Attowatt
An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.
History/Origin
The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.
Current Use
The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
