  2. Penicillin - Wikipedia

    en.wikipedia.org/wiki/Penicillin

    Therefore, 2 million units (2 megaunits) of penicillin G is 1.2 g. [22] One unit of penicillin V potassium is defined as 0.625 micrograms. Therefore 400,000 units of penicillin V is 250 mg. [23] The use of units to prescribe penicillin is a historical accident and is largely obsolete outside of the US.

  3. International unit - Wikipedia

    en.wikipedia.org/wiki/International_unit

    In pharmacology, the international unit (IU) is a unit of measurement for the effect or biological activity of a substance, for the purpose of easier comparison across similar forms of substances. International units are used to quantify vitamins and biologics ( hormones , some medications , vaccines , blood products and similar biologically ...

  4. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    Although there are examples to the contrary, it should be stressed that the commonly used "units" of % w/v are grams per millilitre (g/mL). 1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and ...

    mistaken for U, meaning units; also has an ambiguous meaning; use "mL" or "millilitres" (1 cm 3 = 1 mL) cf. confer compare c.n. cras nocte: tomorrow night cochl. cochleare: spoonful cochl. ampl. cochleare amplum: an ample spoonful (a tablespoonful) cochl. infant. cochleare infantis: a small spoonful (a teaspoonful) cochl. mag. cochleare magnum

  6. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...

  7. Pen-Strep - Wikipedia

    en.wikipedia.org/wiki/Pen-Strep

    The solution contains 5,000 units of penicillin G (sodium salt) which acts as the active base, and 5,000 micrograms of streptomycin (sulfate) (base per milliliter), formulated in 0.85% saline. In general, 50-100 units of Pen-Strep per milliliter of media is used to avoid contamination in cell culture.

  8. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  9. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
