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 it calcu-
lates a quantity. If a unitless value is entered,
this entry is assumed to be the Number of
Squares and it calculates 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).
c ß
Displays or enters the diagonal of a
Square (e.g., 7 i c ß).
s
Calculates the Yardage required
based on an entered number of
Squares. Also calculates the number
of Squares that can be cut from an
entered amount (length or area) of
fabric.
