Template:Convinfobox/doc

This is a documentation subpage for Template:Convinfobox.
It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 220,000 pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:ConvertIB (sandbox)

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

Paired units

Length may be expressed in feet and inches.

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

Similarly, mass may be expressed in pounds and ounces.

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

Mass may also be expressed in stone and pounds.

{{convinfobox|65|kg||st||lb}} → 65 kg (143 lb; 10 st 3 lb)
{{convinfobox||kg|10|st||lb}} → 10 st 0 lb (64 kg; 140 lb)
{{convinfobox||kg|10|st|7|lb}} → 10 st 7 lb (67 kg; 147 lb)
{{convinfobox||kg||st|145|lb}} → 145 lb (66 kg; 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 ml (13.2 imp fl oz; 12.7 US fl oz)
{{convinfobox|375|ml||impoz|32|USoz}} → 375 ml (13.2 imp fl oz; 12.7 US fl oz)
{{convinfobox||ml|40|impoz|32|USoz}} → 40 imp fl oz (1,100 ml; 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 ml; 38.43 US fl oz)
{{convinfobox||ml|40|impoz||USoz|sigfig=3}} → 40 imp fl oz (1,140 ml; 38.4 US fl oz)
{{convinfobox||kg|10|st|7|lb|3}} → 10 st 7 lb (66.678 kg; 147.000 lb)
{{convinfobox||kg|10|st|7|lb|sigfig=5}} → 10 st 7 lb (66.678 kg; 147.00 lb)

Specify precision "0" to prevent rounding of values ending in zero:

kilograms (kg)
- with "0": {{convinfobox|110|kg||lb|0}} → 110 kg (243 lb)
- without: {{convinfobox|110|kg||lb}} → 110 kg (240 lb)
pounds (lb)
- with "0": {{convinfobox||kg|240|lb|0}} → 240 lb (109 kg)
- without: {{convinfobox||kg|240|lb}} → 240 lb (110 kg)
metres (m)
- with "0": {{convinfobox|100|m||ft|0}} → 100 m (328 ft)
- without: {{convinfobox|100|m||ft}} → 100 m (330 ft)
inches (in)
- with "0": {{convinfobox||cm|100|in|0}} → 100 in (254 cm)
- without: {{convinfobox||cm|100|in}} → 100 in (250 cm)

Leaving all numerical fields blank

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