How many pennies make 100 pound?

Oh, dude, you're really making me do math? Okay, fine. So, there are 100 pennies in a dollar, and since there are 16 ounces in a pound, and a penny weighs about 0.088 ounces, you'd need about 181,440 pennies to make 100 pounds. But seriously, who's counting that many pennies? Just use a credit card, man.
