Convert Pound to Milligram
Please provide values below to convert pound [lbs] to milligram [mg], or vice versa.
Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The avoirdupois pound is equivalent to 16 avoirdupois ounces.
History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the 13th century. It was updated to its current form in 1959. It is a system that was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.
Current use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.
Definition: A milligram is a unit of weight and mass that is based on the SI (International System of Units) base unit of mass, the kilogram. It is equal to 1/1,000 grams, or 1/1,000,000 kilograms.
History/origin: The milligram is based on the SI unit of weight and mass, the kilogram. As an SI unit, it uses the "milli" SI prefix to denote that it is a submultiple of the base unit. Although the "milli" prefix denotes a submultiple with respect to the gram, the kilogram, not the gram, is technically the SI base unit of mass.
Current use: As a submultiple of an SI base unit, the milligram is widely used in many applications, from everyday use to measure the weight or mass of foods, substances, etc., to widespread use in scientific labs, among other areas.
