I am going to crochet a table runner 96 inches long. My pattern calls for 750 yards for 52 inches. The crochet cotton is measured in grams each is 10 grams. How can I calculate how many balls to buy?

Unfortunately you can't convert grams (weight) to yards (length). If you can get the yardage in the 10 gram balls of cotton then you can divide that number into 750 to find out how balls you will need.

Thank you for your reply. I do have the telephone # for Yarn Bazaar and will call them on Monday. Hopefully they will have the answer I need.

Sometimes I'm able to find out the yardage by Goggling it on the computer: asking the question "How many yards are in...adding your grams and the name of the yarn.

There are 28.5 gms/1 oz. If you can work out the yardage this way. I believe there are 16 ozs to 1 lb, There are 36" = 1 yard. I don't know of all the measures to change from ozs to lbs, to yards.

Maybe some more experienced person than I can help solve this.

While you CAN convert grams to yards it's not an exact science. Cotton is a heavier fiber than others so the conversion charts will not be exact. Generally a lace weight yarn will contain 8.8 yds (9 meters) per gram, though crochet thread isn't exactly lace weight but this would give you a very rough estimate.

Years ago I came across a conversion chart for grams to yards for yarns from lace weight to super bulky. Many times I've been glad I saved and laminated it.

Thank you all very much! If I use 9 yards per 10 gram ball I will buy 14 balls. this gives me extra thread. I would rather have to much than not enough. My daughter wants this runner to be 96 inches. the below link should show you the runner I will be making. if is from Annie's Attic the book "More Table Runners" (in half the time) it is the purple runner a (basket of flowers is on the table) After reading this pattern it will be in twice the time rather than half the time. I may be asking for help for this pattern

if you tell me how many yards in each ball. i will calculate for you. what's the mesurements for the runner (lenght and width)?

You cannot convert grams to yards because a gram is a weight measurement (ounces) and yards is a length measurement. How many yards per gram would depend on how thick the yarn or cotton is, just as figuring out how many yards there is per ounce. Does the ball of cotton show how many meters there is? There is approx 1.09 yards per meter. So a meter is a little bit longer than a yard (approx. 3 inches). If it shows how many meters on the ball you can go by this, or you can go on google and find hundreds of conversion charts and devices.

No there is only the grams on the ball of yarn and yards in the pattern

wouldn't the metre or yardage be quoted on the label? - that is what they do for knitting yarn at least - it is not always written in an obvious spot on the label and you may need to search for it though.

If you look on the website of the company who sells the yarn, sometimes it will tell you how many yards the yarn has. I've done that before. then divide like someone else said.

Knitnut, there are conversion charts for converting grams to yards!!!! It is only an approximate but can be a useful guide for rough estimates.

Lace weight yarns contain an average of 8.8 yds or 9 meters per gram. Cottons will have less yards per gram because it is a "heavier" fiber, while mohair or angora will yield more yards per gram because they are lighter.

Here are the conversions:

Lace 8.8 yds (9 m)/gram
Fingering 4.4 yds (4 m)/gram
Sport 2.75 yds (2.5 m)/gram
DK 2.5 yds (2.25 m)/gram
Worsted 2.2 yds (2 m)/gram
Heavy Worsted 1.65 yds (1.5 m)/gram
Bulky 1.1 yds (1m) gram
Super Bulky 0.8 yds (0.75 m)/gram

You may be able to go to Yarn Bazaar online, search out your cotton yarn, and look at their description...usually they will give weight and yardage.
Another way to do the math would be to see how many balls the original pattern called for to make a 52" runner, say 9 balls. You want your finished project to be 44" longer, or 96" so you can find what you need this way.
First, in plain english, think, if I need (say) 9 balls to make 52 inches, I'm gonna need x balls to make 96 inches.
then you turn it into an equation: 9:52=x:96...9 balls are to 52 inches as x balls are to 96 inches.
then multiply 9 times 96 and divide the result by 52. The answer will be the total number of balls you'll need for the project. (It will probably be a fraction, so round up one ball.)

I often tell my students that the dirty little secret about knitting is the amount of math involved, but it's pretty powerful for solving problems. Hope this helps you forever.

I use this site to calculate grams to ounces or cm to yards:
I know this site is for businesses but they put it there, so why not use it?!
