I hope this conversion chart might be something that will help someone like it did for me.

Im sorry that I didnt do more research but it seems this chart I linked to below is inaccurate. It worked for what I needed but still its not as accurate as the other two charts listed above.
Again sorry for any inconvenience.

Do your own search if you like and find the conversion chart that best suits you.
Type in search, standard metric wrench conversion
Thanks

Thank You for the chart. I'll use it for sure

Thank You for the chart. I'll use it for sure

You are welcome.
This is nothing compared to the excellent quality of help Ive received from this site.

Took me an hour to figure out how to print it, but I did and its going in the lid of the book chest,, Thanks

There are errors in the conversions, and omissions.

3/8 and 10mm are not interchangeable. Not at all.

And 27mm is omitted, which is a pretty common size among Kubota equipment. 17mm is also omitted; also VERY common size in most Japanese equipment.

I can tell you which wrenches interchange between SAE and metric systems, at least up to 30mm. This learned from experience and not from any charts. 3/8 and 10 are not interchangeable. 12mm and 15mm don't interchange with any SAE wrenches; neither does 18mm. Those are fairly common sizes. If one was buying a set of wrenches and/or sockets, USUALLY you can just get 1/4, 8mm, 9mm, 3/8, 10mm, 7/16, 13mm, 9/16, 15mm, 5/8, 17mm, 18mm, 3/4, 21mm, 22mm, 24mm, 1", 27mm, 1 1/8", and 30mm. Also keep in mind that some of the "interchangeable" sizes are looser or tighter than what they're supposed to be, like 9/16 and 14mm...the 14 is a little tighter fitting than a 9/16 is on a 9/16 hex bolt. This can come in handy if you have one that's nearly rounded over-sometimes a metric might fit a little tighter and allow you to bust them loose without rounding any further.

I have a Craftsman set at home and many of the wrenches fit tighter than my Matco wrenches I have at work. Thus, a Craftsman 14 won't fit on a 9/16" head, but my Matco stuff will interchange. Weird.

Most newer Kubota lawn and garden equipment uses 30mm socket. It doesn't interchange all that well with a 1 3/16 but as long as both are 6 point, either will work in a pinch.

Just some of my random thoughts on that subject, FWIW.

I hope that works out good for you.

Thanks for your time and corrections.
I might need to see if I can find a different or maybe better and more accurate conversion chart.

 

[Mudball]

Im thinking that you are right lugbolt.
This might be more accurate...

Missing is the all important 12mm, and I suppose for you imperial guys, 1/2".
There are a few different metric standards, thread size to head size, Japanese is different to German, so when I go down to the German Aldi store when they have a special on ratchet ring/open enders, I find that they don't have the sizes I want for Japanese bolts.
So the set they have is 8,10,13,15 & 17, where I want 8, 10, 12, 14,& 17. The most used spanners in Jap range are 10, 12, 14, 17.

For Japanese bolts, grab yourself some correct size metric spanners and sockets, they'll never go astray.

I agree, that for the price of a good metric socket and wrench set, it does not make sense to do any "conversion". Just buy the right tools for the right job, problem solved.

No worries, the new one will do well, and truth be told when you have a box full of SAE stuff,, spending money on more METRIC stuff that aint used all that often, is well a bit over the top, but if you need something the chart will help
