  2. Lambda (unit) - Wikipedia

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

    Lambda (written λ, in lowercase) is a non-SI unit of volume equal to 10 −9 m 3, 1 cubic millimetre (mm 3) or 1 microlitre (μL).Introduced by the BIPM in 1880, [1] the lambda has been used in chemistry [2] and in law for measuring volume, but its use is not recommended.

  3. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    m(NaCl) = 2 mol/L × 0.1 L × 58 g/mol = 11.6 g. To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore ...

  4. Mass concentration (chemistry) - Wikipedia

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

    A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). The common names of intravenous sugar solutions, such as D5W and D50W, reflect this convention. The notation is mathematically flawed because the unit "%" can only be used for dimensionless quantities. "Percent ...

    The kayser (K) is a unit of wavenumber equal to 1 cm −1 (100 m −1). The gal (Gal) is a unit of acceleration equal to 1 cm/s 2. [3] The dyne (dyn) is a unit of force equal to 1 g⋅cm⋅s −2 (10 μN). [3] The barye (Ba) is a unit of pressure equal to 1 dyn⋅cm −2 (100 mPa). The erg (erg) is a unit of energy equal to 1 dyn⋅cm (100 nJ ...

  6. Litre - Wikipedia

    en.wikipedia.org/wiki/Litre

    Hence 1 L ≡ 0.001 m 3 ≡ 1000 cm 3; and 1 m 3 (i.e. a cubic metre, which is the SI unit for volume) is exactly 1000 L. From 1901 to 1964, the litre was defined as the volume of one kilogram of pure water at maximum density (+3.98 °C) [ citation needed ] and standard pressure .

  7. List of unusual units of measurement - Wikipedia

    en.wikipedia.org/wiki/List_of_unusual_units_of...

    The US Food and Drug Administration (FDA) defines the "food labeling ounce" as 30 ml (1.1 imp fl oz; 1.0 US fl oz), slightly larger than the 29.6 ml (1.04 imp fl oz; 1.00 US fl oz) fluid ounce. [37] Several Dutch units of measurement have been replaced with informal metric equivalents, including the ons or ounce.

  8. 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.

  9. Cuo (unit) - Wikipedia

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

    A Cuo (Chinese: 撮; pinyin: cuō) in China or sai in Japan is a unit of volume measurement. [1] One cuo equals 1⁄1000 sheng. It is 1 mL (millilitres) in China [2] and 1.804 mL in Japan. [3] The word cuo (撮) means (a) to pick up (e.g., salt) using one's fingertips, or (b) the small amount of something that can be picked up in this way. [1]
