How to Calculate The Length of a Yarn the Easy Way

The label on the yarns usually says the weight and the length in each ball. But what if you are using some left over yarns or yarn stashes and had no idea of the length of them while your project says you need a certain length to complete?

Well here is the easiest and quickest way to find out. All you need is a tiny amount of yarns cut from the ball you wish to calculate and a digital pocket scale which is available at Amazon.com from under USD10. If you have no access to Amazon, check for it at shops which sells jewelry supplies. This tiny scale usually can measure the weight up to 100grams. The reason why we use the pocket scale is because it is used to measure the weight of jewelries and the accuracy is very close to the actual weight, and secondly we don't have to cut such a long thread to measure.

The scale in the picture above indicates that the weight of the yarn which is 1 gram.

Now let measure this tiny yarn and see what we get. It says 45 in or 114.3 cm.

Now let check the weight of our stash... It says 19 grams. It means the length of the yarn is 

19 x 114.3 cm = 2,171.7 cm = 21.8 M  or 23.75 yards.

Now let's try with different thickness of yarns. The previous yarn was a Light Worsted yarn. This one now is a thicker yarns, also came without label. All I know is the ball when it was new was 100 grams.

The scale says 1.26 grams, 

and it measures 55.2 inches

This ball ball is 49.25 grams

Now let's do the math: 1.26 grams = 55.2 inches

1 gram = 55.2 : 1.26 = 43.8 inches

49.25 grams = 49.25 x 43.8 = 2,157 inches

---> round it off to the nearest 10 inches=2160 inches

2160 : 36 inches (1 yard) = 60 yards.

Easy peasy right?
