The Formula's button will take you to another screen with a sub menu.

-Basic Stair Calculations
in this section you only need to enter the Total Rise of a stair case, and the ideal Tread Run (length)
The calculator will calculate the rest for you and give you a list of desired information and results.

-Basic Roof Calculations
In this section you only need to enter the shortest span of a house and the roofs pitch. Also you can change the default 1 foot overhang. Hitting update will result in:
-common rafter length
-common rafter birdsmouth
-hip/valley length
-hip/valley birdsmouth
-1st jack rafter
-Total Rise
-Total Run
**Details about how to calculate common rafters can be seen if selected

-Basic Concrete Calculations
This section is broken into two sub categories:
Cylinder calculations or Square/Rectangle calculations
You input the length width and height for rectangles in feet and hit update for a result in both cubic metres and cubic yards. Altering the numbers then hitting update again without hitting clear first will add the new total to the current total. This is for rapid adding of area to determine concrete volumes.
In the event you do not know the value in feet, there is tiny mm and inches buttons beside each input boxes. You can input 1 value in mm and hit the mm button to instantly convert it to feet for you, while placing another value in inches and hitting the inch button to convert to total feet in decimal format.
This program will allow the entry of feet, inch, and mm and convert it all to be feet in decimal format to solve the equations into both cubic metres and cubic yards.

Bubble Level
-This is both a bubble level and bullseye level for quick and handy checking of a project to see if it is plumb or level.
