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.
Milligrams
The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.
The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10-3. Milligrams can be abbreviated as mg; for example, 1 milligram can be written as 1 mg.
