Bluebulb Projects' The Measure of Things presents:
50,000 is about one-and-two-fifths times the number of McDonald's Locations in the World.
In other words, the count of McDonald's Locations in the World is 0.710 times that amount.
(2015 figures) (approximate)
Operating in 119 countries, there are currently 36,000 McDonald's locations worldwide. From 1955 thru 1993, many McDonald's locations advertised the number in billions of hamburgers sold on their external signs, but abandoned theses updates after the figure passed 100 billion.
