put it on the scale and you will have the anwer.
For a medium onion, figure about a half cup.
Small onion = 4 ounces by weight or about ½ cup chopped Medium onion = 8 ounces, or about 1 cup chopped Large onion = 12 ounces, or about 1½ cups chopped Jumbo onion = 16 ounces, or about 2 cups chopped
Have you ever noticed how onions can be many sizes ? 1 chopped onion could be 0.5 cup to about 1.5 cup
About 8.5 ounces (240 grams)
A tablespoon of onion powder equals about a medium sized onion, which would be about a cup, chopped. So, a tablespoon.
1 small equals 1/4 cup chopped 1 medium equals 1/2 cup chopped 1 large equals 1 cup chopped Hope this helps! Found this answer at http://home.answerbox.net/garden-search-onion%0A%0A1-396545368.htm
I just weighed one cup of chopped onion: 4 ounces.
Equivalents: 5 medium onions = 1 pound = 2 cups chopped = 3 cups sliced1 small onion = 1/3 cup = 1 teaspoon onion powder = 1 tablespoon dried onion flakes
About 120 grams of dried onion.
The web references vary and show medium onions as 3/4 to 1 cup chopped and large onions as 1 to 1.5 cups chopped.
About half of a cup (slightly more, depending on what you call "small"). -Rachel
2 2/3 cups equals 2.8 ounces. IF you are trying to make the green bean casserole and it tells you to add i/2 cup of onion rings, add 1 1/3 cups and then top with 1 adn 1/3 cups,Eleanor
