Translating or extruding in inches How can I translate or extrude something in inches? If I hit E or G then type a value, it's taken as feet, and if I try to type in ", it's simply ignored.  

I live in metric land, but I do understand imperial units quite well. I usually don't bother setting Blender to anything but the default BU; I simply take 1 BU as 1 m.  

Now I'm trying to model something whose measurements are defined in feet and inches (a pool table with several randomly placed balls). I see several workarounds to the above problem.  

Model in BU and scale down properly once I'm done.
Take 1 BU = 1".
Convert the measurements (or use the converted measurements from the WPA site), and model by the conversions.  

However, I want to model it directly in feet and inches. If nothing else, I might learn something new: working with imperial units in Blender.
A bit of googling lead me to Metric &amp; Imperial Units in Blender.  

@DemonFate's answer, made me try manually setting the scale to 0.0254, which is 1 inch expressed in metres. I assumed the scale was a conversion from BU to whatever unit I wanted. But from the link above, I realised that when Blender is set to Imperial, the scale is a conversion from feet to whatever unit I want. Hence setting it to 0.08333 does the trick. To get the best precision, type in 1/12 and hit Enter, and Blender is smart enough to calculate it.  

  

There are drawbacks, but I can live with them. The Scale and Location values in the Object tab and in the Properties panel now increments in thou, and all values typed in manually when grabbing or extruding are now taken as inches.
