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.

water heater capasity

if a water heater is 30'' in diameter and 60'' tall how many gallons will it hold?

Assuming it is a cylinder, its volume = Pi x r² x h
where Pi = 3.142, r = radius & h = height.

If you do it all in inches the answer will be in cubic inches, then use the converter in this site to convert to gallons, but don't forget their are two types of gallons, US and imperial, make sure you use the right one!

I'll leave you to do the arithmetic.
