not displayed in the above Total Quilt Yardage list.
***All calculated items include adjustments for
seam allowance, except for Binding (it is
assumed the seam allowance is included in the
stored Binding cut value used for calculating
Binding Yardage and number of strips).
Note: Entries of Top Width, Top Length, Border,
and Drop are semi-permanent entries; that
means, they do not clear until you turn off your
calculator or until you enter a new value. You
can enter zero to clear these values if you have
previously stored values.
Page 16
U
SER’SGUIDE
— 12
Top and Backing Yardage
Top and Backing Yardage are calculated based on a linear, or “running”
method for laying out the quilt. This
means the Length of each strip (or
“run”) is based on the Length of quilt,
and the number
of runs needed is
based on the Width of the quilt.
In the diagram above, the layout
shows three runs (two runs that are
40” wide and one run that is 18”
wide). The Quilter ’s FabriCalc will
actually calculate Yardage for three
runs that are each 40” wide (2 1/2
Yards each), even though the actual
finished Width of the runs may vary.
It is calculated this way to allow plenty of material to lay out your top or
backing. Each run is uncut along the
(Cont’d)
Page 17
U
SER’SGUIDE
— 13
(Cont’d)
Length of the run (e.g., the strips run
the Length quilt without having to
piece material together).
If your top or backing strips are laid
out parallel to your Width, you can
switch your values on the Top Width
and Top Length keys in order to calculate the correct top and backing
Yardage and strip cut values for this
orientation (e.g., re-enter Top Width
as Top Length, and Top Length as
Top Width).
NOTE: If your quilt has a Drop included and you need to calculate Yardage for strips that are laid out widthwise, the Drop
and Backing will not be calculated correctly once you switch
your Top Width and Top Length values since the Drop does
not change to fit this different orientation. You will need to calculate your Drop before switching your Top Width and Top
Length values. Then switch (re-enter) your Top Width and Top
Length values and calculate your Top Quilt Yardage. To properly calculate your Backing with a Drop, you will need to add
the Drop Width to the Top Width and Top Length values and
re-calculate your Backing Yardage.

CALCULATING YARDAGE FOR
SQUARES, TRIANGLES,
AND DIAMONDS
The following keys are used to calculate the Yardage required for Squares,
1/2 Square Triangles, 1/4 Square
Triangles, and Diamonds (45˚ and 60˚).
Additionally, these keys can also be
used to calculate the quantity that can
be cut from a given size of fabric. For
example, if you have a Yard of fabric,
you can calculate how many Squares,
Triangles, or Diamonds can be cut
from that piece of fabric.
Note: These are “smart” keys that allow you to
enter a unitless value, a Length, or an area. If a
Length is entered, the fabric area is calculated
based on the stored Fabric Width and they calculate a quantity. If a unitless value is entered,
this entry is assumed to be the Number of
Squares and they calculate the Yardage
required.
ß
Enters the Length of a Square’s size
(e.g., enter 2 i ß to store a
2 Inch x 2 Inch Square size).
Note: Square size is a semi-permanent value
(that means, it does not clear until you turn off
your calculator, or until you enter a new value).

FABRIC STORAGE
Your calculator has six individual, cumulative registers for storing up to six different types of material Yardages. You
can easily calculate various Yardage
requirements for each type of fabric you
are working with and store them in the
fabric registers. This provides the flexibility of storing various Yardages for a
particular fabric.
In addition, the total of these storage
registers is viewable via the Total Fabric
function. You can easily view your accumulated fabric Yardage so you know
how much material you will need to
complete your entire quilt project.

will assume the previously stored
dimension).
You can recall stored values, calculate
the average of all the stored values,
and display the total number of entries
that have been stored in memory.
M — Memory Plus
Adds any displayed number,
dimensioned or unitless, to the semipermanent, cumulative Memory.

between Inches, Centimeters, and Millimeters. If you
are converting from area values (e.g., Square
Inches, Square Centimeters, or Square Millimeters)
to linear values (e.g., Yardage and Meterage), the
area values are converted to linear values based on
the stored Fabric Width. If you attempt to convert
back to Inches once the value has been converted
to a linear value, it remains as a linear value and
converts to Inches based on the value that resulted
from the linear conversion to Yardage (or Meterage).

APPENDIX C – IMPORTANT NOTES
FOR OWNERS OF PREVIOUS
FABRICALCS
If you are an owner of a previous Quilter’s
FabriCalc calculator, the following list will
help you compare several enhanced
features.
Quilt Ydg Function (Top/Backing)
The calculation for Top and Backing
Yardage (part of the Quilt Yardage function) is now based on a linear, or “running”
method, for layout out your quilt. This
means the Length of each run is based on
the Length of quilt, and the number of runs
needed is based on the Width of the quilt.
It is calculated this way to allow plenty of
material to lay out your Top or Backing so
that each run is uncut along the Length of
the run (e.g., the strips run the Length of
the quilt without having to piece material
together).
Cost Function
The Cost function now bases it’s calculation on the displayed (or entered) fractional value rather than the underlying
decimal value (as in the previous version
1.0). In many cases, the fractional
Yardage value has been rounded up to
the nearest fraction. If you wish to calculate the Cost of material based on the
actual decimal value that was calculated,
(Cont’d)
Page 63
U
SER’SGUIDE
— 59
(Cont’d)
you may convert the displayed fractional
value to the actual decimal value (for
instance, c y will convert the fractional Yardage to decimal Yardage) and use
the decimal value to calculate the cost
per Yard (or Meter).
Square Size Function
It is no longer necessary to press c
ß to view the Square Diagonal.
Repeated presses of the ß button
now toggle between the Square Size and
the Square Diagonal.
Fractional Rounding
Decimal values can now be rounded to
the nearest “Quilter’s” fraction by pressing c /. With a displayed decimal
value (Yardage, Inch, or unitless value),
pressing c / will convert this value to
the nearest fractional value and modify
the underlying decimal value to correlate
with the displayed fractional value.
Yardage values will be rounded up to the
closest fractional value if the decimal
Yardage value exceeds the closest fractional equivalent by 0.01 Yard.
This feature is useful if you are working
with or storing rounded, fractional values.
The Quilter’s FabriCalc displays Yardage
calculations in the closest fraction, even
though the actual decimal value may not

match this rounded, fractional value. For
instance, when calculating Yardage for
20 five-inch squares, the displayed fractional Yardage is 1/2 Yard, even though
the actual decimal value of this calculation is .45833 Yards. The Quilter ’s
FabriCalc rounds up to the nearest fraction so that you purchase the proper
amount of material in standard, fabric
fractions.
When storing the displayed 1/2 Yard in
any of the memory registers (such as
FAB-1), the actual decimal value is
stored. The calculator will add the decimal values of any additional Yardages
that are added to the cumulative memory
registers, so the cumulative result will
display to the nearest fraction based on
the underlying decimal value.
For example, if you calculated 1/2 Yard
for 20 five-inch Squares and stored it in
Fabric 1, and then calculated 40 five-inch
Squares (result: 1 Yard) and added the
resulting 1 Yard to Fabric 1, your total
Fabric 1 result is 1-3/8 Yards (not 1-1/2
Yards) because the underlying decimal
value is used. This helps you buy the
correct quantity of material so you don’t
buy too much.

You can modify the decimal yardage
value to match the displayed, rounded
fractional Yardage value by pressing c
/. In the example above, calculating
Yardage for 20 five-Inch Squares and
pressing c / would change the calculated decimal value (.45833) to match the
displayed 1/2 Yard (.5).

APPENDIX D – OPERATING
INSTRUCTIONS
Please follow the guidelines listed in this
section for proper care and operation of
your calculator. Not following the instructions listed below may result in damage
not covered by your warranty. Refer to the
Repair and Return section for more
details.
Do not expose calculator to temperatures
outside the operating temperature range
of 32ºF – 104ºF (0ºC – 40ºC).
Do not expose calculator to high moisture
such as submersion in water, heavy rain,
etc.
BATTERY
Your calculator is powered by a single 3Volt Lithium CR-2016 battery. This should
last approximately 800 hours of actual use
(1 year plus for most people). Should the
display become very dim or erratic,
replace the battery.

APPENDIX E – ACCURACY, ERRORS
AND AUTO SHUT-OFF
Accuracy/Errors
Accuracy/Display Capacity – Your calcu-
lator has a seven digit display. You may
enter or calculate values up to 9999999.
Each calculation is carried out internally to
twelve digits.
Your calculator is designed to calculate
Yardage up to the nearest allowable fraction. In most cases, Yardage calculations
will be displayed to the next available fraction so you calculate enough material (no
shortages). Your calculator will, however,
round down if the calculation is less than
0.01 to the nearest available fraction.
Fractional Inches are rounded to the nearest fraction.
Errors – When an incorrect entry is made,
or the answer is beyond the range of the
calculator, it will display the word
“ERROR.” To clear an error condition you
must press the N button once. At this
point you must determine what caused the
error and re-key the problem.
Error Codes
DISPLAY ERROR TYPE
OFLO Overflow (too large)
DIV Error Divide by 0
DIM Error Dimension error

SER’SGUIDE
— 65
DISPLAY ERROR TYPE
ENT Error Invalid entry error
TYP Type error
FABRC Error Fabric error*
* Block or square height (with seam) exceeds
fabric width
Auto-Range – If an “overflow” is created
because of an input and calculation with
small units that are out of the standard
seven digit range of the display, the
answer will be automatically expressed in
the next larger units (instead of showing
“ERROR”) – e.g., 10,000,000 mm is shown
as 10,000.00 m. Also applies to Inches
and Yards.
Auto Shut-Off
Your calculator is designed to shut itself off
after about 8-12 minutes of non-use.
