Monster energy drink?!
Answers: how does a 16oz of monster compare to a cup of coffee?
An 8 oz cup of coffee has anywhere from 60-100mgs of caffeine depending on the type of bean and the roast.
A 16 oz can of monster contains 160mgs of caffeine.
If you figure that the average for a cup of coffee is 80mg (that would be halfway between the 60-100mgs mentioned) and compare that to an 8 oz serving of monser (80 mgs in half a can) then you'll see that they're actually about the same amount of caffeine per ounce.
