There's nothing mysterious about the world's two most famous burgers. But in honor of National Cheeseburger Day, we're taking a closer look at what sets
Burger King's Whopper, invented in 1957, is a quarter-pound flame-broiled burger plus fixings.
McDonald's Big Mac, invented in 1967, is two 1.1-ounce patties separated by a third bun, plus cheese, fixings, and a special sauce that tastes like mayonnaise plus ketchup. The Big Mac also uses dehydrated onions instead of fresh.
If McDonald's patrons want that extra meat, they can order a Quarter Pounder, which is basically a Whopper made on a standard grill.
The Big Mac has 550 calories and 29 grams of fat while the Whopper has 630 calories and 35 grams of fat.
Since there's no such thing as a blind taste tests between the two signature burgers, it's hard to say which the people like most. In 2008, Burger King set out to find "Whopper Virgins" in remote locations to compare the two burgers. Burger King claimed victory in this taste test but mainly just generated a ton of controversy for being "insulting and exploitative."

McDonald's has 34,000 locations worldwide compared to 12,000 for Burger King.
Earlier this year McDonald's was ranked the fourth most valuable brand in the world by Millward Brown, while Burger King didn't make the top 100.
