Calories

Converting calories is actually a conversion of energy burned by the body performing work rather than actual weight. When measuring the energy content in foods, the large calorie, or kilocalorie, is used, but it's often still just called a "calorie."

One calorie (large calorie) is equal to the heat needed to raise the temperature of one kilogram of water by 1 degree Celsius.[1] You'll need to burn 3,500 calories more than you eat to lose one pound of weight.[2]

Calories can be abbreviated as kcal; for example, 1 calorie can be written as 1 kcal.

Grams

A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.
