The ProjectCalc Plus was designed specifically for Do-it-
Yourselfers. It helps you quickly figure project material
quantities, linear distances, areas/volumes and material costs
like a pro. Unlike other calculators, it works and converts
directly in Feet-Inches-Fractions, Yards, Metric, Square and
Cubic, so you don’t have to figure tedious math.
Use it to estimate quantities & costs for:
• Board Feet/Lumber • Bricks/Blocks
• Carpet • Concrete
• Deck • Drywall
• Fence • Gravel
• Mulch • Paint
• Roofing Bundles • Studs
• Tile • Wallpaper
The ProjectCalc Plus is an indispensable tool for all your
home Do-It-Yourself projects!
KEY DEFINITIONS

Arithmetic operation keys.
[0] — [9] and [ • ]
Digits used for keying in numbers.
[ / ] — Fraction Bar
Convert Key Functions
[Conv] — Convert Key
Used with the dimensional unit keys to convert between
dimensions, the Project Keys to compute material quanti-
ties, or with other keys to access special functions.
[Conv] [ x ] — Clear All
Clears all stored values and sets calculator back to defaults.
[Conv] [ – ] — Sign ( + / –)

[Conv] [ / ] ( %) — Percent
Memory
[Stor] [Met] ( M+) — Adds or stores a value in the semi-
permanent memory (e.g., 150 [Stor] [Met]). Semi-perma-
nent means the value is cleared when the calculator is
turned off.
[Conv] [–] [Stor] [Met] ( M-) — Subtracts a value from
the semi-permanent memory (e.g., 150 [Conv] [–] [Stor]
[Met] subtracts 150 from the memory).
[Rcl] [Met] ( M-R/C) — Recalls memory value (e.g., if
150 has been stored in Memory, pressing [Rcl] [Met] will
display 150).
[Rcl] [Rcl] ( MC) — Displays and clears memory value.
[Conv] [On/C] ( Off) — Clears memory value.
Dimensional Unit Keys
[Yds] — Yards Key
Enters or converts to yards.
[Feet] — Feet Key
Enters or converts to feet as whole or decimal numbers.
Also used with the [Inch] and [/] keys for entering Feet-
Inch-Fraction values (e.g., 6 [Feet] 9 [Inch] 1 [/] 2).
Repeated presses during conversions toggle between Feet-
Inch-Fractions and Decimal Feet.
[Inch] — Inch Key
Enters or converts to inches. Entry can be whole or decimal
number. Also used with the [/] key for entering fractional
inch values (e.g., 9 [Inch] 1 [/] 2). Repeated presses during
conversions toggle between Fractional and Decimal Inches.
[ / ] — Fraction Bar Key
Used to enter fractions. Fractions can be entered as proper
(1/2, 1/8, 1/16) or improper (3/2, 9/8).
[Met] — Meter Key
Enters or converts to meters.
Entering Square or Cubic
To label a dimension as “square” or “cubic,” enter the
value, then press the desired dimension key twice for
square and three times for cubic. For example, to enter
25 cubic yards, press 25 [Yds] [Yds] [Yds].
Fraction Resolution
Your calculator is set to display fractional values to the
nearest 16th of an inch (default setting). The 1/16 resolution
can be displayed by pressing [Rcl] [/]. Repeated presses of
[/] will then revolve through the available settings: 1/16, 1/32,
1/64, 1/2, 1/4 and 1/8. The setting that you last see on the
display will be permanently set when you exit this mode
(simply press any other key to exit). To change the setting,
repeat the key sequence above and select your desired
fractional resolution. To recall your setting at any time,
press [Rcl] [/].
Your calculator will also toggle between the highest fractional
resolution available and the set resolution with repeated
presses of the Fraction Bar [/] when a fraction is displayed.
See the example below:

[÷] 64 [=] 1/16 INCH
[ / ] 3/64 INCH
[ / ] 1/16 INCH
Project Keys
The following keys help you quickly estimate material
quantities for common DIY projects. In addition, the [Stor]
key allows you to set material values to other than the
industry standards currently stored in the calculator (i.e.,
you may replace the default values).
Note: To view Examples on how to customize Project Key
settings using the [Stor] key, see “Project Examples–
Using Custom Settings.”
[Paint] — Paint
Computes volume of paint, based on an entered area and a
stored Paint Coverage per Gallon (see below). Finds quan-
tity in gallons, quarts or pints upon repeated presses.
[Stor] [Paint] — Stores Paint Coverage

Note: Tile sizes are shown in inches, not square inches (as
used in custom tile size calculations). In other words, a 6”
tile is really 6” x 6,” or a 36 square-inch tile, but it is
labeled as a 6” size.

press [Rcl] [1].
[Conv] [2] — Brick
Computes the number of standard 8-inch-size U.S. bricks
(with 3/8” mortar) based on entered linear distance (or
area, volume). Finds values for both “face” (21-square
inch) and “paver” (32-square inch) brick applications. By
pressing [2] again in succession, it will toggle back and
forth between “face”, “paver” and entered value.
[Conv] [3] — Block
Computes the number of standard 128-sq.inch blocks (with
1/2” mortar), based on an entered linear distance or area
and a stored Block Area (see below).
[Stor] [3] – Stores Block Area
Stores Block Area in square inches. To recall this setting,
press [Rcl] [3].

settings or material sizes. However, you can change most
of these settings at any time.

clear upon turning your calculator off until you change them
or reset the calculator). So be sure to check the stored val-
ues using the [Rcl] key prior to completing new problems,
and set new values if needed using the [Stor] key.
