The fotmal (English, Old (ca.450-1100);: fotmael, "foot-measure"; Latin: fotmal), also known as the foot (Latin: pes), formel, fontinel, and fotmell, was an English unit of variable weight particularly used in measuring production, sales, and duties of lead.Under the Assize of Weights and Measures, it was equal to 70 Merchants' pounds and made up of a load of lead.[1] Elsewhere, it was made of 70 avoirdupois pounds and made up load. According to Kiernan, in 16th-century Derbyshire, the fotmal was divided into "boles" and made up of a fother, meaning it was considered to be 84 avoirdupois pounds.
It continued to be used until the 16th century.
