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 Catties
The catty (also jin 斤 in Chinese) is a traditional unit of mass used across East and Southeast Asia, equal to 600 grams in its modern metric form. It was historically the standard unit of trade for goods at markets throughout China, Japan, Korea, and Southeast Asia for over a thousand years. Today the catty remains widely used in Chinese, Vietnamese, Malaysian, and Singaporean wet markets and grocery stores for weighing vegetables, meat, and fish. In Hong Kong, the catty (斤) is precisely 604.79 grams; in mainland China it is exactly 500 grams (half a kilogram).
