What Is a Kilogram?

One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.

The formal definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[1] It is equal to the mass of 1,000 cubic centimeters, or milliliters, of water.

The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.

What Is a Calorie?

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.[2] You'll need to burn 3,500 calories more than you eat to lose one pound of weight.[3]

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