Tare weight

From Wikipedia, the free encyclopedia

It has been suggested that Tare and Tret be merged into this article or section. (Discuss)

Tare (pronounced /tɛər/) weight, sometimes called unladen weight, is the weight of an empty vehicle or container. By subtracting it from the gross weight (laden weight), the weight of the goods carried (the net weight) may be determined. This can be useful in computing the cost of the goods carried for purposes of taxation (sometimes called a tariff) or for tolls related to barge, rail, road, or other traffic, especially where the toll will vary with the value of the goods carried (eg tolls on the Erie Canal). Tare weight is often published upon the sides of railway cars to facilitate the computation of the load carried.

[edit] Etymology

From Middle English, perhaps derived from the Dutch tarwe (wheat)^{[citation needed]} or alternatively, French tarhah (that which is thrown away)^{[citation needed]}.
