Yeeeessshhhh !!! need help with foriegn measures
 

50cm = ?
25cm = ?
15cm = ?
12cm = ?
5cm = ?

25mm = ?
6mm = ?

Are you trying to convert to inches or something else in metric? If you have a pc google conversions for metrics and you should get all you need. here's one of my favorites:

http://www.worldwidemetric.com/measurements.html

What pattern are you using?
Even here in Australia (we are metric) the majority of our pattern only have the fabrics quantities in metric (eg instead of 1/2 yard it would say 50 cm or 1/2 metre) but our cutting plan is usually in inches. You could say that we have to be a bit bilingual here LOL

working with a brain injury here.
think I got the gist of what to do on that site.
not sure I understand the (mm) part.
6mm = 0.23622"...............don;t understand in my head what it is saying.

25cm = 9.84252" am assuming this is just over 9"

it is to make a baby travel change pad quilted.
have to understand first.

50cm = 19 and 5/8"
25cm =about 9 and 7/8"
15cm = about 5 and 7/8"
12cm = 4 and 3/4 inches
5cm = just a whisker under 2"

25mm = 1"
6mm = pretty close to 1/4"

I hope this helps a bit, are you able to get rulers from your stationery store that has centimetres and milimetres? Then you could just put it on your inch ruler and convert them that way.

thanks woody...that makes much better sense.
will look for the ruler on ebay right now.
hugs ...you rock !!

Maybe we need to have a metric measuring tape swap for those in the USA.

Most measuring tapes in Canada have both metric and imperial measurements as do school rulers.

Quilting rulers are all in inches here.

I feel your pain. As part of Europe we switched to metric, although I was taught in Imperial. All weights and measures are sold by the kilo and metre.
Luckily most quilt patterns are in inches (although we have to buy our fabric by the metre :D)

2.5 cm and 25mm are the same length - 1".
cm or centimetre is 1/10th of a metre. mm is millimetre, a thousandth of a metre.
A metre is 39" long.

Virtually all our tape measures are two-sided. All I do is flip mine over. If you need me to send you one, pm me.

Maybe this will help with the thinking process:

If one compared a meter to a ten dollar bill (Think ONE THOUSAND PENNIES)

One meter (39.37 inches) = 1000 pennies
One centimeter = 10 pennies (1/100 of the meter - think perCENT or CENTS in a dollar)
One millimeter = 1 penny (1/1000 of a meter - or 1/10 of a centimeter)

The simpler way of doing it is to just get a ruler, measuring stick, or tape measure with both units on it and measure using the guide.

The approximate equivalents are:

One meter - one yard plus 3-1/2 inches

One centimeter - a couple of threads more than 3/8 of an inch

6 millimeters - about 1/4 inch

2/3 of a centimeter - about 1/4 inch

Dreamer, You can check your measuring tape...the other side should be metric.

I taped an old measuring tape onto my ruler so I didn't have to switch back and forth. Worked just fine for the project.

now you've been told already what the measurements mean.
But with us here in the netherlands ofcourse it's the other way around.
Because it's almost impossible to do the math and get it 100% right I think indeed the best advise is to get a metric ruler.
I'm working with inch-rulers all the time when I'm quilting

Yes, 25 cm is just over 9 inches... I'm a retired science teacher and the "metric" system works so well for science... all units are based on 10s... much easier to convert from one unit to another... but not much easier when trying to convert from one measuring system to another... 1 mm (millimeter) is only 1/10th of a centimeter... very small unit... well, look at the width of a pencil lead.. If you have mechanical pencils they are often .7 mm wide! And that's only .7 of a mm!! so 1mm is a very small distance. It takes 10 mm to make 1 cm (centimeter). One inch is 2.5 cm.. Now I know this is confusing, so the best thing is to use one of the conversion sites. Just be sure you are going from metric (cm) to the more familiar (inches)... Good luck!!

Are you aware that most straight quilting rulers (most rulers period) have centermeters on one side. Just use that side and not the inch side.

No need to go to stationary store--------------USE YOUR OWN rulers that you already have. The straight rulers have metric measures on one side, inches on the other.

If the measurements are given in metric------------USE METRIC. It's on the ruler you have. No need at all to convert. What's more, web site or not, it's way too easy for any of us to mess up conversions.

Probably no one here cares, but a meter is 39.37 inches.

Look at the ruler on your quilting table first. I'll bet you have centimeters.

GrannieAnnie, none of my quilting rulers have metric. That would be very confusing, since there's enough markings on them already. Where are you finding ones that do? (Not that I need or want them, just wondering.)

2.5cm equals 1"

The ruler I used just this morning--------my favorite.
OLFA

I'm so used to seeing both on measuring instruments that I don't even pay attention most of the time.

That's strange. I've seen centimeters marked on yardsticks frequently, but not on quilting rulers. My Olfa mats don't have metric. None of the Olfa products I can find online have both inches and centimeters. They do have a mat that has metric on one side and inches on the other, and they have rulers that are metric only. Did you buy your Olfa rulers in another country?

I use a unit converter to get inches or yards, and round to nearest measure that makes sense.

Okay, I'm confused! Why do you need to convert from one to the other to start with? Use the ruler that matches the pattern! Either inches/feet/yards or metric. Why take a chance to screwing up a conversion.
