  2. Dram (unit) - Wikipedia

    en.wikipedia.org/wiki/Dram_(unit)

    Today's US teaspoon is equivalent to exactly 4.92892159375 ml, which is also 1 ⁄ 6 US fluid ounces, 1 + 1 ⁄ 3 US fluid drams, [5]: C-18 or 80 US minims. [5]: C-5 C-5 While pharmaceuticals are measured nowadays exclusively in metric units, fluid drams are still used to measure the capacity of pill containers .

  3. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Stoichiometry is not only used to balance chemical equations but also used in conversions, i.e., converting from grams to moles using molar mass as the conversion factor, or from grams to milliliters using density. For example, to find the amount of NaCl (sodium chloride) in 2.00 g, one would do the following:

  4. Grain (unit) - Wikipedia

    en.wikipedia.org/wiki/Grain_(unit)

    C-19 [9] One gram is thus approximately equivalent to 15.432 36 grains. [6]: C-13 The unit formerly used by jewellers to measure pearls, diamonds, and other precious stones, called the jeweller's grain or pearl grain, is equal to 1 ⁄ 4 carat (50 mg; 0.77 gr). [5] The grain was also the name of a traditional French unit equal to 53.115 mg. [5]

  5. Mass concentration (chemistry) - Wikipedia

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

    In chemistry, the mass concentration ρ i (or γ i) is defined as the mass of a constituent m i divided by the volume of the mixture V. [1]= For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.

  6. Percent active chlorine - Wikipedia

    en.wikipedia.org/wiki/Percent_active_chlorine

    From the above equations it can be seen that 2 moles of thiosulfate is equivalent to 70.9 grams (2.50 ounces) of active chlorine. Again the percentage of available chlorine can be calculated through the concept of normality. The gram equivalent of bleaching powder is equal to the gram equivalent of the standard titrant used.

  7. Pinch (unit) - Wikipedia

    en.wikipedia.org/wiki/Pinch_(unit)

    1 UK pinch = ⁠ 1 / 16 ⁠ UK tablespoon = ⁠ 1 / 8 ⁠ UK dessert spoon = ⁠ 1 / 4 ⁠ UK teaspoon = ⁠ 1 / 2 ⁠ UK salt spoon: ≈ 0·06: US customary tablespoon: ≈ 0·09: US customary dessert spoon

  8. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    In granulometry, the particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. [1]

  9. Degree Lintner - Wikipedia

    en.wikipedia.org/wiki/Degree_Lintner

    The 0.1 mL of this infusion is equivalent to 0.005 g of malt. Therefore, 5.8 IU/0.005 g of malt = 1160 IU/gram of malt. 100 °L is equivalent to 1160 IU per gram of malt (or 526,176 IU per pound). This value is useful if alternatives to Fehling's reaction are being used to determine the amylase activity.
