Kilograms to Pounds

The Kilogram

The Kilogram, abbreviated as either kg. or the kilo (informally) is a unit of mass and in a non-stricter and non-scientific sense, a unit of weight. The unit is used globally and is considered to be one of the base units of the SI system of international measurements of units. While on a daily basis, the usage of the kilogram is accepted in terms of weight of an object, in the SI unit system, the kilogram is the base unit for mass.

As per the definition, a kilogram is the exact mass of a prototype block of platinum-iridium. This prototype is sealed and stored in France, at the International Bureau of Weights and Measures. The prototype was manufactured way back in 1889.

Of all the SI units, the kilogram is the only unit which is defined on the basis of a physical object rather than on the basis of a fundamental physical property.

Also, the kilogram is equivalent to a thousand grams. Earlier known as the grave, the kilogram was later used to refer to define a thousand grams. When the metric system of measurement was introduced, the gram was found to be an impractical measure for most purposes and the kilogram was derived in order to serve as a much more practical unit and soon began to be accepted as a base unit. This was later also adopted by the SI system of units in 1960.

In terms of common reference, a kilogram represents approximately the weight of a liter of water or a typical full sized basketball. All across the world, the kilogram is commonly used as a measure of mass and weight on an everyday basis.

The Pound

The Pound, abbreviated as either lb. or lbm is a unit of mass and informally a unit of weight. The unit is commonly used across some countries of the world such as the UK, the USA, Canada, Australia, New Zealand and a few others. As used in the imperial system, a pound is accepted as a measure of mass or weight and is defined as being equivalent to approximately 453.59 grams.

The origin of the term refers to the weight of the Roman Libraand the term pound is an adaptation of the phrase Libra Pondo in Latin. Throughout the course of history, the exact mass of the pound has however, varied from one system to another across different countries. Largely, the value of the pound lies in between 350 to 560 grams across different systems.

In common English speaking countries, a person’s weight or food is measured in terms of pounds. One pound is also said to consist of sixteen ounces and the pound has also been historically used to refer to the weight of ammunition or weaponry that would be used in warfare. Pound per square inch is a unit of pressure which is used across the UK and the US.
