J to N·m

Joule

• Definition: A joule is a unit of energy in the International System of Units (SI) that quantifies the work done when a force of one newton moves an object one meter.

• Symbol: The symbol for joule is “J”.

• Usage: Joules are commonly used in various fields including physics, engineering, and nutrition to measure energy, work, and heat.

Newton meter

• Definition: A newton meter is a unit of torque or moment that represents the amount of force applied at a distance of one meter from a pivot point.

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

• Usage: Newton meters are used in mechanics and engineering to measure rotational forces, such as in wrenches and engine torque ratings.

Origin of the joule

• The joule is named after the English physicist James Prescott Joule, who studied the nature of heat and its relationship to mechanical work in the 19th century. His experiments laid the groundwork for the law of conservation of energy, leading to the formal adoption of the joule as a standard unit of energy.

Origin of the newton meter

• The newton meter derives its name from Sir Isaac Newton, who formulated the laws of motion and universal gravitation. The term combines Newton, the unit of force, and meter, the unit of distance, establishing a direct connection between linear movement and force application.
