There is no standard.
From Wikipedia:
"Hanks come in a fixed length depending on the type of material, so the term
hankis sometimes used as a unit of measure. For instance, a hank of
linenis 270 metres, and a hank of
cottonor
silkis 768 metres. In
beads, 1 hank = 3.333
fathoms= 6.667
yards= 20 feet = 6.096 metres."
A particular length of thread or yarn conforming to the kind of fiber is called a hank. For linen, it is 274 meters (300 yards). For cotton, a hank is 768 meters (840 yards).
A skein is the small bundle one would buy at a craft store.A hank is a bundle of skeins. Defined as follows:a traditional measure of length for yarn. The length of yarn in a hank varies with the market and the material; for example, a hank of cotton yarn traditionally included 840 yards (768 meters) of yarn, while a hank of wool yarn was 560 yards (512 meters). For both cotton and wool, these traditional hanks are equal to 7 leas or to 12 cuts. In the U.S., however, a hank of woolen yarn is generally 1600 yards (1463 meters). In retail trade, a hank is often equal to 6 or 7 skeins of varying size.(http://www.unc.edu/~rowlett/units/dictH.html#hank)

Unfortunately, there are no standards for amounts of yarn, which can come in various forms: balls; skeins; hanks; cones are terms which come to my mind quickly. I would say that in my mind, a ball would have less yarn than a skein, which would have less yarn than a hank, and what would generally have the most yardage, would be a cone00but those are MY distinctions, based upon absolutely NOTHING, just how I use the words, unless I am referring to a specific form of a particular yarn. So, for you to find out how much yarn is in a hank, you would have to look at the specific brand of yarn, and read (on the "ball band," the paper band which encircles the hank, or the tag attached to the hank of yarn), and read the actual yardage of that particular yarn hank. Also, be aware that just because Company A had 350 yards of yarn for one variation of their yarn, that all hanks would have 350 yards--it not necessarily true. The other variations could have any amount of yarn in a hank. Therefore, you would need to read the ball band, or tag on the hank to get the amount of yarn in that particular hank, or you could go to the manufacturers website and see if they list how many yards are in the hank. By the way, there are brands, and yarns that are sold that only give the amount in that form of yarn in ounces--no yardage given! Now, that can be fun to convert into approximate yardage!
