Embed this torque calculator on your website for free. It's responsive, always up-to-date, and easy to customize.
Enter Force and Distance (angle is optional, defaults to 90°)
Angle between force and lever arm (0-90°). Default is 90° for perpendicular force.
Torque (τ) is rotational force - it causes objects to rotate around an axis. The effectiveness depends on:
Select whether to calculate torque, force, or distance based on what values you know.
Input the measured values for force, distance, and angle of application.
Enter the angle between force direction and lever arm (90° for perpendicular force).
The calculator applies τ = F × r × sin(θ) to find the torque value.
Interpret the torque result for your mechanical system design.
Suitable for small fasteners, precision instruments, and light-duty applications. Common in electronics and small machinery.
Typical for automotive applications, medium-sized bolts, and general mechanical systems. Most hand tools operate in this range.
Heavy-duty applications like large automotive components, industrial machinery, and structural connections.
Industrial applications requiring specialized tools. Common in heavy machinery, large engines, and structural steel connections.
Relate torque, force, lever arm, and application angle. Helpful for wrenching, machinery, and design checks.
Convert between torque, power, and speed. Compute moment from force and lever arm.
τ = F × r and unit conversions.
P = τ × ω (with RPM).
N·m, lb·ft, kW, hp ready.

Important: This torque calculator is designed for educational and preliminary mechanical analysis purposes using fundamental torque relationships and idealized rigid-body mechanics. While calculations are mathematically accurate for basic torque applications, real-world mechanical systems involve complex factors including material deformation, friction, dynamic loading, safety factors, and specific application requirements that are not captured by simplified torque formulas. For mechanical design, fastener selection, equipment specification, or any application involving safety-critical torque requirements, always follow manufacturer specifications, applicable safety standards, and consult qualified mechanical engineers who can account for the specific loading conditions, safety margins, and regulatory requirements of your mechanical application.
