Free Online Crochet Calculators and Conversion Charts

If you’ve found yourself reading this page, I’m guessing that you love to crochet. 

Like me, working with that hook and yarn is the part you love most; calculations and conversions that involve working math are a necessary annoyance, right?  

Not anymore! 

On this page, we have many links to free online sites with crochet calculators, charts, and conversions.

You’re going to love the links to the crochet hook conversion charts, crochet blanket sizes, yarn yardages, and many more useful crochet tricks.

CROCHET HOOK CONVERSION

Many of you have asked for links to crochet hook conversion charts that will convert crochet hook sizes from standard to metric.  We have one for you, and it even converts knitting needles; an added bonus!!

CROCHET BLANKET SIZES CHART AND CALCULATOR

Have you ever wondered how big the size of your corner to corner blanket will be?  We found a link to a C2C blanket calculator that will do all of the math for you after you crochet a SMALL swatch. 

The calculator will determine the size based on your own gauge, yarn, and hook size!  

Another chart will help you determine the number of crochet stitches you will need for your C2C blanket based on the desired size of your finished project.

There are other helpful charts, giving you the size of crochet blankets from baby lovies to king size bed blankets.  Don't worry; they also have every other blanket size in between!

Thank you to those who love math!!

INTERNATIONAL CROCHET HOOK AND STITCH CONVERSION CHARTS

Interestingly, basic crochet stitches have different names in the UK and US.  Below you will find a link to a crochet stitch conversion chart.

Be sure to look at your pattern or the location where the pattern or book was published to determine whether the pattern is using UK or US terminology. The various names for the same stitch can become quite confusing for beginners.

CALCULATING CHAINS

You will also find another calculator that will allow you to choose any stitch you’d like to use in a project and enter the desired size of your finished project.  You’ll have to enter the stitch multiples, extra turning chains, and the foundation chain requirements, and then the calculator will tell you how many chains are needed to begin your project.

This calculator is great for designers, but many others may find it useful as well.

Let these great crochet calculators and charts do the work for you!! 

You will also want to be sure to check out our other calculators and charts for knitting and sewing!

Enjoy!!
