How many calories does one kiwi have?

A single kiwi is typically 3.2 ounces with a 2-inch diameter and contains about 42 calories, as reported by CalorieKing. Each kiwi contains an abundance of essential vitamins and minerals, like 215.3 milligrams of potassium, 23.5 milligrams of calcium and 0.8 grams of protein, making it an ideal snack. A single kiwi also contains more vitamin C than an equivalent amount of orange.

When picking a kiwi from the store, place the kiwi between the index finger and the thumb and squeeze gently. A ripe kiwi yields a bit to the pressure. The size of the kiwi will not affect its overall taste and sweetness.
