How do I figure out the weight in ounces of a cloth that is listed as "273gm/m"

1 yard = 0.9144 meters
1 ounce = 28.3495231 grams
273 g/m = 8,8 oz/yard

I haven't worked through the math above, but does your calculation take into account the width of the goods being described? My understanding is that the standard for which weight is reported differs in width, not just length between x/grams per meter and y/ounces per yard.

We've been through this before, often enough to confuse me thoroughly. I gather that some sellers use different widths for a meter of cloth than they do for a yard, so the conversion can vary by merchant.

In any case, a fresco from Smiths is labeled both 11-12 oz, and 360 grams. So figure that somewhere between 30-33 grams per meter <=> 1 ounce/ yard. From Smiths.

No, the one true answer is that 34 grams = 1 ounce. I think Manton got this from someone at Holland and Sherry, and it is the result of both the conversion from non-metric to metric as well as convention.

I believe the last post is correct or close to it. The actual conversion rate I have seen from an unsubstantiated sourcefor converting grams per meter to ounces per yard is to multiply by .0294935. This is awfully close to the reciprocal of 34, which is .02941176.

I got the former figure from http://www.onlineconversion.com/forum/f ... 913322.htm

Then H&S are getting kind of sloppy on their website, where 11oz converts to 340 g and 22.5oz converts to 700g.

Google has a great units conversion feature. For example, enter the following into the Google search box:

360 grams/meter to oz/yard

(The answer is 8.8 oz/yard.)

It will convert lots of other units, too. For example, if you're an American considering commissioning a new bespoke suit from an English tailor, you may want to know the result of this:

2000 pounds to dollars

We have been through this before. It has something to do with the slevage as I recall.
