Calorie

Dr. Kennedy
A “calorie” is a unit of food energy. In nutrition terms,
the word calorie is used instead of the more precise scientific term kilocalorie
which represents the amount of energy required to raise the temperature of a
liter of water one degree centigrade at sea level. The common usage of the word
calorie of food energy is understood to refer to a kilocalorie and actually
represents, therefore, 1000 true calories of energy. The technical definition
of “calorie” is A calorie is the amount of energy required to raise
the temperature of one cc (cubic centimeter) of water (by definition one gram)
one degree centigrade at sea level; also known as cal, gram calorie,
or small calorie.
