Use to store, recall & edit length, width, height, area, rise, run, pitch, diagonal, & circle diameter values when calculating or estimating a project.
When selected, a list of currently memorized values pops-up, along with their corresponding labels.

Values & Labels are entered into the Memory bank by pressing the (Mem) button on the main Calculator view. Once pressed, it will ask you to assign the displayed value a label, and will then store it in the memory bank for your reference.
Labels can be modified & items can be deleted by pressing the (Edit) button located at the right corner of the header

If a stored value is selected, it will be added to the display. If a stored value is selected after an equating button has been selected, the desired function will be calculated between the preceding value and the selected stored value once the (=) button is pressed.

If we want to multiply a length of 6' by an existing stored value of 12'-3", we would use the following method:

Use to find the converted values of a variety of units.

When a value is on the display and the (Conv) button is pressed, a list of available unit conversions will be displayed. You can select one of the values to have it replace the currently displayed value on the calculator page. If a value is selected after an equating button has been selected, the desired function will be calculated between the preceding value and the selected stored value once the (=) button is pressed.

By default, if a number is entered on the calculator page without following it with a unit type, it will not be converted into any type of unit.

Use the unit buttons (Yard, Feet, Inch, Inch Fractions / Meter, Centimeter, Millimeter) in collaboration with other equating functions to calculate English & Metric units (depending on which type of units are active) in various ways.
Tap any of the unit buttons once after a number to enter the unit length value. Tap a second time to change to decimal value.

Additionally, once a unit button is pressed, and no other numerical values have been entered, you may hit a different unit button for a quick conversion.

To add 4'-2" & 6'-3-1/8", we would use the following method:

While Linear units are the default input method, Square & Cubic units can be entered by using the SQ/CU/LN toggle button on the bottom left corner of the calculator. You can cycle through the three unit types by using the same button repeatedly.

The button functions as follows:
(SQ): Changes the displayed value from Linear to Square.

(CU): Changes the displayed value from Square to Cubic.

(LN): Changes the displayed value from Cubic to Linear.

To enter a known value of 500 cu. ft., we would use the following method:

Use to calculate properties of a right angle (I.E.: Rafter, Stair Stringer, Rake Wall, etc.).
When a value is entered, it is stored until replaced or the clear button is hit twice. If values are entered, and then a "Quick-Job" is started, the entered values will be included on the job.

The individual functions act as follows:
(Run): Use to enter the known horizontal run of a right triangle.

(Rise): Use to enter the known vertical rise of a right triangle.

(Pitch): Use to enter the known slope of a right triangle. Values can be entered in the following ways:

To manually find the Diagonal & Run values of a right angle, assuming we know that there is a 12' rise & 6/12 pitch, we would use the following method:

Use to calculate dimensional properties (I.E.: Floor Area, Perimeter, & Wall Area, etc.). When a value is entered, it is stored until replaced or the clear button is hit twice.
If values are entered, and then a "Quick-Job" is started, the entered values will be included on the job.

The individual functions act as follows:
(Length): Use to enter the length of an object.

(Width): Use to enter the width of an object.

(Height): Use to enter the height of an object.

To manually find the Perimeter of a building 20'-0" X 34'-8", we would use the following method:

Use to calculate properties of a circle or column. Tap once to enter diameter of a circle. Tap a second time to show the circle area.
To find more circle properties, you can use the "Conv" Button (to find out more about the Conversion function, see "Convert" section of this guide).

To manually find the volume of a column that is 9' tall with an 18" diameter, we would use the following method:

Note: Rafter lengths are from CENTER of ridge to vertical line of seat cut on outside wall and does not account for ridge board width. Rafter tail length is from vertical line of seat cut on outside wall to outside of overhang length and does not account for fascia board.

Note: Results do not include overages required in estimating for blocking, waste, or damaged material.

Note: Stair data does not account for nosing or overhang, nor does it account for dividends in Tread depth & riser height calculations.
Verify minimum code requirements with all apllicable national & local building codes before construction.

Note: Results do not include overages required in estimating for blocking, waste, or damaged material.
