The normal pooping pattern of an adult spans from three times a day to once every three days, meaning the average person poops approximately once a day—about 1 ounce of stool for each 12 pounds of her or his body weight. That means a person weighing 160 pounds produces an average of just under a pound of poop each day.
How much does a cup of urine weigh?
It’s amazing how much water weighs! A gallon of water weighs 8 pounds, and a pint of water (16 ounces) weighs 1 pound (in metric, 1 liter of water weighs 1 kilogram). This means that if you drink a 1-litre bottle of soda, you instantly gain 1 kilogram (2.2 pounds) from the water!”
