Feet and inches calculator

I wrote this little tool a few years ago and it came in quite handy doing some basic measurements in feet, inches, and fractiontional inches. Just enter some lengths in the format IN, FT', or FT'IN" and add (+), subtract (-), multiply (*), or divide (/). Note that measurements without a unit are assumed to be inches.

Some examples:

  • To get the total length of (3) lengths of 2’-3 5/64”, enter (2'3+5/64)*3, which is 6'-9 0.234375"
  • To divide a length of 21’-7 1/8” into 3 parts, enter (21'7+1/8)/3, which is 7'-2 1/2"

 

Result:
