(1/2, 1/8, 1/16) or improper (3/2, 9/8). If the denominator (bottom) is not entered, the calculator's fractional resolution setting is auto- matically used (e.g., entering 1 5 / = or + will display 15/16, based on the default fractional resolu- tion setting of 16ths.
Meters — Enters or converts to Meters . Ç 7 Centimeters (cm) — Enters or converts to Centimeters . Ç 9 Millimeters (mm) — Enters or converts to Millimeters . Ç 2 Acres (Acre) — Enters or converts (a square value) to Acres .

Construction Project Keys and Functions The following Construction Project Keys and Functions help you instantly figure quantities and costs of materials, so you can build like a pro! Block/Brick Function ( The Blocks function helps you quickly estimate the quantity of blocks or bricks required for building walls, walkways or other areas.
(based on the stored On-center spacing), listed below. Press Result * The calculator will calculate arched segment wall lengths (if applicable) with consecutive presses of the a key until it reach- es the last wall length.
* Wall Corner Angle entries of less than 25 into  will be assumed to be the number of sides of a polygon; in this case, the calculator will calculate the unknown Wall Corner Angle first, then proceed with the above angle calculations.
Drywall Function ( NOT AVAILABLE ON TRIG MODEL Ç h Drywall Sheets (Drywall) — Calculates the number of 4 x 8, 4 x 9, and 4 x 12 sheets for an entered or calculated area. Footing Function ( NOT AVAILABLE ON TRIG MODEL The Footing function helps you quickly estimate the volume of concrete required for concrete footings.
Pitch Ratio/Slope). Note: An entered (vs. calculated) pitch is a permanent entry. This means that it will remain stored even after you turn the calculator off. To change the Pitch, simply enter a new Pitch value. In contrast, a calculated Pitch value is not permanently stored.
Ç p Pitch Ratio or Slope (Slope) — Enters the Pitch as a ratio or Slope of a roof (or right triangle). For example, 0.58 slope is entered as • 5 8 Ç Rise — Enters or calculates the Rise or vertical leg (height) of a right triangle.
Page 20
When calculating Regular and Irregular Jack rafter lengths, you will see the letters “JK” (Regular pitch side) or “IJ” (Irregular pitch side) and the corresponding jack number to the left of your calculator dis- play. This will help you keep track of the descending sizes and which side the corresponding rafter is based on.
(see Preference Settings on page 83). Note: You may set your calculator to “mate up” with the Jack Rafters, rather than using the entered or default On-center spacing for both sides (see Preference Settings on page 83).
Roof Materials/Covering Function The Construction Master Pro's Roof function provides a quick calcu- lation of roof area, number of squares and bundles, and number of 4 x 8 sheets required for roof coverage. Ç d Roof — Given an entered Pitch (or Rise and Run) and plan area (or Length and Width), calculates the following: Press Result...

Riser Height of 7-1/2 Inches, if 7-1/2 Inches is the value stored using ß 7). To compensate for this limitation, the calculator will add one to the number of risers. Studs Function The Construction Master Pro also calculates the number of studs required for a wall using an entered length and stored On-center spacing value.
