I don't know calories and BTU, but I know cubic inches and gallon (231), and millimeter to inch (25.4, exact), ft-lb/minute to horsepower (33,000), and probably a few others.

-- The folks at parties might know that one pound of fat equals about 3,500 Calories! --

I like to amaze my friends with the question about which has more energy, a pound of chocolate chip cookies, or a pound of dynamite?

Some model rocket fans have used a summer sausage with a hole drilled lengthwise as fuel and nitrous oxide as the oxidizer.

It makes a passable rocket motor.
