Formula's include:

-Basic Stair Calculations
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
Enter the shortest span of a house and the roofs pitch. Option to 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
Cylinder volumes or Square/Rectangle volumes:
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.

OHM's Law: Input any two of the Power/Watts, Resistance/OHM's, Current/AMPS, or Voltage to result in the other two required information. Quick and Simple!

Board Feet & Cost calculator
Input Length, Nominal Width, and Nominal thickness to determine how much board feet you have or need. Also input the quantity you need and price per BF to figure out the total costs or required material!

Wall Finishes:
-Siding calculator & Cost Estimating
-Brick / Block calculator & Cost Estimating
-Drywall calculator & Cost Estimating
-Paint calculator & Cost Estimating
-Framing wall stud calculator & Cost Estimating

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.

3-4-5 button:
input any two lengths from your corner your trying to square 90 degrees. The output will be in fractions and decimals for both metric and imperial users. you can even combine one with the other in the input. Enter a decimal number in the X or Y axis slot, and in the other axis you can mix it with a fraction and still get both results in decimal and fractions. This is advanced feature not offered in the free version.

Fractions button:
This is an entirely new calculator as a sub menu. This is strictly for adding, subtracting, multiplying or dividing fractions and whole numbers. There is a show/hide decimal button to convert your answer into decimal.
inputting a decimal to return the fraction will be added in a future update.
