LUS MX
The
ProjectCalc Plus®MX
was designed specifically for DoIt-Yourselfers in the United Kingdom and other countries that
use Metric measurements. 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 Metric measurements and can also
convert to Imperial (feet-inch) units, including Square and
Cubic, so you don’t have to figure tedious maths.
Use it to estimate quantities and costs for:
• Bricks & Blocks • Paint
• BTUs • Slabs (Patio)
• Concrete & Gravel • Studs
• Drywall • Tile
• Flooring (Carpet/Vinyl) • Wallpaper
The
ProjectCalc Plus MX
is an indispensable tool for all
your home Do-It-Yourself projects!

Basic Keys
o — On/Clear Key
Turns power on. Pressing once clears the display.
Pressing twice clears all temporary values.
Ç o — Off
Turns calculator off and clears all temporary/non-permanent registers.
r — Recall Key
Recalls stored values. Also works with Memory keys (see
Memory keys for details).

0 — 9 and •
Keys used for entering numbers.
Convert Key Functions
Ç — Convert Key
Used with the dimensional unit keys to convert between
dimensions (e.g., cubic millimetres to cubic metres), with
the “Project Keys” to calculate various material quantities
(see
“DIY Project Keys”
), or with other miscellaneous keys
to access special functions, such as those listed below.
Ç x — Clear All
Clears all values, including memory. Sets the calculator back
to its default settings. Use this keystroke with caution, as it
will reset all custom settings or stored material values.
Ç – — Sign Change
(+ / –)
Sets displayed value to positive or negative. (Repetitive
presses of Ç – will change sign to plus or minus.)
Ç ÷ — Square Root
( )
Finds square root of displayed value (e.g., 1 0 0 Ç
÷ equals 10).
Ç + — x
2
Finds square of displayed value (e.g., 1 0 Ç +
equals 100).
Ç s or r s — Pi
(π)
Displays the constant 3.141593

Ç 8 — Percent
(%)
Memory
Ç =
(M+)
— Adds the displayed value to the semipermanent memory register (e.g., 1 5 0 Ç =).
Semi-permanent means the value is cleared when the
calculator is turned off.
r =
(M-R/C)
— Recalls memory value (e.g., if 150
has been stored in Memory, pressing r = will display
150).
Note:
This function displays, but does not clear, the
memory register.
r r
(M-R/C)
— Displays and clears/deletes any
value stored in the memory register.
Ç o
(Off)
— Turns calculator off and clears the
memory register.
s = — Memory Store (replaces stored memory
value with the displayed value).
Measurement Unit Keys
m
Enters or converts to metres.
M — Millimetres
Enters or converts to millimetres.
Ç 7
(cm)
— Centimetres
Enters or converts to centimetres. For example, to enter
50 centimetres, input 5 0 Ç 7.
f
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 swap between FeetInch-Fractions and Decimal Feet.
i
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 i 1 / 2). Repeated presses during
conversions swap between Fractional and Decimal Inches.
ProjectCalc®Plus MX User’s Guide — 3
/ — Fraction Bar
Used to enter fractions (e.g., 1-1/2 inches is entered 1
i 1 / 2).
Note:
You need to assign the “whole”
inch value (e.g., 1 i) first using the i key, then
enter the fraction (1 / 2). However, if you are only
entering fractions of an inch, you don’t need to assign it,
the calculator knows it is a fractional inch if you use the
/ key—e.g., enter 1/8 of an inch by pressing 1 / 8.
Fractions can be entered as proper (1/2, 1/8, 1/16) or
improper (3/2, 9/8).
Ç 9
(Yds)
— Yards
Enters or converts to yards. For example, to enter 50
yards, input 5 0 Ç 9.
Entering Square or Cubic Values
To assign a measurement 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 square metres, press 2 5 m m. To enter 25
cubic metres, enter 2 5 m m m.
Fraction Resolution (for Imperial
Measurements Involving Fractions)
Your calculator is set to display fractional values to the
nearest 16th of an inch (default setting). The 1/16-inch
resolution can be displayed by pressing r /.
Repeated presses of / will then revolve through the
available fractional inch 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).
Your calculator will also swap 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:

DIY (Do-It-Yourself) Project Keys
The following keys help you quickly estimate material
quantities for common DIY projects. In addition, the s
key allows you to change material values for selected
functions (i.e., you may replace the “default values” with
your own). Note that these changes are stored until you
change them again, or perform a “Clear All” by pressing
Ç x.
Note:
To view Examples on how to customize Project Key
settings using the s key, see
“Project
Examples–Using Custom Settings.”
p
Calculates quantity of paint in litres, based on an entered
area and a stored Paint Coverage Area per Litre.
s p — Stores Paint Coverage Area Per
Litre
Stores a new Paint Coverage per Litre (see grid,
“Default/
Standard Values for Materials,”
for current setting). To
recall your setting, press r p.
w
Calculates number of rolls of wallpaper, based on an
entered area and a stored Wallpaper Roll Coverage Area.
s w — Stores Wallpaper Roll Coverage
Area
Stores a new Coverage Area per Wallpaper Roll. To recall
this setting, press r w.
t
Finds the number of tiles, based on an entered length or
area. Repeated presses will scroll between numbers of
ProjectCalc®Plus MX User’s Guide — 5
tiles based on various Standard Tile Sizes (see
“Default/
Standard Values for Materials”
).
Note:
In the calculation,
the corresponding tile size will show in the upper right of
the display. Tile sizes are labeled in millimetres, not
square millimetres (or sq. metres). In other words, a
“100mm tile” is really 100mm x 100mm or a 10,000
square-mm (0.01 sq. m) size.
Note:
Calculation does not account for grout width, so
you will need to adjust for this.
Also note that this key cannot be customized; you must
use Custom Tile Keys Ç 6 if you are using other than
the stored tile sizes.
F
Calculates carpet length required in metres based on
entered area and Standard Carpet Roll Sizes (see
“Default/Standard Values for Materials”
). Repeated presses
of F will scroll between standard roll sizes.
Note:
this
key cannot be customized.
b
Calculates the number of standard “face” bricks and
“paver” bricks based on an entered length, area or volume and the Standard Brick Sizes. Repeated presses of
b will swap back and forth between the number of
“face” and “paver” bricks, and the entered dimensional
value.
Note:
this key cannot be customized.
Ç 4 — 8 x 4 Sheets
Calculates number of plywood/drywall sheets based on an
entered linear distance or area and Standard Sheet Sizes
(see
“Default/Standard Values for Materials”
).
Note:
this
key cannot be customized
Ç 5 — Bulk Bags
Calculates number of bags of gravel or sand based on an
entered volume and a stored Bulk Bag Size.
s 5 — Stores Bulk Bag Size
Stores a new Bag Size.
Note:
You must enter or find the
bag’s cubic volume first. Use length x width x height, then
s 5. To recall this setting, press r 5.
ProjectCalc®Plus MX User’s Guide — 6
Ç 6 — Custom Tile
Calculates number of tiles based on an entered area and a
stored Custom Tile Size. This is used separately from the
regular t key, which has various Standard Tile Sizes
built in.
Note:
Calculation does not account for grout width for
custom tiles, so you will need to adjust for this.
s 6 — Stores Custom Tile Size
Stores Custom Tile Size. You must enter or find the tile
size area first. Use length x width, then s 6. To recall
this setting, press r 6.
Ç 1 — Slabs (Concrete)
Calculates the number of slabs of concrete required,
based on an entered length or area and Standard Slab
Sizes.
Note:
this key cannot be customized.
Ç 2 — Studs

distance and a stored On-Centre Spacing.
Note:
Automatically adds one stud to the calculated
answer to account for one on the end.
s 2 — Stores On-Centre Spacing for Studs

recall this setting, press r 2.
Ç 3 — Blocks
Calculates the number of blocks based on an entered linear distance or area and a stored Standard Block Area.
