Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Is there a magic formula for converting lbs of something to water gallons? I do not have to be accurate to the Nth degree, just in the ballpark.

How many water gallons is 600 lbs of R-22 refrigerant?
How many water gallons is 20 lbs of propane (blowtorch tanks)?
Etc. etc.

I need to do this for reporting requirements. The form specifies flammable gas and non-flammable gas amounts in "water gallon capacities" so I need to know how much I have in "water gallon capacity" to find out if I'm required to report it or not.

Thanks for any help

The magic formula is called "density." It is a property of the material, in general is different for each material, and you have to look it up in a reference book. The Handbook of Chemistry and Physics is a good place to look but there are other references.

If you divide mass by density, you get volume. If you multiply volume by density, you get mass.
