Whether you are estimating on the spot or checking a result somebody else gave you, the quilt calculator is the quickest way to get from bolt of fabric width, fabric, length, additional overage, fabric needed for… and width to result1 back non case 3, pieces1 back non case 3 and result back non case 2.
What Is the Quilt Calculator?
The quilt calculator turns bolt of fabric width, fabric, length, additional overage, fabric needed for... and width into result1 back non case 3, pieces1 back non case 3 and result back non case 2.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Quilt Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with bolt of fabric width set to 10, fabric set to 0, length set to 5, the calculator returns result back non case 2 of 224, and pieces back non case 2 of 2, and result1 back non case 3 of -. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out result1 back non case 3?
Enter bolt of fabric width, fabric, length, additional overage, fabric needed for... and width. The calculator then works through the relationship and reports result1 back non case 3, pieces1 back non case 3 and result back non case 2.
What does the quilt actually calculate?
It takes bolt of fabric width, fabric, length, additional overage, fabric needed for... and width and converts them into result1 back non case 3, pieces1 back non case 3 and result back non case 2 using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter bolt of fabric width?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
