F = ${F} N
r = ${r} m
θ = ${angle}°
Using Formula:
τ = F × r × sin(θ)
τ = ${F} × ${r} × sin(${angle}°)
τ = ${torque.toFixed(4)} N·m

A Torque Calculator is a scientific computational tool that accurately determines the rotational force generated when force is applied at a specific radial distance. This calculator is widely used in physics, mechanical engineering, automotive systems, construction mechanics, robotics, and biomechanics.
🚀 It eliminates manual calculation errors
📐 Provides precise SI unit outputs
🔎 Useful for students, engineers & technicians
⚡ Instant computation for force-distance-angle relationships
This tool supports calculations in Newton-meter (N·m), pound-foot (lb-ft), and kilogram-force meter (kgf·m) ensuring global usability.
Torque is everywhere. Here are real-world applications:
🔧 1. Tightening or Loosening Bolts: Using a wrench increases lever arm distance → increases torque.
🚗 2. Automobile Engines: Higher engine torque = better acceleration & pulling capacity.
🚲 3. Bicycles: Pedaling generates torque on crankshaft to rotate wheels.
🏗 4. Construction Machinery: Cranes and excavators rely on controlled torque for lifting.
🏋️ 5. Gym Equipment: Rotational joints in exercise machines depend on torque mechanics.
🚪 6. Opening Doors: Force applied at door handle produces torque around hinge.
This Torque Calculator is developed for educational, academic, and professional estimation purposes only. While every effort has been made to ensure mathematical accuracy and scientific reliability, users are advised to verify calculations independently before applying results in critical engineering, industrial, automotive, or structural operations. The tool does not replace professional engineering judgment, certified mechanical inspection, or regulatory compliance standards.
❓ What is the formula for calculating torque?
Torque is calculated using: τ = r × F × sin(θ)
Where r = distance, F = force, θ = angle.
❓ What is the SI unit of torque?
The SI unit of torque is Newton-meter (N·m).
❓ How does increasing lever arm affect torque?
Increasing the lever arm distance increases torque proportionally.
❓ Is torque the same as force?
No. Force causes linear motion, while torque causes rotational motion.
❓ Why is torque important in engines?
Torque determines rotational power output and acceleration capacity.
