Torque is rotational force, measured in Newton-metres (Nm), pound-feet (lb-ft), or kilogram-metres (kg-m). 1 lb-ft = 1.356 Nm. 1 kg-m = 9.807 Nm. Car engine torque: typically 150-500 Nm. A bicycle rider produces about 50-100 Nm. A torque wrench for car wheels typically requires 100-150 Nm (or 75-110 lb-ft).

🤔 How Does This Work?
Torque = Force × Distance (perpendicular)
1 Nm = 0.7376 lb-ft = 0.10197 kg-m
1 lb-ft = 1.35582 Nm = 0.13826 kg-m
❓ Frequently Asked Questions
What is torque and why does it matter in cars?▼
Torque is rotational force — how hard an engine twists the crankshaft. High torque at low RPM makes a car feel powerful when accelerating from rest (diesel engines excel here). Horsepower is torque × RPM / 5252. For towing and hauling, torque matters more than horsepower. Sports cars prioritize high-RPM horsepower; trucks prioritize low-RPM torque.
What torque to use when tightening wheel bolts?▼
Car wheel bolts/nuts typically require 100-150 Nm (75-110 lb-ft) depending on vehicle. Check your vehicle's owner manual for the exact specification. Under-torquing risks wheels coming loose. Over-torquing can damage studs or warp brake rotors. Always use a calibrated torque wrench, not air impact gun, for final tightening.
