Tare weight /ˈtɛər/, sometimes called unladen weight, is the weight of an empty vehicle or container.[1] By subtracting tare weight from gross weight (laden weight), one can determine the weight of the goods carried or contained (the net weight).

Tare weight: 2,230 kg (4,920 lb)

EtymologyEdit

The word tare originates from the Middle French word tare “wastage in goods, deficiency, imperfection” (15th c.), from Italian tara, from Arabic طرح ṭarḥ, lit. “thing deducted or rejected”, from taraha “to reject”.[2]

UsageEdit

 
With a laboratory scale, the tare weight is the mass of the flask and the net weight is the mass of the contents.

This can be useful in computing the cost of the goods carried for purposes of taxation or for tolls related to barge, rail, road, or other traffic, especially where the toll will vary with the value of the goods carried (e.g., tolls on the Erie Canal). Tare weight is often published upon the sides of railway cars and transport vehicles to facilitate the computation of the load carried. Tare weight is also used in body composition assessment when doing underwater weighing.[citation needed]

Tare weight is accounted for in kitchen scales, analytical (scientific) and other weighing scales which include a button that resets the display of the scales to zero when an empty container is placed on the weighing platform, in order subsequently to display only the weight of the contents of the container.

net weight (weight of the goods) = gross weight (total weight) - tare weight (weight of the empty container)
