About Short Hundredweights
A short hundredweight (cwt, US cwt) equals exactly 100 pounds or approximately 45.359 kg. Used primarily in the United States for commodity trading, it represents the practical 'hundred-pound' unit for measuring coal, agricultural produce, livestock feed, and industrial materials. Commodity markets for cattle, hogs, and grain in the US price their products per hundredweight ($/cwt or $/100 lb). Steel and non-ferrous metal quotations in North America are commonly expressed in dollars per short hundredweight. The 'short' modifier distinguishes it from the UK long hundredweight (112 lb).
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.
