Editing Quintal (section)

== Name ==
The concept has resulted in two different series of masses: Those based on the local pound (which after [[metrication]] was considered equivalent to {{convert|0.5|kg|abbr=on}}, and those uprated to being based on the kilogram.

In Albania ({{lang|sq|kuintal}}), Ethiopia ({{lang|am-Latn|kuntal}}), and [[India]], the {{convert|100|kg|lb|0|abbr=on}} definition may have been introduced via Islamic{{Citation needed|reason=and why not occidental influence|date=June 2019}} trade.  It is a standard measurement of mass for agricultural products in those countries.

In France it used to be defined as 100 {{lang|fr|livres}} (pounds), about {{convert|48.95|kg|lb|0|abbr=on}}, and has been redefined as 100&nbsp;kg ({{lang|fr|[[mesures usuelles]]}}), thus called ''metric quintal'' with symbol ''qq''. In [[Spain]], the {{lang|es|quintal}} is still defined as 100 {{lang|es|libras}}, or about {{convert|46|kg|lb|0|abbr=on}}, but the ''metric quintal'' is also defined as 100&nbsp;kg;<ref>[[Real Academia Española]]'s [http://lema.rae.es/drae/?val=quintal definition of ''quintal'']</ref> In Portugal a quintal is 128 {{lang|pt|[[arrátel|arráteis]]}} or about {{convert|58.75|kg|lb|0|abbr=on}}.<!-- source? -->

The German {{lang|de|[[:de:Zentner|Zentner]]}} and the Danish {{lang|da|[[:da:Centner|centner]]}} are pound-based, and thus since metrication are defined as {{convert|50|kg|lb|0|abbr=on}}, whereas the Austrian and Swiss {{lang|de|Zentner}} since metrication has been re-defined as 100&nbsp;kg. In Germany a measure of 100&nbsp;kg is named a {{lang|de|Doppelzentner}}.

In Italy, the {{lang|it|[[:it:Quintale|quintale]]}} is commonly used to refer to 100&nbsp;kg and is abbreviated to ''q'', but the usage is considered informal and is not considered legally valid since 1990.<ref>https://www.sapere.it/enciclopedia/quintale.html</ref>

Common agricultural units used in the [[Soviet Union]] were the 100&nbsp;kg {{lang|ru-Latn|tsentner}} ({{lang|ru|центнер}}) and the term "{{lang|ru-Latn|tsentner}} per [[hectare]]". These are still used by countries that were part of the Soviet Union.
