Energy The abil ity to do work (make something happen) Joule (J)

Calorie (cal)

The calories on food packages are really kcal

Electron Volt (eV)

British Thermal Unit (btu)

Kilo watt hours (kWh)

Your body gets 8000 J (1 900 cal = 1 9 kcal) of energy from eating a peanut

6O J of energy are need per second to keep a 60 W appliance running

1 gallon of gas produces 1 32times108 J of energy or enough energy to keep a 60 W appliance running for 25 days
