About Nanograms
A nanogram (ng) is one billionth of a gram (10⁻⁹ g). This is the standard mass unit in analytical chemistry, pharmacology, and toxicology for detecting trace substances. Blood plasma concentrations of hormones, drugs, and environmental contaminants are routinely reported in nanograms per milliliter (ng/mL). A typical therapeutic blood level for many medications is in the range of 10-500 ng/mL. In forensic science, nanogram-level DNA quantities can be amplified by PCR to yield a full genetic profile.
About Pounds
The avoirdupois pound (lb) is the primary unit of weight in the United States and United Kingdom for everyday use, equal to 16 ounces or exactly 453.59237 grams. It dominates American life: body weight, grocery produce, deli counter cuts, freight shipping costs, gym weights, and building material quantities are all measured in pounds and ounces. American recipes use pounds for meat and large quantities. The pound derives from the Roman 'libra pondo' (a pound by weight) - hence both the symbol 'lb' (from libra) and the British currency symbol '£'.
