What is the derivation of the word calorie?

Answer 1

CALORIE is a French word which is derived from the Latin word calor which means heat.
Technically, 1 calorie is the amount of energy required to raise the temperature of 1 gram of water 1 degree Centigrade. The calorie measure used commonly to discuss the energy content of food is actually a kilocalorie or 1000 real calories. This is the amount of energy required to raise 1 kilogram of water (about 2.2 pounds) 1 degree Centigrade.
Even when the classic definition of a calorie (actually a KILOcalorie)—a unit of energy required to raise one kilogram of water one degree Celsius—is provided, seldom is the rawhide MEANING of this definition explored. Here are some explanation of the derivation of a calorie.
The calorie, or gram calorie, is the quantity of heat required to raise the temperature of 1 gram of pure water 1°C.
The kilocalorie, or kilogram calorie, is the quantity of heat required to raise the temperature of
of pure water 1°C; it is equal to 1,000 cal.
The kilocalorie is used in dietetics for stating the heat content of a food, i.e., the amount of heat energy that the food can yield as it passes through the body; in this context, the kilocalorie is usually called simply the calorie.
The 15° calorie, or normal calorie, is widely used in chemistry and physics; it is measured by heating a 1-gram water sample from 14.5°C to 15.5°C at 1 atmosphere pressure.
The 4° calorie, also called the small calorie or therm, is measured from 3.5°C to 4.5°C (water is most dense at 3.98°C); the large calorie, or Calorie, is equivalent to 1,000 small calories.
The average value of the calorie in the range 0°C to 100°C is called the mean calorie; it is 1/100 of the energy needed to heat 1 gram of water from its melting point to its boiling point.
The 15° calorie is equivalent to 4.185 joules (J), 1.162×10-6 kilowatt-hours, 3.968×10-3 British thermal units, and 3.087 foot-pounds; the 4° calorie equals 4.204 J; and the mean calorie equals 4.190 J.

Answer 3

Wikipedia answers this nicely:

"A calorie is a unit of measurement for energy. The unit's name is French and derives from the Latin calor (heat)"

Answer 4

"Calor" is Latin for heat. Calories give us the energy to do our activities, and that generates heat.

To be very specific, a calorie is defined as the amount of heat needed to raise one gram of water by one degree C.

Answer 5

A calorie equals the amount of energy it takes our bodies to process it.'
