Unit Explanations
WattW
Source UnitThe watt (symbol: W) is the SI unit of power, defined as the rate of energy transfer equivalent to one joule per second. It measures the amount of energy conversion or transfer that occurs per unit time. In practical terms, it quantifies the rate at which work is done or energy is consumed. The watt is a derived unit in the International System of Units (SI), and it is used extensively in various fields such as electricity, mechanics, and thermodynamics to quantify power output or consumption.
Current Use
The watt is widely used across the globe to measure electrical power, mechanical power, and heat transfer. It serves as a fundamental unit in the fields of electrical engineering, physics, and many applied sciences. It is crucial for calculating energy consumption in households, industries, and for determining the power output of engines and machinery.
Fun Fact
One watt is equivalent to 1/746th of a horsepower.
Horsepower (Water)hp(w)
Target UnitHorsepower (water), denoted as hp(w), is a unit of power defined specifically in relation to water, notably in terms of pumping applications. It is commonly accepted that one horsepower (water) is equivalent to 550 foot-pounds per second or approximately 745.7 watts. This measurement reflects the power required to lift water at a specific rate, which is particularly relevant in hydraulic engineering and water management. Thus, horsepower (water) is not just a measure of energy conversion but also incorporates the efficiency of hydraulic systems and the gravitational force acting on water.
Current Use
Today, horsepower (water) is widely used in various industries, particularly in hydraulic engineering, where it serves as a benchmark for evaluating the power of pumps and turbines. It is especially relevant in sectors like agriculture, municipal water supply, and wastewater treatment, where the movement of water is critical. The unit is primarily utilized in the United States and other countries that still employ imperial units for engineering and technical specifications.
Fun Fact
The original horsepower calculation by James Watt was based on the ability of horses to turn a mill wheel.

Definition
Horsepower (water), denoted as hp(w), is a unit of power defined specifically in relation to water, notably in terms of pumping applications. It is commonly accepted that one horsepower (water) is equivalent to 550 foot-pounds per second or approximately 745.7 watts. This measurement reflects the power required to lift water at a specific rate, which is particularly relevant in hydraulic engineering and water management. Thus, horsepower (water) is not just a measure of energy conversion but also incorporates the efficiency of hydraulic systems and the gravitational force acting on water.
History & Origin
The concept of horsepower was developed in the late 18th century by James Watt, a Scottish inventor and mechanical engineer. Watt sought to quantify the power output of steam engines in a way that was relatable to the work done by horses, which were commonly used for labor at that time. To make his steam engines more appealing, he introduced horsepower as a measurement, which eventually led to the specific definition for water pumping applications based on the amount of water lifted.
Etymology: The term 'horsepower' is derived from the power that a horse can exert, specifically a measure of work against resistance over time.
