The ProjectCalc®Classic was designed specifically for
home decorators. It’s an indispensable tool for all your
home decorating projects! It helps you quickly figure
project material quantities and costs for paint, tile and
wallpaper, as well as linear distances, areas/volumes.
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:
• Tile
• Paint
• Wallpaper
Basic Keys
o — On/Clear Key
Turns power on. Pressing once clears the display.
O
Turns all power off.
+ – x ÷ =
Arithmetic operation keys.
%
Percent key.
0 — 9 and •
Keys used for entering numbers.
/ — Fraction Bar Key
Used to enter fractions. Fractions can be entered as 1/2,
1/16, 3/2, etc.
KEY DEFINITIONS

Convert Key Functions
Ç — Convert Key
Used with the dimensional unit keys to convert between
dimensions (e.g., feet-inches to yards), the decorating
keys to calculate material quantities, or with other keys
to access special functions.
Ç – — Sign (+ / –)
Sets value on display to plus or minus. (Repeated presses
of Ç – will change sign from plus or minus.)
Ç ÷ — Square Root
Finds square root of value in display.
Ç x — x
2
Finds square of value in display.
Ç % — Pi (π)
Constant 3.141593
Ç • — Cost
“Cost” function that allows you to compute total material
cost, given a unit dimension and an entered Per Unit Cost.
Memory
Ç + — M+
Adds or stores a value in the cumulative memory (e.g.,
1 5 0 Ç +). Semi-permanent means the value is
cleared when the calculator is turned off.
Ç = — MR
Recalls memory value (e.g., if 150 has been stored in
Memory, pressing Ç = will display 150).
Ç o — MC
Clears memory value.

Dimensional Unit Keys
y — Yards Key
Enters or converts to yards.
f — Feet Key
Enters or converts to feet as whole or decimal numbers.
Also used with the i and / keys for entering FeetInch Fraction values (e.g., 6 f 9 i 1 / 2).
Repeated presses during conversions toggle between
Feet-Inch Fractions and Decimal Feet.
i — Inch Key
Enters or converts to inches as whole or decimal numbers.
Also used with the / key for entering fractional inch
values (e.g., 9 i 1 / 2). Repeated presses during
conversions toggle between Fractional and Decimal Inches.
m — Meter Key
Enters or converts to meters.
Entering Square or Cubic
Dimensions
To label a dimension as "square" or "cubic," enter the
value, then press the desired unit key twice for square
and three times for cubic. For example, to enter 25 cubic
yards, press 2 5 y y y.

Fractional Resolution
Your calculator is set to display fractional values to the
nearest 16th of an inch (default setting). The current
fractional resolution can be displayed by pressing Ç
/. 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 you last see on the display will be permanently set when you exit the fractional setting display
(simply press any other key to exit).
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.
Decorating Keys
The following keys help you quickly estimate material
quantities for common decorating projects. Note: if you
clear the display (i.e. press o) and then press one of
the decorating keys, the conversion factor will be displayed. For example, pressing Ç 8 (Wallpaper) after
clearing the display will show the area of coverage for
one roll of Wallpaper.
Ç 7 (Paint)
Calculates volume of paint, based on an entered area.
Finds quantity in gallons, quarts, or pints with repeated
key presses.
Ç 8 (Wallpaper)
Calculates number of rolls of wallpaper, based on an
entered area.
