Unit Explanations
Horsepowerhp
Source UnitHorsepower is a unit of measurement for power, which quantifies the rate at which work is done. It is traditionally used to express the power output of engines or motors. One horsepower is defined as the power needed to lift 550 pounds one foot in one second, equivalent to 745.7 watts in the SI system. The term was originally formulated to compare the output of steam engines with the power of draft horses, which were a primary source of industrial power in the 18th century.
Current Use
Horsepower remains a common unit of power measurement in the automotive industry, where it is used to specify the power output of engines. It is also used in various other industries, such as those involving pumps, turbines, and electric motors. Despite the widespread adoption of the watt as the SI unit of power, horsepower is still frequently used in non-SI contexts, particularly in the United States and the United Kingdom.
Fun Fact
James Watt's first estimate of horsepower was based on the power of a brewery horse.
Newton Meter SecondNm·s
Target UnitThe Newton meter second (Nm·s) is a derived unit of power in the International System of Units (SI), representing the product of force (in newtons) and distance (in meters) multiplied by time (in seconds). This unit encapsulates the work done per unit of time when the force is exerted over a distance. In essence, it measures the rate at which work is done or energy is transferred. One Newton meter second is equivalent to one watt multiplied by one second, highlighting its relation to both mechanical power and energy.
Current Use
The Newton meter second is used primarily in engineering and physics to quantify power and work done over time. It is commonly applied in mechanical engineering, electrical engineering, and various fields involving dynamics and energy transfer. Its relevance spans from calculating the power output of engines to analyzing mechanical systems in research and development labs.
Fun Fact
The watt, a unit of power, is defined as one joule per second, which is equivalent to one Newton meter second.

Definition
Horsepower is a unit of measurement for power, which quantifies the rate at which work is done. It is traditionally used to express the power output of engines or motors. One horsepower is defined as the power needed to lift 550 pounds one foot in one second, equivalent to 745.7 watts in the SI system. The term was originally formulated to compare the output of steam engines with the power of draft horses, which were a primary source of industrial power in the 18th century.
History & Origin
The concept of horsepower was introduced in the late 18th century by the Scottish engineer James Watt to help market his steam engines. Watt observed the performance of horses in coal mines and estimated that a horse could turn a mill wheel of a certain size at a certain speed. This observation led him to define one horsepower as the ability to lift 550 pounds one foot in one second. Watt's definition was widely adopted and became a standard measure of engine power.
Etymology: The term 'horsepower' combines 'horse' with 'power', reflecting its origin as a measure of mechanical power compared to the power of a horse.
Current Use
Horsepower remains a common unit of power measurement in the automotive industry, where it is used to specify the power output of engines. It is also used in various other industries, such as those involving pumps, turbines, and electric motors. Despite the widespread adoption of the watt as the SI unit of power, horsepower is still frequently used in non-SI contexts, particularly in the United States and the United Kingdom.

Newton Meter Second
power • Non-SI
Definition
The Newton meter second (Nm·s) is a derived unit of power in the International System of Units (SI), representing the product of force (in newtons) and distance (in meters) multiplied by time (in seconds). This unit encapsulates the work done per unit of time when the force is exerted over a distance. In essence, it measures the rate at which work is done or energy is transferred. One Newton meter second is equivalent to one watt multiplied by one second, highlighting its relation to both mechanical power and energy.
History & Origin
The Newton meter second is derived from the SI units of force (newton), distance (meter), and time (second). The newton itself is named after Sir Isaac Newton, who made significant contributions to classical mechanics. This unit has been formalized in the context of the SI system, which was established in the late 1960s to standardize measurements across various fields of science and engineering. The use of Nm·s as a unit of power reflects the integration of these foundational concepts in physics.
Etymology: Named after Sir Isaac Newton, whose laws of motion form the foundation of classical mechanics, and the meter and second are standard units of distance and time, respectively.
Current Use
The Newton meter second is used primarily in engineering and physics to quantify power and work done over time. It is commonly applied in mechanical engineering, electrical engineering, and various fields involving dynamics and energy transfer. Its relevance spans from calculating the power output of engines to analyzing mechanical systems in research and development labs.
💡 Fun Facts
- •The watt, a unit of power, is defined as one joule per second, which is equivalent to one Newton meter second.
- •Newton meter second is often used in engineering calculations relating to the efficiency of machines and engines.
- •The unit can also describe angular momentum, as torque (in Nm) multiplied by time can reflect rotational power.
