The Quarter Pounder is a hamburger sold by international fast food chain McDonald's. Along with the Big Mac, it is one of the company's signature products. The burger comprises a beef patty weighing 4 oz.
(113.4 g.) before cooking and 3 oz. prepared, pickled cucumber, raw onion, ketchup, and mustard. The more common variant, the Quarter Pounder with cheese, adds two slices of American cheese.
In most markets unfamiliar with imperial measurements, the Quarter Pounder is known as the Hamburger Royale or McRoyal, or variants thereof, including "Royale with Cheese", as famously explained in the film Pulp Fiction (although one should note that in France the official name of the Quarter Pounder with Cheese is Royal Cheese). In some countries that have adopted metrication, such as Canada and Australia, the burger retains the Quarter Pounder name. Quarteirão com Queijo is used in metric Brazil, Cuarto de Libra con Queso in Latin America, Quarter Pounder is used in Finland and QP Cheese in Sweden In South Africa there are 2 variations, the Quarter Pounder with cheese and the Quarter Pounder Deluxe.
In some Middle-Eastern countries such as Saudi Arabia and United Arab Emirates, McDonald's provides both a Quarter Pounder and a McRoyale burger on its menu, the McRoyale having slightly different ingredients.
