(It also depends on what it's made from and the shape of the links, but if we assume the material and the shape are identical, then a chain 1/2 the thickness will have 1/4 the strength.)  As it works out, weight scales likewise - a chain 1/2 the thickness but the same length will have 1/4 the weight.The "rated" strength is less than the "burst" strength - a chain rated for 2000 lbs means it can safely lift a 2000 lb load, so it probably breaks at around 2200 or so.  So if the "generic" chain has a break strength of 920 lbs it's probably "rated" for 850 or so.  That's about 0.425 the strength, so 0.425 the weight = about 5 lbs per 10' length.However, I suspect the weight for rope may be light as well.  Hemp rope is noticeably heavier, bulkier, and stiffer than modern nylon rope.</blockquote>
