ok... and?
Other than posting on here and expecting someone to solve it for you, what have you done to try and determine it?

What do you think you need to convert, other than 12" = 1'?
Correct me if I'm wrong, but steam drums usually have a level of liquid that they maintain with the balance of the volume being vapor. Volume of a cylinder is pretty simple, so the rest should be simple physics. Clearly this is not what you are trying to do, so what am I missing?
Sounds like you need a thermo book more than a conversion chart.

No, what you need is pretty simple arithmetic and a lot more data. Do you want to know how much steam a closed vessel will hold at 150 psig? Depends on how much liquid is still in it when you reach 150 psig.
By "capacity" do you mean how much steam can be generated in a system with a water supply and heat source? If so you need to specify the heating capacity of your heat source.
Asking for a "conversion chart" begs the question "why are you here?". If you don't even know enough to know that the question you asked cannot be answered with a "conversion chart" then the next step in your learning curve could easily be a Darwin Award. This stuff can be really dangerous if you don't know what you're doing.

Well on ave. asking for a chart was incorrect, sorry. 37.5Mbtu @ 35Mpph/hr steam, H2O level is @ 18" so yes after refering to the old Theromo book I have firgured it out. I am a controls Eng. not mechanical so I wsa looking for a direction. Not a smart ass comment, but thank you!
Sorry, but a smart-ass comment got you off yours and got you to open a book. Seems like a smart-ass comment was exactly what you needed.
If you are going to be around here much, you need to realize that everyone here is unpaid and here for their own reasons. The best way to get some AMAZING answers is to ask INTERESTING questions and by providing any follow-up information that is requested. The best way to get laughed at and sniped at is to demonstrate that you haven't done enough pre-work to be able to understand a sarcastic answer.

bpk,
The answers you get on this site are a direct reflection of what you, as the original poster, ask. No one here is a mind reader, and when the answer seems really obvious, and the original query is lacking any information to support it being work-related, I, at least, assume that the poster is a lazy high school or college student. Unfortunately, way too many times, my assumption's accurate, even if this time it wasn't.
I'm very glad you found the old thermo book, figured the answer out and took the time to come back and share your answer, especially as you evidently realized that even if someone was inclined to answer, you didn't give him/her all the needed information ("37.5Mbtu @ 35Mpph/hr steam") originally.

If you meant steam separation capacity, then one needs to know what sort of separators are installed in the drum. The latest trend for LP drums is away from centrifugal separators and demisters and toward stainless steel lathe . The vendor of the steam separators will publish charts of steam seperation capacity.
