Question: how many calories in a 1 4 cup of unpopped popcorn?
Answer: According to the USDA, there are approximately 240 calories in a quarter-cup of unpopped microwave popcorn. The USDA does not provide nutritional information on popped popcorn, so these are the calories in unpopped kernels. The calorie count will vary once the popcorn is popped and any oils or salts are added.
