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)
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
A tablespoon of onion powder equals about a medium sized onion, which would be about a cup, chopped. So, a tablespoon.
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.
One medium onion typically yields about 1 cup when chopped. To substitute with onion salt, use approximately 1 teaspoon of onion salt for every cup of chopped onion. Keep in mind that onion salt contains salt, so you may want to adjust other salt in your recipe accordingly.
About half of a cup (slightly more, depending on what you call "small"). -Rachel
