The ounce originated from the Roman 'uncia,' a twelfth part of the Roman pound. The avoirdupois ounce was standardized in the 19th century by the international yard and pound agreement of 1959 to unify US and British definitions [nist-sp-811]. Ounces are widely used in the US for weight measurement in grocery, postal, and manufacturing sectors. The UK uses ounces in certain contexts like precious metals and food portions.

Grains are used primarily in the United States and the UK for measuring bullet and arrow weights, as well as in medicine for doses. The unit is acknowledged in international standards but is largely limited to specific industries [nist-si-guide].
