Robert Kaufman Fabrics and Quilter's Paradise have joined forces to bring you a collection of eight essential quilting calculators.

With these calculators you'll be able to quickly convert between yards and inches, meters and centimeters; learn how much fabric you need for backing, batting and borders; and determine how many rectangular pieces can be cut from a larger piece. There are even calculators for square-in-a-square, set-in and corner triangles.

Here's a brief description of each calculator:

Fabric Measurement Converter: Converts between inches and yards in decimal form, and yards in fractional form. (With metric equivalents.)
Backing and Batting Calculator: Determines how much material from a bolt of fabric is needed to make the backing for a quilt.
Piece Count Calculator: Shows the number of fixed-sized pieces of fabric that can be cut from a larger piece.
Pieces to Area Calculator: Indicates how much fabric is needed in order to cut a given number of fixed-sized pieces.
Binding Calculator: Tells you the amount of fabric required to bind your quilt, based on the quilt’s dimensions and the binding strip width.

Border Calculator: Shows the amount of fabric required to create borders, based on a quilt’s dimensions and the width of the borders.

Square-in-a-Square Calculator: Works out the key dimensions of a square-in-a-square block.

Set-in and Corner Triangle Calculator: Determines the size of the square piece you’ll need to cut in order to create both unfinished set-in triangles and unfinished corner triangles.

I use the app mostly to figure out how much fabric to buy for backing, batting & binding. It's easy to use. One thing would make it better...the ability to convert from imperial to metric without the app going back to the beginning and losing all the data already entered. I'm from Canada, and the quilting patterns I follow are in inches, but fabric stores sell in metric (meters & centimeters). It would be great if I could enter my quilt dimensions in inches and convert to metric with one button.
