Converting Units
@function convert-units()
Convert lengths between comparable units.
You can also convert to browser-ems,
relative to the browser default rather than the site root –
useful for media queries.
Parameters & Return
$length: (length | string)
The length or named size to be converted.
$to-unit: (string)
The desired units to convert to.
Some units (ch, vw, vh, vmin, vmax) cannot be converted.
$from-context: 'root' setting or 16px (length | string)
When converting from relative units,
the absolute length (in px) to which $length refers -
e.g. for $lengths in em units, would normally be the
font-size of the current element.
$to-context: $from-context (length | string)
For converting to relative units,
the absolute length in px to which the output value will refer.
Defaults to the same as $from-context, since it is rarely needed.
@error
Context paremeters must resolve to a value in pixel units.
@error
Failed to convert #{$length} into #{$to-units}.
