When forming a burger for the grill, aim for a ¾" to 1" thickness and a 3" to 4" diameter. The burgers will shrink slightly as they cook, so you want the raw patties to skew a little larger than the buns onto which they'll eventually land. so say 3.5 inches
The equatorial circumference of Earth is 24,901 miles (40,075 km). However, from the North Pole to the South Pole, the so-called meridional circumference is smaller, at 24,860 miles (40,008 km).
inches in a mile 63360 so divide 3.5 = 18,102.85714285714 round out 18,102.86 in a mile now times 24,901 = 450,779,245.7142857 roundout is 450,779,245.71 burgers arournd the world so times 32 = 14,424,935,862.72 burgers have been eaten in a year TBB let the math speak
