This is in accordance to the number of calories each gram of macronutrient has. 1 gram of carbohydrates contains 4 calories; 1 gram of protein contains 4 calories; and 1 gram of fat contains 9 calories; (nice to know: 1 gram of alcohol contains 7 calories). In this case, the sandwich contains 460 wherein there is 6 grams of saturated fat. This 6 grams of saturated fat is equal to 54 calories. Converting that into percentage: (54 calories of fat)/(460 total calories) x 100 = 11.74% or roughly 12% of calories are from saturated fat.
