Two figures in, a clear answer out. The paper weight calculator uses basic length, new basic length, basic width, new basic width, basis weight (of a ream), converted basis weight (of a ream), length, quantity and width to produce weight per sheet, new basic area and paper grammage, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Paper Weight Calculator?
The paper weight calculator turns basic length, new basic length, basic width, new basic width, basis weight (of a ream), converted basis weight (of a ream), length, quantity and width into weight per sheet, new basic area and paper grammage.
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 Paper Weight 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 basic length set to 10, new basic length set to 5, basic width set to 2, the calculator returns paper area of 0.0129, and basic area of 20, and new basic area of 500. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out weight per sheet?
Enter basic length, new basic length, basic width, new basic width, basis weight (of a ream), converted basis weight (of a ream), length, quantity and width. The calculator then works through the relationship and reports weight per sheet, new basic area and paper grammage.
What does the paper weight actually calculate?
It takes basic length, new basic length, basic width, new basic width, basis weight (of a ream), converted basis weight (of a ream), length, quantity and width and converts them into weight per sheet, new basic area and paper grammage 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 basic length?
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.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
