Kilogram

A kilogram (symbol: kg) is the base unit of mass in SI or the International System of Units. It is currently defined based on the fixed numerical value of the Planck constant, h, which is equivalent to 6.62607015 × 10-34 in the units of J·s, or kg·m2·s-1. The meter and the second are defined in terms of c, cesium frequency, and the speed of light. In spite of the fact that the definition of the kilogram was changed in 2019, the actual size of the unit remained the same. The changes were meant to enhance the definitions of SI base units, not to actually alter how the units are used throughout the world.

The name kilogram came from the French “kilogramme.”

The kilogram is the only SI base unit with an SI prefix, unlike the other base International System of Units. SI is a system founded on the meter-kilogram-second system of units.

In 1794, the kilogram was originally defined as the mass of one liter of water at its freezing point but was ultimately re-defined, since measuring the mass of a volume of water was inaccurate and cumbersome.

In 2019, based on Planck’s constant, a new definition of the kilogram was introduced and changes to the definition of the second. Before the current definition, the kilogram was expressed as being equal to the mass of a physical prototype, a cylinder made of platinum-iridium alloy, which was an insufficient measure. This is evidenced by the fact that the mass of the actual prototype for the kilogram now weighs 50 micrograms less than other copies of the standard kilogram.

The kilogram, as a base unit of SI, is used globally in nearly all applications and fields, with the exception of countries like the US, where the kilogram is used in many areas to some extent, such as industry, science, government, and the military, but typically not in everyday applications.

Pound

A pound is a unit of mass used in the imperial and United States customary systems of measurement (symbol: lb). The common pound used today, which is the international avoirdupois pound is defined as precisely 0.45359237 kilograms.

The pound descended from the Roman libra, and various definitions of the pound were used throughout history before the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the thirteenth century. In 1959, it was updated to its present form. 

The pound as a unit of weight is widely used in the US, usually for measuring body weight. Many versions of the pound existed in the past in the United Kingdom, and although the United Kingdom largely uses the International System of Units, pounds are still used within specific contexts, such as the labeling of packaged foods (by law the metric values must also be displayed). The United Kingdom also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.
