Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
