How many calories are in one onion ring?”
but according to the Ohio Stae University campus nutritional services there onion rings have between 50 and 66 claories: http://food.osu.edu/menus/nutrition_info.asp?item=263 That is 200 claories for 3 large or 4 small onion rings. What is even better is that 63% of those calories are from fat. That means ~32 to 43 claories from fat per ring. Here’s a few other sites for different values: http://www.campusdish.com/en-US/CSSE/Virginia/rda.aspx?RCN=10471&MI=120&RN=ONION%20RINGS http://www.calorieking.com/foods/food.php?category_id=21&brand_id=12&food_id=75587&partner= http://www.answers.com/topic/onion-rings They are all around 50 claories.
