Japanese sinker numbers to ounces or grams?

[Jer]

I bought a couple 12' Shimano telescopic rods and I want to confirm their casting weights. From what I understood one of them casts 6-15 sinkers and the other 10-20 sinkers. A tackle store site says the 6-15 rod would be 3/4-2oz and 10-20 would be 1.3-2.6 oz

Rod models:

Shimano Holiday Spin HG 15-360
Shimano Holiday Spin HG 20-360

Thank you!

Jer. those weights you got from the tackle site are probably close..usually the REAL casting weight is alot lighter than the rod rating..try 2oz and report how it worked..

I bought some "striped bass" lures/plugs and most are 1.5oz

I wanted to cast them with the 12' rods for snook (?) from the surf or jetty.
If the casting weights I got from the US tackle shop are correct I can play with the lures without worrying about breaking my nice rods.

I also have in mind some very light surf fishing casting sinkers around 1oz. I saw it in a local TV show and the fisherman was using the Shimano Holiday Spin rods or a similar one (Shimano Surf Leader).
