Did you know?
Tare came to English by way of Middle French from the Old Italian term tara, which is itself from the Arabic word ṭarḥa, meaning "that which is removed." One of the first known written records of the word tare in English is found in the naval inventories of Britain's King Henry VII. The record shows two barrels of gunpowder weighing, "besides the tare," 500 pounds. When used of vehicles, tare weight refers to a vehicle's weight exclusive of any load. The term tare is closely tied to netweight, which is defined as "weight excluding all tare."
