I have been looking for some type of chart or information to help me compare tenkara hook sizes and how they compare to US hook sizes. I have looked around on the web but cannot find enough information to really be of any help. I would greatly appreciate if anyone would share this information. Thank you ahead of time for your help and efforts. 
I think Todoroki-san or Keiichi Okushi could help us.
Somewhere I have a chart for tippet conversion.
I stop trying a while ago, trying to convert Japanese sizes to Imperial or American, whatever.
As an example…
I just use meters, my rod is 3.9m fully extended, I use premium .8 fluorocarbon tippet, #3.5 - 4 pink fluorocarbon premium line and a certain Owner “Super Yamame” 7 - 7.5 keiryu hook. Oh, I like a 6:4 medium tone rod or there about.
It’s funny, some people ask me to convert and I just have to guess and look stupid.
I don’t care.
I should.

Thank you Adam.
I wish I could help.
But now it’s a thing for me.
I am sort of stubborn with some things.

I’m not sure why, but it drives me a little crazy when the hook packs from Japan list sizes like 3, 5, 6, and 7.
How does this compare to the Western hook units such as #10, #12, and #14? I’m sure there must be other tenkara anglers with the same question unless I’m the only idiot on the dunce stool.

There is no universal standard

5号・・・＃14
6号・・・＃13
7号・・・＃12
7.5号・・＃11
8号・・・＃10
9号・・・＃9
10号・・・＃8
・・・”Kitune-gata” one step size up

Todoroki-san,
Thank you very much for your help. I looked around on the internet but could only get some information but not enough. This now solves the question I asked and gives Adam T. the information as well. Thank you once again.

Adam I’m the same way with rod lengths. “uhh, it’s a 4.5m rod, I’m not sure how many feet that is lol”
Yup, a guy asked me today, “Is that a 12’ tenkara rod?”
Yep!
