How many grams of carbohydrates are in a carbohydrate?

Answer 1

A carbohydrate is mass, and "gram" is a unit to measure the weight of mass. So any given mass of carbohydrate will have a weight measurable in grams. For instance, 1 cup of corn weighs 166 grams. Of that weight, 123 grams are carbohydrates. I think your real question may have been, "How many calories in a gram of carbohydrate?" This is a little tricky because indigestible fiber is considered to be carbohydrate but being indigestible has no calories. Non-fiber carbohydrates are considered to have 4 calories per gram. So in the example of the corn, there are 12 grams of fiber. This leaves 111 grams of carbs times 4 calories = 444 calories from carbohydrates. There are 16 grams of protein in the 166 gram quantity and protein is also counted @4 calories per gram, so 4x16= 64 calories from protein. Fat is considered to have 9 calories per gram and the cup of corn contains 8 grams of fat, so 8x9=72 calories from fat.
