What color is your blood. Red, right? Well, actually, yes. So why does it look blue when you see it through your skin? And is everyone's blood always the same color red (spoiler: no)? Do all animals have red blood ('nother spoiler: no!)? And why is red blood red anyway?
One large egg weighs approximately 2 ounces. Each egg is classified  into medium, large, extra large, and jumbo based on their actual  weight.
U.S. sizes are defined by the weight of a dozen eggs. (Not individual eggs. An egg in a carton of Extra Large eggs need not weigh at least 27/12 ounces, but the dozen must weigh at least 27 ounces.) Most recipes that call for eggs usually mean Large eggs. Below is a chart that may be used to convert a number of Large eggs to an approximate equivalent in other sizes.
