Our Torque to hp Calculator will help you figure out how much power a moving item has. Because there are only a few variables between torque and horsepower, converting horsepower to torque isn’t difficult. You may also learn how to convert horsepower to torque (nm) in the text below, as well as the horsepower formula. If you know your engine’s torque, you can use this calculator to convert gross torque to horsepower!

What is horsepower? Horsepower definition
Horsepower (hp) is a unit of measurement for power, or the rate at which work is completed, generally in relation to the engine or motor output. There are a variety of horsepower specifications and kinds. The mechanical horsepower (or imperial horsepower), which is roughly 745.7 watts, and the metric horsepower, which is approximately 735.5 watts, we use these two definitions today.
Scottish engineer James Watt used the word in the late 1800s to relate the output of steam engines to the power of draft horses. Later, it was broadened to cover the output power of various types of piston engines and turbines, electric motors, and other machines. The definition of the unit differed depending on where you were. Power is currently measured in most nations using the SI unit watt. Since the adoption of EU Directive 80/181/EEC on January 1, 2010, horsepower can only be used as a supplemental unit in the EU.
What is torque? Torque definition
Torque is the rotating counterpart of linear force in physics and mechanics. Depending on the subject of study, we also know it as the moment, moment of force, rotating force, or turning effect. It denotes a force’s capacity to cause a change in the rotational motion of a body. Archimedes’ study of the use of levers gave birth to the idea. Torque is a twist of an item around a given axis, similar to how a linear force is a push or a pull. The product of the magnitude of the force and the perpendicular distance of the line of action of a force from the axis of rotation is another definition of torque.
The torque is a pseudovector in three dimensions, and it is given by the cross product of the position vector (distance vector) and the force vector for point particles. The force applied, the lever arm vector linking the point around which the torque is being measured to the point of force application, and the angle between the force and lever arm vectors determine the magnitude of torque in a rigid body.
How do we calculate horsepower?
Horsepower is much like any other power unit. It simply refers to the speed at which work is completed. This horsepower unit represents the result of a test. The goal of this experiment was to determine the power of a single horse. According to research, a horse can perform 33,000 ft-lbf of labor each minute. The formula for horsepower may be thought of as the torque delivered to an object and the speed this force generates over a particular amount of time, as we discussed in the definitions of torque, speed, and horsepower.
hp to torque formula
We calculate the link between torque, horsepower, and watts using relative values. Also, we use the conversion of horsepower to torque in a variety of electrical engineering applications. When it comes to online calculations, this horsepower to torque calculator can help you compute the equivalent torque value from an input amount of horsepower and identify the comparable torque from a given power number in watts. However, when converting gross torque to horsepower, we must first understand the Watts formula:
Power (W) = Torque (N.m) x Speed (rpm)
Because we determined our machine’s power in Watts, we can convert it to mechanical horsepower using the following formula:
Horsepower (hp(I)) = Power (W) / 745.70 W
Is speed related to horsepower?
Furthermore, the question “How fast is an item moving?” is answered by speed. The distance an item travels in a given amount of time is called speed, and it is independent of the object’s direction of motion (we know it as a scalar unit). There are two types of speed: linear (m/s, mph) and circular (rpm, rad/s).
The horsepower of an engine is the amount of power it produces. We define power as the rate at which anything does work in physics. Horsepower is a measure of how fast an automobile can go. So you’ll need more horsepower if you want to drive faster and get up to speed faster. Torque, on the other hand, is a rotating or twisting force expressed as a number. Torque is created when engines revolve around an axis in vehicles. It also may be thought of as a vehicle’s “strength.” It’s the force that propels a sports vehicle from zero to sixty in seconds while also pushing you back in your seat. It is also what propels large vehicles carrying hefty cargo.
Torque vs. hp
W measure the power of an automobile engine and expressed in a variety of units by car manufacturers. We use horsepower and torque phrases, particularly when discussing a vehicle’s acceleration. They’re a component of the mechanism that converts the energy needed to propel your automobile from the air and gasoline within the engine. Let’s take a closer look at the differences between torque and horsepower for acceleration now that we’ve got it down:
- THEY MEASURE A VARIETY OF THINGS. Simply described, torque is a unit of force measurement. It’s a measurement of the rotational force at the crankshaft of your car’s engine. The amount of power delivered from the engine to the wheels, on the other hand, we measure it in horsepower.
- FOR VEHICLE ACCELERATION, THEY WORK IN DIFFERENT MANNERS. Your car moves through a combination of torque and horsepower when you push the gas pedal. However, they each serve a different purpose in terms of assisting you in accelerating.
- FOR TOWING, TORQUE IS MORE IMPORTANT. If you move trailers, campers, boats, or anything else on a regular basis, torque is crucial for decreasing vehicle strain and pulling the weight. Torque is what helps your car start and handle hills, and it might be more potent than horsepower when it comes to keeping your engine operating smoothly under load.
- VEHICLE PERFORMANCE IS ALL ABOUT HORSEPOWER. They make high-horsepower automobiles for drivers who desire a lot of speed and power. Therefore, the greater a vehicle’s horsepower rating, expectations are the faster is to drive to its size.
- FOR FUEL EFFICIENCY, TORQUE AND HORSEPOWER ARE NOT EQUAL. If you desire a car that is as fuel-efficient as possible, the last difference between torque and horsepower may be the most crucial to you.
How to increase hp and torque?
The simplest approach to boost your car’s horsepower and torque is to tune your engine control module with a performance chip. To generate even more power, you may install a cold air intake or a larger exhaust system.
How much horsepower is torque?
Torque is calculated by multiplying horsepower by 5252 and dividing the result by the revolutions per minute. The constant is 5252 once again. When you step on the throttle, the torque is the amount of pulling power the automobile creates.
How do you convert torque to power?
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.
How much horsepower is an NM?
The unit number 2,684,519.54 N-m is equivalent to 1 hp h, or one horsepower hour. It is the EXACT same energy value as 1 horsepower hour but in the Newton meters energy unit.
