It is also possible to use other units. 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. 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.
Dram (unit) The dram (alternative British spelling drachm; apothecary symbol ʒ or ℨ; [ a] abbreviated dr) [ 4][ 5]: C-6–C-7 [ 6] is a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system. [ 5] It was originally both a coin and a weight in ancient Greece. [ 7]
Enzyme unit. The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme 's catalytic activity. [ 1] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method. [ 2]
Blood urea nitrogen ( BUN) is a medical test that measures the amount of urea nitrogen found in blood. The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood should contain 7 to 18 mg/dL (0.388 to 1 mmol/L) of urea nitrogen. [ 1] Individual laboratories may have different reference ...
Standard cubic centimeters per minute ( SCCM) is a unit used to quantify the flow rate of a fluid. 1 SCCM is identical to 1 cm³ STP /min. Another expression of it would be Nml/min. These standard conditions vary according to different regulatory bodies.
Each contains about 14 grams or 17.7 ml of ethanol. A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol. The notion is used in relation to recommendations about alcohol consumption and its relative risks to health. It helps to educate alcohol users. [ 1]
The tonne (t) is an SI-compatible unit of mass equal to a megagram ( Mg ), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
In the United States, Germany, Japan and many other countries mass concentration is measured in mg/dl (milligrams per decilitre). [4] Since the molecular mass of glucose C 6 H 12 O 6 is approximately 180 g/mol, the difference between the two units is a factor of about 18, so 1 mmol/L of glucose is equivalent to 18 mg/dL.
