Collecting and asserting units mentioned above, my proposal is to add 
the following absolute length units to css-values:

- **General metric units:** `m` ‘meter’, `dm` ‘decimeter’ and either 
`mu` for µ ‘micron’ or `um` for µm ‘micrometer’ (but not `mum`). 
Obviously, `1m` = `10dm` = `100cm` = `1000mm` = `1000000um` or 
`1000000mu` ≈ `3780px`.
- **Typographic metric units:** `cc` ‘cicero’, `dd` ‘didot’ with `1cc`
 = `12dd` = `4.5mm` ≈ `17px`. <!-- `1mdl` ‘module’ = `12thm` ‘thumb’ =
 `300mm` = `800dd` -->
- **General English units:** `yd` ‘yard’, `ft` ‘foot’ and `hd` ‘hand’ 
with `1yd` = `3ft` = `9hd` = `36in` = `3456px`.
- **Fractional English units:** `sx` ‘sixteenth-inch’ or ‘six-pixel’, 
`tx` ‘thirtysecondth-inch’ or ‘three-pixel’ and `twip` 
‘twentieth-point’ with `1in` = `16sx` = `32tx` = `96px` = `72pt` = 
`1440twip`.
- **Common anchor unit:** `gcd`, `emu` or, preferably, `dot`. `1q` = 
`360dot`, `1pt` = `508dot`, `1px` = `381dot`.<!-- = `480mp` -->
