Fotmal

The fotmal (Old English: fotmael, lit. "foot-measure"; Latin: fotmal), also known as the foot (pes), formel, fontinel, and fotmell, was an English unit of variable weight particularly used in measuring production, sales, and duties of lead.^[1] Under the c. 1300 Assize of Weights and Measures, it was equal to 70 Merchants' pounds and made up 1⁄30 of a load of lead.^[2] Elsewhere, it was made of 70 avoirdupois pounds and made up 1⁄24 load.^[1] According to Kiernan, in 16th-century Derbyshire, the fotmal was divided into "boles" and made up 1⁄30 of a fother, meaning it was considered to be 84 avoirdupois pounds.^[1]

It continued to be used until the 16th century.^[1]
