Torque Calculator

Calculate torque easily using force and lever arm distance. Our Torque Calculator helps engineers and mechanics determine rotational force in seconds.

moment of force calculator:

Torque is used to measure the ability of any force to cause an object to rotate about an axis. This is made easy by the Torque Calculator that applies the formula Torque = Force x Distance. All one has to do is enter the applied force and the length of the lever arm, and get the value of torque immediately. It is needed in motor performance analysis, tightening wrenches, and rotational mechanics experiments.

mechanical torque tool Formula:

Torque Calculator is an easy-to-use tool that can be used to calculate the turning force (torque) on a rotating object. It is based on the simple physics equation of T = F x r, where T is the torque, F is the force, and r is the lever arm distance. This calculator will be important to mechanics, engineers, and physics students. Be it in tightening bolts, designing motors, or analyzing rotating systems, it gives values of accurate torque in Newton-meters (Nm), pound-feet (lbft), or other units. All you need to do is enter the force exerted and the distance perpendicular to the pivot point, and the immediate results are obtained. The instrument can be applied in automotive design and machinery setup and structural analysis, where precise torque is critical to performance and safety.

⚡ Work & Installation Input to Output:

  • Input: 1. Force (F) 2. Distance from Pivot (r) 3. Units (N·m, lb·ft, etc.)
  • Formula Used: T = F × r
  • Output: 1. Calculated Torque 2. Torque in selected unit

This ensures simple, accurate torque determination for engineering and physics applications.

Testing and Final Adjustments

Test the calculator using standard examples before ultimate deployment. As an example, the torque of a force of 20 N at 0.5 m from a pivot is 10 N. m. Check calculations with different units of N to m, lb to ft, and kg to cm to be sure that the calculations are correct. Input check to ensure that there are no negative or empty values. Modify rounding to show as many as two decimal points so as to be easier to read. Compare findings with manual values or engineering values to ensure reliability. Once validated, it can be used as an educational, industrial, or DIY calculator with consistent and correct measurements of torque.

Frequently Asked Questions - Torque Calculator:

What is torque?

Torque is the rotational force that causes an object to rotate around an axis.

What is the torque formula?

Torque = Force × Distance from pivot point.

What are the units of torque?

Newton-meter (N·m), pound-foot (lb·ft), and kilogram-centimeter (kg·cm).

What is lever arm distance?

It is the perpendicular distance between the pivot and the force line.

Can torque be negative?

Yes, depending on the rotation direction (clockwise or counterclockwise).

Is torque the same as power?

No, torque measures rotational force; power measures work per time.

Can I use this for motors?

Yes, use motor torque and speed to calculate power output.

What affects torque value?

Force magnitude and lever arm length determine torque size.

Does angle affect torque?

Yes, maximum torque occurs when the force is perpendicular to the lever.

Is this calculator free?

Yes, it’s a free online tool for physics and engineering calculations.
