Kilocalorie (It)/minute
A unit of power representing the energy expended or transferred at a rate of one kilocalorie per minute.
History/Origin
The kilocalorie (kcal) has historically been used to measure energy in food and nutrition, while the minute as a time unit has been standard in timekeeping. Combining these, kcal/min was used to quantify power, especially in contexts like metabolic rates and energy expenditure, before the widespread adoption of the watt as the SI unit of power.
Current Use
The kcal/min is primarily used in fields such as physiology and sports science to express rates of energy expenditure, though it is less common today with the adoption of the watt (W) as the standard SI unit of power.
Terawatt
A terawatt (TW) is a unit of power equal to one trillion watts (10^12 watts).
History/Origin
The term 'terawatt' was introduced as part of the metric system to quantify extremely large power levels, especially in fields like astrophysics and energy production, gaining prominence in the 20th century with advancements in large-scale energy and power measurement.
Current Use
Terawatts are used to describe the total power output of large-scale energy sources, such as the total global power consumption, solar radiation received by Earth, and astrophysical phenomena.
