Template:Convinfobox

Documentation icon Template documentation[view] [edit] [history] [purge]

This template is based on {{convert}}. It is intended as a meta-template for use in infoboxes. It 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}} gives "Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value)."
  • {{convinfobox||m2|100|sqft}} gives "Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value)."

Leaving all numerical fields blank

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

  • {{convinfobox||m2||sqft}} gives ""
  • {{convinfobox||ml||impoz||USoz}} gives ""

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}} gives "Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value)."

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}} gives "Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value)."
  • {{convinfobox|100|m2||sqft|sigfig=4}} gives "Lua error in Module:Convert at line 1850: attempt to index local 'en_value' (a nil value)."
