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.
CentiwattcW
Target UnitThe centiwatt (cW) is a derived metric unit of power, defined as one hundredth (1/100) of a watt. It is part of the International System of Units (SI) and is used primarily to express small power levels. Power, in physics, is the rate at which energy is transferred or converted. Therefore, 1 centiwatt equals 0.01 watts. The use of centiwatts allows for more precise measurements in applications where watt measurements may be too coarse, making it particularly useful in electronics and low-power devices.
Current Use
Centiwatts are predominantly used in the fields of electronics, renewable energy, and telecommunications. As devices become more energy-efficient, measuring power in centiwatts allows for better control and management of energy consumption. For example, small electronic components, such as sensors and low-power microcontrollers, often list their power requirements in centiwatts. This unit is also useful in assessing the output of small solar panels and energy harvesting technologies.
Fun Fact
The centiwatt is often used in discussions about energy efficiency, particularly in the context of low-power devices.

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.
💡 Fun Facts

power • Non-SI
Definition
The centiwatt (cW) is a derived metric unit of power, defined as one hundredth (1/100) of a watt.

Therefore, 1 centiwatt equals 0.01 watts. The use of centiwatts allows for more precise measurements in applications where watt measurements may be too coarse, making it particularly useful in electronics and low-power devices.
History & Origin
The centiwatt has its origins in the metric system, which was developed in France during the late 18th century. The metric system was designed to create a standardized set of units for measurements, including length, mass, and volume. The watt, named after Scottish inventor James Watt, was adopted as a unit of power in 1889. The centiwatt, as a subdivision, was introduced to allow for more granularity in measuring small power outputs, particularly in emerging technologies in the late 20th century.
Etymology: The term 'centi' comes from the Latin 'centum,' meaning hundred. Therefore, 'centiwatt' literally translates to 'one-hundredth of a watt.'
Current Use
Centiwatts are predominantly used in the fields of electronics, renewable energy, and telecommunications. As devices become more energy-efficient, measuring power in centiwatts allows for better control and management of energy consumption. For example, small electronic components, such as sensors and low-power microcontrollers, often list their power requirements in centiwatts.

💡 Fun Facts
- •The centiwatt is often used in discussions about energy efficiency, particularly in the context of low-power devices.
- •The concept of centiwatts emerged as compact electronics became ubiquitous in everyday life.
- •In the context of solar panels, the output can be measured in centiwatts to reflect small changes in energy production.
