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.
In fractions like "2 nanometers per meter" (2 n m / m = 2 nano = 2×10 −9 = 2 ppb = 2 × 0.000 000 001), so the quotients are pure-number coefficients with positive values less than or equal to 1. When parts-per notations, including the percent symbol (%), are used in regular prose (as opposed to mathematical expressions), they are still pure ...
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 .
exactly equal ≈ approximately equal to ≘ (exactly) corresponds to (different types of quantity describing the same phenomenon) digits: indicates that digits repeat infinitely (e.g. 8.294 369 corresponds to 8.294 369 369 369 369...) (H) of chiefly historical interest
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.
14 micrograms of vitamin D (71% of daily value) 8.6 milligrams of niacin (54% of daily value) Wild salmon is a great source of protein that's packed with healthy fats, vitamins and minerals.
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 ...
