Enter the thickness of the plank and any other two of your required measurements to compute for the other measurements of the angled plank. Please leave blank the values to be calculated. Side "E" is the inner length of the plank and side "F" is the outer longer length of the plank. There may be more than one solution to a given set of inputs. Please take note that thickness of the plank is in inches. The initial units used in the table can be changed to any of the choices given. The number of decimal places in the calculated values can be specified.

Please take note that the length unit - millimeter (mm) has recently been added to the units choices.
