Kg to pound to converter

SI is a system based on the meter-kilogram-second system of units rather than a centimeter-gram-second system. This is at least in part due to the inconsistencies and lack of coherence that can arise through use of centimeter-gram-second systems, such as those between the systems of electrostatic and electromagnetic units.

The kilogram was originally defined as the mass of one liter of water at its freezing point in , but was eventually re-defined, since measuring the mass of a volume of water was imprecise and cumbersome.

A new definition of the kilogram was introduced in based on Planck's constant and changes to the definition of the second. Prior to the current definition, the kilogram was defined as being equal to the mass of a physical prototype, a cylinder made of a platinum-iridium alloy, which was an imperfect measure.

This is evidenced by the fact that the mass of the original prototype for the kilogram now weighs 50 micrograms less than other copies of the standard kilogram. Current use: As a base unit of SI, the kilogram is used globally in nearly all fields and applications, with the exception of countries like the United States, where the kilogram is used in many areas, at least to some extent such as science, industry, government, and the military but typically not in everyday applications.

Definition: A pound symbol: lb is a unit of mass used in the imperial and US customary systems of measurement.

Use this page to learn how to convert between kilograms and pounds. Type in your own numbers in the form to convert the units! You can do the reverse unit conversion from pounds to kg , or enter any two units below:. The kilogram or kilogramme, symbol: kg is the SI base unit of mass. It accepts fractional values. The kilogram kg is the SI unit of mass.

It is equal to the mass of the international prototype of the kilogram. This prototype is a platinum-iridium international prototype kept at the International Bureau of Weights and Measures.

One kg is approximately equal to 2. One pound , the international avoirdupois pound, is legally defined as exactly 0.
