Шаблон:Convinfobox/doc

This template is a frontend for {{convert}}. It is intended as a meta-template for use within the code for a template, where the input is not known a priori. For unit conversions within articles, one should use {{convert}} directly.

This template accepts from four to seven unnamed parameters. Odd parameters must be numerical (or empty) and specify the numerical value of a measurement and the intended precision of the conversion. Even parameters must be unit codes as used in {{convert}}. Named parameters are the same as used by {{convert}}.

This template differs from {{convert}} in the following respects.

The units to convert to and the units to convert from must be specified (therefore there are no default convert-to units).
Fields for the numerical value of a measurement may be left blank.
The default is to abbreviate units (where abbreviations exist).
Range conversions are not available.

This template may be used when it is unknown in which direction the conversion is to be made. The direction is determined as shown in the following examples.

{{convinfobox|100|m2||sqft}} → 100 m² (1,100 sq ft)
{{convinfobox||m2|100|sqft}} → 100 sq ft (9.3 m²)

Dual conversions

Dual conversions may be performed by adding a fifth (possibly blank) and sixth unnamed parameter.

{{convinfobox|375|ml||impoz||USoz}} → 375 мl (13.2 imp fl oz; 12.7 US fl oz)
{{convinfobox||ml|40|impoz||USoz}} → 40 imp fl oz (1,100 мl; 38 US fl oz)
{{convinfobox||ml||impoz|32|USoz}} → 32 US fl oz (950 мl; 33 imp fl oz)

Paired units

Length may be expressed in feet and inches.

{{convinfobox|180|cm||ft||in}} → 180 см (5 ft 11 in)
{{convinfobox||cm|5|ft||in}} → 5 ft (150 см)
{{convinfobox||cm||ft|120|in}} → 120 in (300 см)
{{convinfobox||cm|5|ft|6|in}} → 5 ft 6 in (168 см)
{{convinfobox||ft||in|180|cm}} → 180 см (5 ft 11 in)
{{convinfobox|5|ft||in||cm}} → 5 ft 0 in (152 см)
{{convinfobox||ft|120|in||cm}} → 120 in (300 см)
{{convinfobox|5|ft|6|in||cm}} → 5 ft 6 in (168 см)

Similarly, mass may be expressed in pounds and ounces.

{{convinfobox|8.5|kg||lb||oz}} → 8.5 кg (18 lb 12 oz)
{{convinfobox||kg|4|lb|3|oz}} → 4 lb 3 oz (1.9 кg)

Mass may also be expressed in stone and pounds.

{{convinfobox|65|kg||st||lb}} → 65 кg (143 lb; 10 st 3 lb)
{{convinfobox||kg|10|st||lb}} → 10 st 0 lb (64 кg; 140 lb)
{{convinfobox||kg|10|st|7|lb}} → 10 st 7 lb (67 кg; 147 lb)
{{convinfobox||kg||st|145|lb}} → 145 lb (66 кg; 10 st 5 lb)

Specifying more than one value

The template currently bases conversions on the first non-blank numerical value ignoring any secondary or tertiary values.

{{convinfobox|100|m2|100|sqft}} → 100 m² (1,100 sq ft)
{{convinfobox|375|ml|40|impoz||USoz}} → 375 мl (13.2 imp fl oz; 12.7 US fl oz)
{{convinfobox|375|ml||impoz|32|USoz}} → 375 мl (13.2 imp fl oz; 12.7 US fl oz)
{{convinfobox||ml|40|impoz|32|USoz}} → 40 imp fl oz (1,100 мl; 38 US fl oz)

Rounding

As with {{convert}} rounding can be done automatically or manually by specifying the precision and/or number of significant figures in the converted value. The number of significant figures can be determined by the parameter |sigfig=. The precision can be determined by the fifth (if there is no sixth) or seventh (if there is a sixth) unnamed parameter as shown in the examples below.

{{convinfobox|100|m2||sqft|4}} → 100 m² (1,076.3910 sq ft)
{{convinfobox|100|m2||sqft|sigfig=4}} → 100 m² (1,076 sq ft)
{{convinfobox||ml|40|impoz||USoz|2}} → 40 imp fl oz (1,136.52 мl; 38.43 US fl oz)
{{convinfobox||ml|40|impoz||USoz|sigfig=3}} → 40 imp fl oz (1,140 мl; 38.4 US fl oz)
{{convinfobox||kg|10|st|7|lb|3}} → 10 st 7 lb (66.678 кg; 147.000 lb)
{{convinfobox||kg|10|st|7|lb|sigfig=5}} → 10 st 7 lb (66.678 кg; 147.00 lb)

Leaving all numerical fields blank

If all numerical value fields are left blank the template returns nothing.
