How Many Calories Are in an Orange? Small, Medium, 100g & 1 Cup — Orange vs Mandarin Guide
If you have ever searched how many calories are in an orange, you have probably seen several different answers. That is normal because an orange is not a standardized package. A small orange may weigh under 100 grams of edible fruit, a medium orange around 130 grams, and a large orange can be much heavier. The best way to understand orange calories is therefore to look at several portions: one small fruit, one medium fruit, 100 grams, and one cup of sections. Raw oranges are relatively low in calories because they contain a large amount of water and only a small amount of fat or protein. A common reference value is about 47 calories per 100 grams. The fruit also provides vitamin C, fiber, potassium, folate, and naturally occurring sugars. Whole oranges are different from orange juice because the intact fruit includes more fiber and usually takes longer to eat. This guide is designed around the search intent behind calorie questions. It gives a portion-by-portion calorie guide, a full nutrition overview, and a direct orange-versus-mandarin comparison. It also explains orange juice calories, differences between common orange varieties, natural sugar, fiber, and practical serving ideas. The goal is to make the numbers useful without pretending that every orange has exactly the same nutritional composition.
