In package grid you can use several different units.

In base graphics there are a very few par()s that use inches (and I am 
pretty sure that comes from the US unit as used in S, not the 'Imperial' 
one -- see e.g. Wikipedia).  But those are rarely used.

Also most graphics devices are dimensioned in inches with resolutions in 
dpi.

Function cm() might help you.
