  2. 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 ...

  3. 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 ...

    Here, the base units are the quad, equal to 10 7 m (approximately a quadrant of the Earth's circumference), the eleventhgram, equal to 10 −11 g, and the second. These were chosen so that the corresponding electrical units of potential difference, current and resistance had a convenient magnitude.

  6. Metric prefix - Wikipedia

    The financial and general news media mostly use m or M, b or B, and t or T as abbreviations for million, billion (10 9) and trillion (10 12), respectively, for large quantities, typically currency [28] and population. [29] The medical and automotive fields in the United States use the abbreviations cc or ccm for cubic centimetres.
