About Avoirdupois Drams
An avoirdupois dram (dr av) is 1/16 of an avoirdupois ounce - approximately 1.772 grams. Part of the avoirdupois system that governs everyday trade weights in the UK and US, it was historically used to measure small quantities of goods and spices in commerce. While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified in grains and drams), and in archaic recipe books.
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).
