An ounce is larger than a gramme. Each avoirdupois ounce contains roughly 28.35 grammes, while each troy ounce contains around 31.10 grammes. In most nations, the gramme is a standard unit of measurement and is defined as 1/1000 kilogramme.
Typically, avoirdupois ounces are employed. These are components of the prevalent system in the United States. Troy ounces are used to measure precious metals but are rarely utilised outside the commodities industry. Only the United States uses the ounce as an official unit of measurement.
