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.
The conversion from grams to tablespoons for onions can vary slightly based on whether the onion is chopped, diced, or sliced. However, a general estimate is that 1 tablespoon of chopped onion weighs about 10 grams. Therefore, 400 grams of chopped onion would be approximately 40 tablespoons.
About 8.5 ounces (240 grams)
Around 500 grams are in a large brown onion.
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.
One cup of chopped onions typically weighs around 150 grams. However, this can vary slightly based on the size and type of onion. It's always a good idea to measure for accuracy in recipes.
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.
