What is Torque?

Torque (or moment of force) is the rotational equivalent of linear force. It measures how much a force causes an object to rotate around an axis.

τ = F × r × sin(θ)
Force × distance × sin of angle

🔧 SI Unit: Newton-meter (N·m)

🇺🇸 Imperial: Pound-foot (lb·ft)

⚡ Not the same as energy (Joule)

🔩 Critical for bolt tightening specs

About Torque Conversion

Automotive Use

Torque is fundamental in automotive engineering. Engine output is measured in N·m or lb·ft. Lug nut torque specs prevent over/under-tightening. A torque wrench ensures precise fastening.

N·m vs lb·ft

Newton-meters (N·m) are the SI standard used globally. Pound-feet (lb·ft) are common in the US. Quick rule of thumb: multiply N·m by 0.74 to get lb·ft, or lb·ft by 1.36 for N·m.

Torque vs Power

Torque is the rotational force, while power (watts/horsepower) is how fast that force is applied. Power = Torque × Angular Velocity. Both matter for engine performance.

Precision Matters

In aerospace, medical devices, and electronics, torque specs are critical. Over-tightening can strip threads or crack components. Under-tightening causes dangerous loose connections.
