For example, in the 1930s Widmark measured alcohol and blood by mass, and thus reported his concentrations in units of g/kg or mg/g, weight alcohol per weight blood. Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g.
DRIs are established for elements, vitamins, and macronutrients. Common elemental [17] and vitamin [18] doses are measured in milligrams per day (mg/d) or micrograms per day (μg/d). Common macronutrient [19] doses are in grams per day (g/d). Recommended doses for all three are established by both gender and age.
