Torque Calculator

The Torque Calculator allows users to compute the torque in various units including Newton-meters, pound-feet, and kilogram-force meters based on inputs of force, lever arm length, and the angle between them.

Using the Torque Calculator

The Torque Calculator is designed to help you calculate the torque produced by a force applied at a distance from a pivot point. Follow these steps to correctly use the calculator and obtain an accurate result.

Step 1: Input the Force Value

Begin by entering the magnitude of the force in the Force (F) field. Ensure the value is non-negative and precise, using up to two decimal places. The force represents the physical push or pull applied to the lever.

Step 2: Select the Force Unit

  • From the Force Unit dropdown, select the appropriate unit for your force value.
  • Options available include:
    • Newtons (N) – Standard metric unit.
    • Pound-force (lbf) – Imperial unit commonly used in the United States.
    • Kilogram-force (kgf) – Alternative metric unit sometimes used in engineering.

Step 3: Input the Radius or Lever Arm Length

Enter the distance from the pivot point to the point where the force is applied in the Radius/Lever Arm Length (r) field. Make sure this value is accurate and expressed to two decimal places if necessary. The radius is crucial in determining the torque.

Step 4: Select the Length Unit

  • Use the Length Unit dropdown to choose the corresponding unit for your radius value.
  • The available units are:
    • Meters (m) – Standard metric measurement.
    • Inches (in) – Commonly used in various regions, mostly in the US.
    • Feet (ft) – Another imperial unit for longer lengths.

Step 5: Enter the Angle

In the Angle between Force and Radius (θ) field, enter the angle in degrees between the direction of the force and the lever arm. This should be within 0 to 360 degrees and as precise as possible, to one decimal place. This angle is critical as it affects the effectiveness of the force.

Step 6: Review the Calculated Torque

Once all inputs are provided, the calculator will output the torque in various units:

  • Torque (N⋅m): The standard torque measurement in the metric system.
  • Torque (lb⋅ft): Torque measurement in the imperial system.
  • Torque (kgf⋅m): An alternative metric system unit.

Each result is presented with two decimal places for precision along with its unit. Make sure to interpret the results accordingly, using the appropriate unit that fits your context.
