Refers to the gram-molecular weight of a substance in grams.
Each mole (mol) consists of approximately 6 x 10 to the 23rd power molecules.
The millimole (mmol) is 1/1000 of a mole and the micromole is 1/1,000,000 of a mole.
Molecular weight of a substance is the ratio of the mass of one molecule of the substance to the mass of one twelfth the mass of an atom of carbon-12.
The Dalton (Da) is a unit of mass equal to one twelfth the mass of an atom of carbon-12.
1000 Da is equal 1 kilo Dalton.
