Power in general is measured in Watts. But there is another unit used to calculate it. This is what we call Horse Power.It is a unit of power that is equal to 746 Watts or 33000 pound feet per minute. It is Calculated using the formula Horse Power Calculator is an easy online tool to calculate the either torque, speed or the power. You just have to enter in any of these 2 quantities and get the unknown quantity instantly.

Steps for Horsepower Calculator

Step 1 :

Read the given problem and observe the given quantities

Step 2 :

Use the power formula

Power = $\frac{\tau \times N}{5252}$

Where $\tau$ = torque

N = revolutions per minute

Substitute the values in above formula and get the answer.

Problems on Horsepower Calculator

1. A car possessing the speed of 1000 revolutions per minute has a torque of 50 pound foot. Calculate its rotating Horse power.

Step 1 :

Given: Torque $\tau$ = 50 lps, speed N = 1000 revolutions per minute

Step 2 :

The Power is given by
Power = $\frac{\tau \times N}{5252}$

= $\frac{50 \times 1000}{5252}$
= $\frac{50000}{5252}$
= 9.52 hp.

Power = 9.52 hp.

2. A bike has a torque of 100 lbs and power of 100 hp. Calculate its speed.

Step 1 :

Given: Torque $\tau$ = 50 lbs, power = 100 hp

Step 2 :

Power = $\frac{\tau \times N}{5252}$

N = $\frac{100 \times 5252}{100}$

= 5252 revolutions per minute
