模板:Infobox settlement/pref

This is a subtemplate of {{Infobox settlement}}. It is not intended to be used directly. It is called by the following templates:

仅显示公制单位：

{{Infobox settlement/metric_only}}
{{Infobox settlement/metric_only/mag}}

Its purpose is to determine whether those templates call one of the subtemplates that displays metric units first (the default):

{{Infobox settlement/metric}}
{{Infobox settlement/metric/mag}}

or one of the subtemplates that displays imperial units (U.S. units) first:

{{Infobox settlement/impus}}
{{Infobox settlement/impus/mag}}

or the following subtemplates if an area is specified in dunams:

{{Infobox settlement/dunam}}
{{Infobox settlement/dunam/mag}}

Usage

The template handles up to three unnamed parameters.

Text which specifies preference to display either metric or Imperial units first. It is specified as unit_pref in {{Infobox settlement}}, then passed as pref to one of three display subtemplates (/areadisp, /densdisp, /lengthdisp).
Country name, used to determine preferene when not given in first parameter. It is specified as subdivision_name in {{Infobox settlement}}, then passed as name to one of three display subtemplates.
The third parameter is only specified by the /areadisp subtemplate, which passes the text area.

The default is to display metric units first, so the template only checks these parameters for values that would indicate the need to display non-metric units first:

Imperial, English, UK, US, U.S., US Customary, U.S. Customary, Standard
United Kingdom, [[United Kingdom]], United States, [[United States]], United States of America, [[United States of America]], [[United States|United States of America]]
if this template is called by the /areadisp subtemplate, then it also checks parameter #1 for dunam (after converting it to lowercase)

`{{Infobox settlement/pref\|Dunam\|Other\|area}}`	dunam
`{{Infobox settlement/pref\|Dunam\|Other}}`	metric
`{{Infobox settlement/pref\|Dunam\|United Kingdom\|area}}` In this example, the template never checks for "Dunam" because it previously found that parameter #2 contained the name of a country using imperial units.	dunam
