Help-Converting Japanese hooks to US sizes

[mrsbrightside]

Hi, I just purchased a set of Japanese hooks Raku Raku Hamanaka and I need help converting their hook sizes to US or even millimeters

 

Sizes are as follows:

 

2/0, 3/0, 4/0, 5/0, 6/0, 7/0, 7.5, 8/0, 9/0, 10/0

 

TIA!

Is this what you got here ?

 

It has info for mm and letter size. Those are cool I might want some.

[mrsbrightside]

Yes but another site says:

7/0 =F

7.5=G

8/0 =H

 

I have found conflicting sizes and the first 5 don't have any conversions contributed to them? I really love them, their cool to crochet with, I was just hoping that someone had more info about Japanese hook sizing than I have.

It gives all the mm sizing so if you look at a US hooks they all include a number and a mm size on them. Then you can see how to translate them for US patterns.

 

I forgot about these links that might help.

If you look at basic us hooks they all have mm sizes on them as well.

This is not the problem I am have. The few Japanese conversion sites that I have http://www.tropicalknitter.com/sizeguide.html , this one where I purchased themhttp://www.etsy.com/view_listing.php?listing_id=6288567, and the one you listed (which I've looked at before)

http://www.geocities.com/nornsneedlework/crochet/hookchart.htm

all have BIG differences with their conversion from Japanese sizes to mm.

 

I am trying to find a consistency among the conversion charts and I'm having a hard time doing this. Is there a way of measuring them yourself?

Would something like this help? http://www.yarnsupply.com/14099.html. It has holes that you can use to determine the size. I got mine at Michael's or Hobby Lobby.

Can't you just compare them to other hooks (of KNOWN sizes) and make an educated guess ? I wouldn't worry about it, unless gauge is really important for your project.....and then if it is,make a swatch to see which hook works best, or just use a G hook if that is what the pattern calls for. Those are cool hooks....but I foresee a problem with them......let's say that your project is now a UFO that has been sitting around for awhile......your project has a hook with it, but that hook has two different sides to it.......which size were YOU useing when you started the project? This happens to me all the time, (and I have conventional hooks..... they somehow always get seperated from my UFOs) So, I suggest that you figure out a way to remember which end you were working with on each pattern! Perhaps write it down in a notebook.

whoa! those are awesome!

yeah, tempestuous kitten is right. i got one of those at michaels for about 2 bucks. they make them in plastic and aluminum. i got the aluminum and i think i should have spent a dollar more to get the plastic one because it bends really easily. they are nice for swatches too. i think its something all crocheters should have. get one of those and measure your hooks and then mark the size with a permanent marker, i think that would be the easiest way to go.

The sizes are as follows in mm, the size in US sizes are going to be in here as well. You'll still have to just give it a try and test your gauge and see if your work is working out for the pattern your working.

 

2/0 - 2.0mm

3/0 - 2.3mm

4/0 - 2.5mm

5/0 - 3.0mm

6/0 - 3.5mm (F)

7/0 - 4.0mm (G)

7.5/0 - 4.5mm

8/0 - 5.0mm (H)

9/0 - 5.5mm (I)

10/0 - 6.0mm (J)

 

BTW...I just found the new RAKU RAKU set for 0-10 for lace crocheting sizes... I have only 2 sets but I'll be getting more soon. They are really kewl, I've been waiting for these sizes to come out so I could get rid of my other hooks...doing my antique booties and lace butterflies were killing me with my Susan Bates hooks...major cramping...now not so much with the new ones. I love it!

BTW, with those size measures, they don't always work. Not all hooks no matter what size it says on the hook will be the same, sometimes the head isn't the same size and it won't fit though the hole even though it is a size G. Those guides are very subjective so I would just go based on your work, that is the only sure fire way to know.

This was discussed in another thread and here is where we finally found the answer: http://www.tulip-japan.co.jp/kyoutsu(englis)/syugei/lace.html
