    Default chain...18/18, 48/4...whats it mean?

    looking at curb chains, they are described as 18/18 or 48/4 or 62/3...can u explain what this means..is it useful in designing pieces, such as tightness of knit etc?

    Hi,
    The first number represents the diameter of the wire, the second number is the number of links to the inch.
    So 18/18 is made from 0.018" diameter wire and there are 18 links per inch.
    Hope this helps.
    Dave

    Thank you! I knew the second one, but had been trying to turn the first into some sort of gauge, not a fractional inch measurement! That's going to save a lot of mistakes

    Default Thanks dave !

    As a handy guide, here's a list of what those numbers mean in mm wire size:

    cooksons number, then its approx MM Eqivelent.

    24 = 0.6mm wire
    28 = 0.7mm wire
    33 = 0.8mm wire
    40 = 1.0mm wire
    48 = 1.2mm wire
    62 = 1.5mm wire
    72 = 1.8mm wire
    85 = 2.1mm wire


    DID U KNOW.....'google' has an automatic calculator?
    You can type common expressions into the google search box and it calculates the answer! (eg. type in "2mm in inches" and hit enter)

    (see the google 'more' button, or help pages for other 'expressions' and short cut expressions/symbols allowed for this to function)

    Aaaah! I knew the second was links per inch but I thought the first was to do with the length of the individual links. Never seemed to make much sense so thanks for the enlightenment.
