calories in a gallon of
Most of us know how many food calories an adult needs per day, so in the debate over making ethanol from corn to replace gasoline, wouldn't it be nice to know how many food calories there are in a gallon of gasoline? Can you skip breakfast and drive to work on the energy you didn't eat?
The answer is: the number of food calories in a gallon of gasoline is 31,500
For most adults this is the energy in about two weeks of food.
YOU can calculate this. How to calculate page.
