N·m to Wh

newton meter

• Definition: A newton meter (Nm) is a unit of torque or moment of force, 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 commonly used in mechanics and engineering to quantify the rotational effect of a force applied to an object. This unit is crucial in applications such as measuring the torque applied by engines and machinery.

watt hour

• Definition: A watt hour (Wh) is a unit of energy equivalent to one watt of power used for one hour. It measures the amount of energy transferred or consumed over a period of time.

• Symbol: The symbol for watt hour is Wh.

• Usage: Watt hours are frequently used in electricity billing and energy consumption measurements, indicating how much energy is used by electrical devices over time.

Origin of the newton meter

• The newton meter is named after Sir Isaac Newton, who formulated the laws of motion and universal gravitation. The unit combines the newton, which measures force, and the meter, which measures distance, thus representing torque as a product of force and distance.

Origin of the watt hour

• The watt hour has its origins in the relationship between power and energy. The watt is a measure of power named after James Watt, a Scottish inventor and mechanical engineer. The watt hour reflects the energy consumed if a device operates at one watt for one hour.
