The kilogram is a **unit of measurement that serves as a constant reference for universal measuring instruments**.

The kilogram, whose symbol is kg, is one of the 7 basic units of measurement defined by the International System of Units (SI). These units serve to standardize the physical magnitudes of weights and measures around the world. The other 6 base units are: the meter (m), the second (s), the ampere (A), the Kelvin (K), the mole (mol) and the candela (cd).

Although the kilogram or kilogram is used in most countries of the world, not all have adopted the kilogram as a unit of mass/weight, such as the use of the pound in the United States and England. In this way, to know what is the equivalence of a kilogram to a pound, the conversion must be made taking into account that **1 kilogram is equal to 2.2 pounds** (1 kg=2.20462 lb).
