Is it pronounced as one-by-one or as one-to-one when read out?

Please note that this use is related to the binding structure of textiles.

Here is an example of usage from Role of Yarn Tension in Weaving by Samir Kumar Neogi (©2016):

It is observed that when the weave is changed from 4 / 1 satin to 1 / 4 satin, the average warp tensions at shedding and beaten-up increase (Fig. 7 .38A )

    It might help if you provide a link for some context. Do you mean like what's happening here or here?

    Hi dasliit and welcome to Stack Exchange. I thank you for heeding my advice. Now I hate to be a bother, but I just wanted to mention that here at Stack Exchange, we have certain requirements for making quotations. In addition to properly delimiting the quotation, as you have, you should also include at least the name of the source material, and its author, in plain text (since links break). I took the liberty of fixing this for you with an edit, but I thought I'd expressly inform you of this anyway, just for the sake of future reference.

It is best to use what the slash is normally used for which is fractions or more specifically ratios. The sentence can be read as "the weave is changed from 'four to one' satin to 'one to four' satin". The ratio of A to B is what the text is about. The slash has just been used as shorthand.


This sounds like a ratio of one-to-one or one-to-four or whatever. In plain textual writing, I'd write it out that way. If it's technical writing, the slash construction is fine, as long as that's what the particular industry conventionally does. Beware, though, of using technical contractions like that in "standard" writing for ordinary civilians and normal people.
