Wh to N·m

Watt Hour

• Definition: A watt hour (Wh) is a unit of energy equivalent to one watt (1 W) of power used for one hour. It represents the total amount of energy consumed or produced over a specific time period.

• Symbol: The symbol for watt hour is Wh.

• Usage: Watt hours are commonly used to measure electrical energy consumption in homes and businesses, as well as the output of batteries and solar panels.

Newton Meter

• Definition: A newton meter (Nm) is a unit of torque that measures the rotational force applied at a distance from an axis. It is defined as the torque resulting from a force of one newton applied perpendicularly to a moment arm that is one meter long.

• Symbol: The symbol for newton meter is Nm.

• Usage: Newton meters are often used in mechanical engineering and physics to describe the torque required to turn an object.

Origin of the Watt Hour

• The watt hour originated from the combination of the watt, a unit of power, and the hour, a unit of time. The term was developed in the late 19th century as electrical systems became more prevalent, allowing for the measurement of energy consumption over time.

Origin of the Newton Meter

• The newton meter was derived from the work of Sir Isaac Newton, who formulated the laws of motion and gravitation in the 17th century. The unit itself emerged from the International System of Units (SI), where it was established as a standard measure of torque.
