N·m to ft·lb

newton meter

• Definition: A newton meter is a unit of torque in the International System of Units (SI). It measures the rotational force applied at a distance from a pivot point.

• Symbol: The symbol for newton meter is N·m.

• Usage: Newton meters are commonly used in engineering and physics to quantify rotational forces, such as those applied by wrenches or motors.

foot pound

• Definition: A foot pound is a unit of torque that represents the force of one pound applied at a distance of one foot from a pivot point.

• Symbol: The symbol for foot pound is ft·lb or lb·ft.

• Usage: Foot pounds are often used in the United States in mechanical and automotive contexts to describe the torque specifications of engines and tools.

Origin of the newton meter

• The newton meter was named after Sir Isaac Newton, an influential physicist and mathematician who formulated the laws of motion and universal gravitation. It was adopted as a unit of torque in the metric system, which was developed in France in the late 18th century as part of efforts to standardize measurements.

Origin of the foot pound

• The foot pound has its origins in English units of measure, which date back to the medieval period. The term “foot” refers to the length measurement, while “pound” refers to the weight measurement. The foot pound became widely used in the United States and other countries that adopted the imperial system.
