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.
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 ...

For example, the conversion factor between a mass fraction of 1 ppb and a mole fraction of 1 ppb is about 4.7 for the greenhouse gas CFC-11 in air (Molar mass of CFC-11 / Mean molar mass of air = 137.368 / 28.97 = 4.74). For volume fraction, the suffix "V" or "v" is sometimes appended to the parts-per notation (e.g. ppmV, ppbv, pptv).
This should hold the transit system over until July 1, at which point he expects the legislature to have come up with a longer-term solution. Even with additional funding, Shapiro orders short ...
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.
