i was hoping someone could give me a-round-about guess of how much 25
or 28 grams of thread would be in length measurments.
It will vary, depending on the thickness of thread - the ticker the
thread, the less of it will fit in the 25 grams. Lacis used to have the
formula in their catalogue for converting weight to length, but it's
been years since I ordered from them, and I don't have any of their old
catalogues anymore.
Anyone can help here?
america sizes their lengths in feet and yards and metric is in meters
and what ever
else there is to measure distance. i'm not very good at the metric
system, although there is a formula to convert on to the other.
The formulae (I learnt them the other way around in school, since
Poland uses the metric system for length, weight and volume, with
Celsius for temperature) are fiddly, espoecially if one is as
mathematically-challenged as I am. But there are shortcuts (what we
used to call "pi times the door" measurements <g>). So, all you have to
remember is:
A yard is "somewhat shorter" than a meter. 3 feet to a yard, each foot
30cm, so 90 cm to a yard, but 100 to a meter.

a thick one, you won't get much. If it is a finer thread, you'll get a
lot more. I have at hand right now a spool of Madeira Tanne 50, a 25
g. spool. It doesn't give the 'mileage' but I guess there are at least
several hundred yards, enough for quite a bit of lace.
And I happen to have kept the 10yrs old Madeira catalogue :) Which
don't, alas, have the formula, but does have the translation... :)
A 25 gram spool of Madeira Tanne cotton 50/2 (39 wraps per centimeter,
according to Brenda's book) is 1265 yards
A 25 gram spool of Madeira Tanne cotton 30/2 (thicker thread, and fewer
- 29 wraps) is 714 yards.
I leave the rest in the hands of more nimble mathematicians <g>
