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
KEY DEFINITIONS
Basic Keys
o — On/Clear Key
Turns power on. Pressing once clears the display.
O
Turns all power off.
+ – x ÷ =
Arithmetic operation keys.
%

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 — x2
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.
