Mg is an international unit of mass, abbreviated as "mg" in English. It is usually used to measure the composition of liquids and drugs, and mEq in milliequivalents represents the chemical activity or binding force of substances equivalent to 1mg hydrogen.
G and mg are both units of mass. G needs to be multiplied by the coefficient 1000 when converted into mg, and 0.00 1 when converted into g. Quality is the physical property of an object and a measure of the quantity of matter. It is a positive scalar.
Mass is divided into inertial mass and gravitational mass, and any substance in nature has both inertial mass and gravitational mass. The "matter" mentioned here is the general name of macro objects and electromagnetic fields, celestial bodies and galaxies, and basic particles in the micro world in nature. In the international system of units, the basic unit of mass is the kilogram.
Brief comments on gram and milligram
Gram and mg are not ancient units of weight in China, and one gram is equal to 1000 mg. The conversion between these weight units is in thousands. 1 kg equals 1 000g, one gram equals1000mg, and1mg equals1000mg. This is a conversion unit, often seen in mathematics.
The difference between milligrams and grams is 1000, so one gram is equal to 1000 milligrams. No matter how much you weigh, the unit conversion is the same. If you weigh a drug, you must see it. Many people use different names, so they use different units.
