By subtracting tare weight from gross weight (laden weight), one can determine the weight of the goods carried or contained (the net weight).
Etymology
The word tare originates from the Middle French word {{lang|frm|tare}} 'wastage in goods, deficiency, imperfection' (15th {{abbr|c.|century}}), from Italian {{lang|it|tara}}, from Arabic {{lang|ar|طرح}} {{Transliteration|ar|ṭarḥ}}, lit. 'thing deducted or rejected', from {{Transliteration|ar|taraha}} 'to reject'.{{cite web |url=http://www.etymonline.com/index.php?term=tare |title=tare (2) |work=Online Etymology Dictionary}}
Usage
Tare weight 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 displayed upon the sides of railway cars and transport vehicles to facilitate the computation of the load carried. It is also used in body composition assessment when doing underwater weighing.[https://us.humankinetics.com/blogs/excerpt/provide-an-estimate-of-total-body-volume-with-hydrostatic-weighing Underwater weighing]
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 added into the container.
