About StitchMath

StitchMath is a set of free calculators for knitters and crocheters. It handles the arithmetic behind gauge, stitch counts, shaping and yarn amounts so you can focus on the stitches.

Each calculator explains the method it uses so you can check the result and adapt it. Everything runs in your browser; nothing you type is sent anywhere.
