I have onions in my pantry going from 1 oz right up to about 12 oz, -Have you never noticed they come in many sizes.
Around 500 grams are in a large brown onion.
About 8.5 ounces (240 grams)
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
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
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.
I do not detect any flavor differences in the two.
Onions can be from about 20 gm up to over 400 gm
About half of a cup (slightly more, depending on what you call "small"). -Rachel
For a medium onion, figure about a half cup.
put it on the scale and you will have the anwer.
