ConCalc is a feet, inch, mm, and fraction calculator with a much improved triangle solver also included.
The objective of ConCalc is to provide a Foot-inch calculator that would be intuitive, easy to use, and fast. Since most professionals who deal with fractions, also regularly solve triangle problems, ConCalc also solves all types of triangle problems (right triangles, acute, obtuse, etc). Just provide three known values, and the calculator will produce the other three un-supplied values.
