Torque measures rotational force. Nm is SI; ft-lbs is US automotive. Correct torque is critical for bolt tightening and engine specifications.
Torque in Automotive
Passenger car: 150–300 Nm. Heavy truck: 500–2,500 Nm. Always specified alongside RPM.
Bolt Torque Specs
M10 bolt: 40–50 Nm (30–37 ft-lbs). Over-tightening breaks bolts; under-tightening causes failures.

Applications
Automotive Maintenance
Wheel nuts: 100–120 Nm (74–89 ft-lbs). Wrong values cause wheel failure.
Mechanical Engineering
Motor/gearbox specs in Nm or ft-lbs. Convert for international components.
Bicycle Maintenance
Carbon components: 5–8 Nm. Over-tightening damages expensive parts.
Industrial Applications
Our torque converter has been used in various industrial applications such as: manufacturing equipment, conveyor systems, and robotics. For example, a machine with a 10 Nm torque output was used to power a robotic arm for assembly line production, while a 50 Nm torque output was used to drive a conveyor belt system in a food processing plant.
Frequently Asked Questions
How do you convert Nm to ft-lbs?
Divide by 1.3558. 100 Nm = 73.76 ft-lbs.
How do you convert ft-lbs to Nm?
Multiply by 1.3558. 80 ft-lbs = 108.46 Nm.
Torque vs power?
Torque = rotational force (Nm). Power = torque × angular velocity. 300 Nm at 4,000 RPM ≈ 125.7 kW.
Can I convert torque values from different units?
Yes, our torque converter can handle conversions between different units of measurement, such as Newton-meters (Nm) to foot-pounds (ft-lbs) or kilogram-meters (km/h) to horsepower (hp).
How do I convert a rotational speed to torque?
To convert rotational speed to torque, you can use the formula: torque = rotational speed x radius. For example, if the rotational speed of a wheel is 1000 revolutions per minute (RPM) and the radius of the wheel is 0.5 meters, the torque would be 500 Nm.
