N·m to MJ

newton meter

• Definition: A newton meter (Nm) 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 Nm.

• Usage: Newton meters are commonly used in engineering and physics to describe the torque applied to objects, such as turning a bolt or rotating a wheel.

megajoule

• Definition: A megajoule (MJ) is a derived unit of energy in the SI system, equal to one million joules. It is used to quantify energy, work, or heat.

• Symbol: The symbol for megajoule is MJ.

• Usage: Megajoules are often used in various fields, including physics, engineering, and energy production, to express energy consumption or generation.

Origin of the newton meter

• The newton meter is named after Sir Isaac Newton, a prominent physicist and mathematician whose work laid the foundation for classical mechanics. The unit combines the newton, a measure of force, and the meter, a measure of distance, reflecting the relationship between force and rotational movement.

Origin of the megajoule

• The term megajoule combines the prefix “mega,” meaning one million, with “joule,” named after James Prescott Joule, an English physicist known for his work on the nature of heat and energy. The joule itself is the energy transfer required to apply a force of one newton over a distance of one meter.
