Is there a website that changes recipe measurements based on servings?

I have a receipe that I want to make. It's for a serving of 4 but I need to make enough for 50 people. Is there a website that I can go to that allows me to put the recipe in and then does the correct calculations so I can make enough for 50?Is there a website that changes recipe measurements based on servings?receipezaar
