_unitconversion.scss (v.2.2.0)

Convert Anything (almost)

At the moment the following units are supported (please comment if something is wrong/missing):

px, pt, pc, in, mm, cm, em, rem, ex, ch, vw, vh, vmin, vmax, 
deg, rad, grad, turn, dpi, dpcm, dppx, s, ms, hz, khz, number,
ratio 

NPM

npm install unitconversion

Simple Syntax

Rather than going with the "good" old fromUnit-to-toUnit(fromUnit) syntax this function set is based on toUnit(fromUnit) making it a lot shorter and less cumbersome to maintain – as shown below :-)

       pt-to-px(input);
       pc-to-px(input);       
       in-to-px(input);       
       mm-to-px(input);    ==>   px(input);   
       cm-to-px(input);              
       em-to-px(input);              
       rem-to-px(input);                     
       num-to-px(input);  

Note!

• To allow conversion between relative and absolute lengths em and rem are calculated as pixel values based on $root-font-size and $base-font-size (16px browser default). If you change the base font size of your document – remember to set the $root-font-size and $base-font-size variables accordingly.

• To ease the job of handling compounds the em function takes multiple arguments. Each argument is treated as an em compound and used to calculate the visual size. Example – how to set a visual size of 18px on a class nested in an element with a font-size of 2em:

      .class {
          font-size: em(18px, 2em);  ==>   0.5625em;
      }

• If you use unit conversion in relation to the font shorthand syntax be aware that line-height "/" will cause division. To prevent this from happening you can either either interpolate the value or use + to add the pieces together without calculation:

      h2 { 
          font:300 #{em(24px)}/3 'Lato', sans-serif;
      }
