Everybody knows that McDonald’s sells a lot of hamburgers. Figuring out just how many hamburgers they sell not by the day or even the hour, but by the second, seems like a near impossible exercise that only the most math-inclined of burger nerds would take on. Somebody did figure it out though, and in 2013 the fast-food giant was reportedly moving around 75 burgers every second. This burger data roughly breaks down as 4,500 burgers every minute, 270,000 every hour, 6.48 million every day, and 2.36 billion burgers every year.

Other estimates have put McDonald’s burger sales at 50 million a day — worldwide at least. In 2018, McDonald’ had around 13,900 U.S. locations, which was a drop from its peak at 14,350 restaurants in 2014. So while it’s possible they may not be selling quite as many burgers a second as they were a few years go, it’s fair to say they’re still moving a lot of beef patties.

Should you feel like actually watching those burger sales climb, there’s a website dedicated solely to “every second” of McDonald’s sales. Why? Because the internet, that’s why.
