Unit Definitions

What is a Horsepower (HP)?

ImperialUnited States, United Kingdom

Horsepower (HP) is a unit of measurement for power, originally developed to compare the output of steam engines with horse power.

History

The term 'horsepower' was coined by James Watt in the late 18th century to market his steam engines. It was based on the amount of work a horse could perform in a given time.

Current Use

Today, horsepower is widely used to measure the power of engines in cars, motorcycles, and various machinery.

What is a Calorie per Second (cal/s)?

Metric (SI)Worldwide

A calorie per second (cal/s) is a unit of power that represents the rate at which energy is expended or transferred, specifically in terms of calories.

History

The calorie was originally defined in the 19th century as the amount of heat required to raise the temperature of one gram of water by one degree Celsius, relating to thermal energy.

Current Use

Calorie per second is commonly used in fields such as nutrition and exercise science to measure energy expenditure during physical activity.
