Convert gram to milligram
gram
Definition: A gram (symbol: g) is a unit of mass in the International System of Units (SI). The definition of the gram is based on the kilogram, where a gram is one thousandth of a kilogram, the SI base unit of mass. Since 2019, the definition of the kilogram is no longer based on the international prototype, and rather is based on Planck's constant, h, along with the new definitions of the second and the meter.
History/origin: Originally, a gram was defined as the absolute weight of pure water in a cubic centimeter at the temperature of melting ice (later 4 °C). The gram used to be a fundamental unit of mass as part of centimeter-gram-second systems of units up until the widespread adoption of SI, which uses kilograms as the base unit of mass. The gram was later redefined as one thousandth of a kilogram, the SI (meter-kilogram-second system of units) base unit of mass.
Current use: The gram is widely used in every life as well as scientific contexts. For example, the gram is typically used to measure non-liquid ingredients used for cooking or groceries. Standards on the nutrition labels of food products often require the relative contents to be stated per 100 grams of the product.
milligram
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.
