's theorem, torque is the capacity to do work, while power is how quickly some strenuous task can be accomplished. In other words, power is the rate of completing work (or applying torque) in a given amount of time. Mathematically, horsepower equals torque multiplied by rpm.

## How do I calculate power?

Power is equal to work divided by time.

In this example, P = 9000 J / 60 s = 150 W .

## How do you calculate power from rpm torque?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

## How do you convert torque to horsepower?

When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.

## How is torque calculated?

Torque (also called moment — mostly by engineers) is calculated by multiplying force and distance. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters).

## How do you calculate torque from Watts?

Watt (W) to Torque (Nm) Calculation:

Motor Torque T_{(}_{Nm}_{)} in Newton meter (Nm) is equal to 9.554140127times of the electric power P_{(}_{W}_{)} in watts divided by the speed N_{(}_{rpm}_{)} in rpm. Example: Calculate the rated torque can be developed by the 22000 Watts, 1490 rpm three-phase motor. T_{(}_{Nm}_{)} = 144 Nm.

## How do you calculate power in a circuit?

Electrical power is the product of voltage and current. P=VXI. P = V X I .

## How do you calculate power in watts?

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.

## How do you calculate power from speed?

Often it is convenient to calculate the average power. In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not in the same direction as the force, then the scalar product of force and velocity must be used.

## How do you calculate Nm torque from rpm and horsepower?

HP to torque (Nm) Calculation:

Torque T_{(}_{Nm}_{)} in Newton meter (Nm) is equal to the 746 times of power P_{(}_{HP}_{)} in horsepower divided by the 0.105 times of the motor speed N_{(}_{rpm}_{)} in RPM.

## How do I calculate my horsepower?

Simplify the equation for power: 1 horsepower (hp) = 550 foot-pounds / 1 second. More generally, power = force times distance, divided by time. Use the abbreviations F for "force" (pounds); D for "distance" (feet); and T for "time" (seconds), in the following general formula: P = F * D / T.

## How do you calculate motor horsepower?

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.
