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 Tolas
A tola is a traditional South Asian unit of mass equal to the weight of a silver rupee coin - approximately 11.664 grams. It was the standard unit for weighing gold and silver across India, Pakistan, Nepal, and Bangladesh for centuries, and remains actively used in gold jewellery markets throughout the subcontinent. Gold is routinely priced and bought in tolas at jewellers' shops (sarrafas) in India and Pakistan. A 10-tola gold bar (116.64 g) is the most popular retail gold bar size in South Asia and the Middle East.
