Standalone calculator preview

This page previews the calculator assets outside Joomla. It is not a hosted native Joomla demonstration. Starting values are synthetic examples; inputs are neither stored nor submitted.

Sewing measurement lab

Check units, observed fabric size changes and the two axes of a printed pattern independently. The starting values are illustrative examples.

Unit conversion Value From unit To unit

Observed fabric dimension change

Enter one axis before and after washing in the same unit. A positive change means shrinkage; a negative change means expansion. Measure the other axis separately.

Before washing After washing

Independent print-axis check

Use the same unit for all four dimensions. These ratios describe the observed print; they do not select a printer correction or a pass/fail tolerance.
