Calculators

Calculators.

All kinds of handy calculators.  I found the site when I did a search to find a calculator to figure the length of material left on a roll.  The one here seems to be pretty good.  Input the diameter of the roll, the thickness of the material, and the diameter of the center of the roll and it spits out the length.  Seems I have about 26+ feet of insulation left on the roll, which is enough to do about 2/3 of the bathroom area arched roof/wall.  Which with the blueboard and other assorted bits I can finish insulating that area without having to get more materials!  Know what I am gonna be doing tomorrow… 😉
