Yarn chicken can be a fun and exciting game, especially when you win.  Personally, I have lost yarn chicken more times that I can count. But I hate losing.  Really hate it.

Pin It Now, Use It Later

Still there must be a way to figure out exactly how much yarn is contained in those little leftover balls.

It turns out there is, it involves a bit of math, a little converting, more math and converting back.  Doable, but hardly simple or quick.  My crochet journal was starting to look more like an 8th grade math homework book.

The yarn calculator was born

The yarn calculator was created out of my desire to not have to scribble math formulas all over my crochet journal anymore and also know how much yarn I have.

Taylor Kitchen Scale from Amazon

The yarn calculator is based on weight and will help you figure out exactly how much yarn you’ve used or have left, in yards and meters.

To use the yarn calculator is pretty simple.  You need 3 things:

  1. The original yarn label or Google if you know the brand but no longer have the label
  2. A scale.  I use this simple kitchen scale (affiliate link) from Amazon
  3. The yarn you want to use.

I really hope the yarn calculator helps you figuring out how much yarn you have and saves your crochet journal from math scribbles.
