    horsepower torque rpm calculator, if you know two this calculates the third. 1) What is the horsepower when an engine is producing foot pounds of torque.

    TORQUE and RPM are the MEASURED quantities of engine output. (At the bottom of this page, the derivation of that equation is shown.

    Watts is the unit of electrical power measurement and it is used to represent the power of the electrical motor. Using the example in Figure 2 above, where a constant tangential force of pounds was applied to the 12" handle rotating at RPM, we know the force involved, so to calculate power, we need the distance the handle travels per unit time , expressed as:. We're here to help. So if we plug the equivalent for FORCE from equation a and distance per minute from equation b into equation c , we get:. If that constant lb.

    How much horsepower are we talking about here? You can calculate how many foot-pounds of horsepower this engine produces using a common equation:. But where does the number 5, come from? To get from pound-feet of torque to horsepower, you need to go through a few conversions. The number 5, is the result of lumping several different conversion factors together into one number.

    The units of torque are pound-feet. So to get from torque to horsepower, you need the "per second" term. You get that by multiplying the torque by the engine speed. But engine speed is normally referred to in revolutions per minute RPM. Since we want a "per second," we need to convert RPMs to "something per second. Now what we need is a dimensionless unit for revolutions: A radian is actually a ratio of the length of an arc divided by the length of a radius, so the units of length cancel out and you're left with a dimensionless measure.

    One revolution is degrees of a circle. Since the circumference of a circle is 2 x pi x radius , there are 2-pi radians in a revolution.

    This gives us the "per second" we need to calculate horsepower. Let's put this all together. We need to get to horsepower, which is foot-pounds per second, using torque pound-feet and engine speed RPM. If we divide the foot-pounds by the 0. So if you multiply torque in pound-feet by engine speed in RPM and divide the product by 5,, RPM is converted to "radians per second" and you can get from torque to horsepower -- from "pound-feet" to "foot-pounds per second.
