Milligrams: A Unit of WeightMilligrams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Milligrams are derived from the Latin word mille, which means thousand, and the French word gramme, which means weight. The symbol for milligram is mg. Definition of the MilligramThe milligram is defined as one onethousandth of a gram, which is one onemillionth of a kilogram, which is the base unit of mass in the SI. The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the meter and the second are defined in terms of c and ∆ν Cs. The Planck constant is a fundamental physical constant that relates the energy of a photon to its frequency. The milligram is a very small unit of weight, equivalent to about 0.000035 ounces or 0.000002 pounds. It is commonly used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms. How to Convert MilligramsMilligrams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert milligrams to other units of weight in the US customary system and the SI system:

Pounds: A Unit of WeightDefinition of the PoundA pound is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to 0.45359237 kilograms, or 16 ounces, or 7000 grains. One pound can also be written as lb or lbs. History of the PoundThe pound was originally defined in ancient Rome as the mass of a bronze bar called a libra, which was divided into 12 ounces. The libra was later adopted by various regions and countries in Europe, such as England, France and Germany, with different values and subdivisions. The pound as we know it today is based on the avoirdupois system, which was developed in the 13th century in France and England. The avoirdupois pound was standardized in 1959 by an international agreement among the United States, Canada, Australia, New Zealand and South Africa as exactly 0.45359237 kilograms. The pound, as well as other units of weight, such as the ounce and the ton, were introduced in the 19th century as part of the imperial system of measurement that aimed to unify the units used in the British Empire. The pound was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units. How to Convert PoundsTo convert pounds to other units of weight, we need to use conversion factors that relate the pound to the desired unit. For example, to convert pounds to kilograms, we need to know that one kilogram is equal to 2.2046226218 pounds. Therefore, one pound is equal to 0.45359237 kilograms. Here are some common conversion factors for pounds:
To convert from other units of weight to pounds, we need to use the inverse of these conversion factors. For example, to convert kilograms to pounds, we need to multiply by 2.2046226218. Where Pounds are UsedThe pound is a unit of weight that is widely used in the United States and some other countries that have historical ties with Britain, such as Canada and Australia. It is commonly used to measure the weight of people, animals, food, clothes and other everyday items. For example, an average adult male in the United States has a weight of about 198 lbs. The pound is also used to measure some physical quantities such as force, pressure and torque. For example, one poundforce (lbf) is equal to one pound times the standard acceleration due to gravity (32.174 ft/s^{2}). Example Conversions of Pounds to Other UnitsHere are some examples of how to convert pounds to other units of weight using the conversion factors given above:
