Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
Ton-Hour (Refrigeration)
A ton-hour (ton*h) is a unit of energy representing the amount of cooling provided by one ton of refrigeration over one hour.
History/Origin
The ton-hour originated from the refrigeration industry, where the 'ton' is a unit of cooling capacity, and the hour indicates the duration. It has been used historically to quantify cooling energy consumption and capacity.
Current Use
Today, the ton-hour is used in HVAC and refrigeration systems to measure cooling energy consumption, system capacity, and performance over specific periods.
