    en.wikipedia.org/wiki/Microgram

    In the metric system, a microgram or microgramme is a unit of mass equal to one millionth (1 × 10 −6) of a gram. The unit symbol is μg according to the International System of Units (SI); the recommended symbol in the United States and United Kingdom when communicating medical information is mcg .

    A nanosecond (ns) is a unit of time in the International System of Units (SI) equal to one billionth of a second, that is, ⁠ 1 / 1 000 000 000 ⁠ of a second, or 10 −9 seconds. The term combines the SI prefix nano-indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre, etc.) and second, the primary unit of time in the SI.

  6. Micro- - Wikipedia

    en.wikipedia.org/wiki/Micro-

    The two alternatives are to abbreviate as "mcg" [14] [3] or to write out "microgram" in full (see also List of abbreviations used in medical prescriptions). The alternative abbreviation may be ambiguous in rare circumstances in that mcg could also be read as a micrigram , i.e. 10 −14 g; however the prefix micri is not standard, nor widely ...

  9. Transformation efficiency - Wikipedia

    en.wikipedia.org/wiki/Transformation_efficiency

    For example, if you plate 1x 10 7 cells and count 1000 colonies, the transformation efficiency is: (1000/1x 10 7) x 100 = 0.1% Alternatively, CFUs can be reported per microgram of DNA used for the transformation. This can be calculated by multiplying the number of colonies by the volume of the culture plated and dividing by the amount of DNA used.
