Tower pound
unit of weight
Quick Summary
The Tower pound was a historical unit of weight used in England before 1527, primarily for precious metals and drugs. It was called the "Tower pound" because its standard weight was kept in the Tower of London. This unit contained 5,400 grains, equivalent to approximately 0.350 kilograms or 349.91 grams. The Tower pound was eventually superseded by the troy pound in 1527 as the standard for gold and silver. The British monetary pound, or pound sterling, has historical ties to the minting of silver coins using the Tower pound.12
