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 ...
1 ⁄ 100 of the energy required to warm one gram of air-free water from 0 °C to 100 °C at a pressure of 1 atm ≈ 4.190 02 J: ... ice IT = 144 °F × 2326 J/kg⋅°F
The provisional tolerable daily intake (PTDI) for patulin was set at 0.43 μg/kg body weight by the FDA [3] based on a NOAEL of 0.3 mg/kg body weight per week. [3] Monte Carlo analysis was done on apple juice to compare exposure and the PTDI. Without controls or an action limit, the 90th percentile of consumers would not be above the PTDI.
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 .

Software by NIST for compression of structure with mass spectra. The program seeks to find mechanisms and their rates for all fragmentation types (EI, Tandem positive and negative mode) and correlates mass spectral peaks to a probable origin structure. It contains an isotope calculator and other features and on-line help.
