Size of # 10 cans

[dburgess49ers]

I am working on a program for measurement conversions. I work in a kitchen so I want to include cans for larger recipes. So I looked to see how many ounces are in a # 10 can. Some cans listed ounces and some weights. I looked online and came up with some sites:
http://www.onlineconversion.com/cooking.htm
http://www.amescompany.com/CAN_SIZES.htm
http://web.singnet.com.sg/~dan123/cansizes.htm
and ofcourse this site.
Now I have asked other chefs if onlineconversions.com is correct in stating that a # 10 can is equal to 1 gallon. Some say 'yes' and some say 'no'. So I did a test and it does not equal 1 gallon. So my question is this:
Are all # 10 cans in the US really a UK can?

The reference books that I own all say 6# 10oz on average. It does not always equal 1 gallon, given that volume and weight do not often make life easy by remaining constant.

...furthermore, one other reference insists 110oz (measure, not weight)... don't mean to complicate things more, but there you have it.

I sent an email to Dantraco Associates and they replied:
The can number "10" was originated from U.K.
It's a standard that comply with it's actual "can size" developed by "Metal Box - U.K." ( Canmaker ) in the early '50. Since then there are still many Canmakers and Packers / Fillers using it's number.

Depending on it's content, the volume / weight maybe difference.

Basically, the numbers use are for "Can Sizes" mesurement only.

So I guess I will need to offer different volume amounts for # 10 cans depending on the size of the can; ie. 603x700/153x176 @ 108 oz or 603x830/153x181 @ 128 oz.
Now, was that liquid or dry :smirk:
