Torque Converter
Newton-meter (N·m)
Definition: The newton-meter (symbol: N·m or N m) is the SI unit of torque. One newton-meter is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one meter long.
History/origin: The unit was derived within the International System of Units (SI) by combining the unit of force (Newton) and the unit of distance (Meter). It was established to provide a scientific constant for rotational force.
Current use: It is the global standard for measuring engine torque in cars, motorcycles, and the tightening specifications for almost all modern mechanical fasteners.
Inch-pound (in·lbf)
Definition: The inch-pound force (symbol: in·lbf) is a unit of torque equal to one pound-force applied to a moment arm of one inch.
History/origin: As a smaller subdivision of the foot-pound, this unit was developed to provide higher precision for small-scale mechanical assemblies where foot-pounds resulted in fractions that were hard to read.
Current use: Used primarily for low-torque applications such as bicycle maintenance, assembling delicate electronic housings, and medical device manufacturing.

15 nm = 15 × 8.85074579 inlbf = 132.7611869 inlbf
Did You Know?
- Did you know? Torque is what gets a car moving from a standstill. While horsepower determines top speed, torque determines acceleration—or how fast you feel that "push" into your seat!
- Inch-pounds are used for delicate tasks, such as working on bicycle components, small electronics, or aerospace parts where high precision is required to avoid damaging threads.
