How much oil is in a barrel?

Well, did you ever wonder how much oil is in a barrel? You know the news is tell us daily how much a barrel of oil costs. As I type this, oil is down $2.54 a barrel to $122.19. (This did wonders for the stock market today it's up 264 points. But that's another story.)

I grew up in the coal business and we always had 55 gallon drums of oil around. So, I assumed a barrel of oil was 55 gallons. NOT. I came to find out that a barrel of is 42 gallons.

We'll the question that follows that is how many gallons of gasoline come from one barrel of oil? The answer is roughly 20 gallons.

So, now you know and you can impress your friends with this new found information.
