Torque Calculator
Calculate torque with our free torque calculator. Find the rotational force in newton-meters or pound-feet using force, lever arm, and angle values.
Step 1: Input Parameters
Understanding Torque
Torque is the rotational equivalent of linear force. It measures how much a force acting on an object causes that object to rotate. The pivot point is the point about which the object rotates.
Step 2: How to Calculate Torque
The torque formula is:
Where:
- τ = Torque (N·m or lbf·ft)
- r = Lever arm distance
- F = Force applied
- θ = Angle between force and lever arm
Example Calculation
If you apply a force of 120 N at the end of a 0.5 m wrench at a 90° angle:
τ = 0.5 × 120 × sin(90°) = 60 N·m
Practical Applications
Torque calculations are essential in engineering, automotive applications (engine torque), construction, and everyday tasks like using wrenches or opening doors.
