{{Convert/scale}} allows a custom scale formula to be used to convert a unit into another unit. The formula used is:
- output = round(a × (
{{{1}}}+ offset) + b, r)
- output = round(a × (
That is, output is calculated by adding parameters {{{1}}} and offset, multiplying the result by parameter a, adding parameter b, then rounding according to parameter r.
Usage
ಬದಲಾಯಿಸಿThe format is:
- {{convert/scale|10.0|ww|zz|a=6.7|b=0.4|r=3}} → 10.0 ww (67.400 zz)
- {{convert/scale|4|m|ft|scale=3.28|add=0}} → 4 m (13.1 ft)
Synonyms for parameter a are f or scale. A synonym for parameter b is add.
The output of the template is the following space-separated group of values:
{{{1}}} {{{2}}}(output{{{3}}})
Non-breaking spaces are the default between values and units, but can be reset by using a leading space or " " or "-" prefix before words.
If parameter sep is present, it replaces the opening parenthesis and there is no closing parenthesis.
The parameters are:
| Param | Description |
|---|---|
| 1 | Amount to convert (can have a fraction, default: 2+3/4) |
| 2 | Literal input unit name or symbol (can have prefix "-" or space) |
| 3 | Literal output unit name or symbol (or prefix "-" or space) |
| a or f or scale |
Scale factor (default: 2.0), to divide by 4, use a=(1/4) |
| offset | Initial offset amount (default: 0.0) |
| b or add | Final shift amount (default: 0.0) |
| r | Number of decimal places in the result. Negative numbers round to nearest multiple of powers of 10 (i.e. -3 rounds to the nearest thousand). i.e., rounding is to the nearest multiple of 10−r. The default value of r is the precision of parameter 1, plus 1.
|
| sep | Separator text between input unit & output amount (default: "( )" parentheses) |
