Many recipes will call for "1 cup of chopped green onions" or "1/2 cup of sliced green onions" but it is not always obvious to determine actually how many green onions are in a cup. In order to help make cooking easier we did some experiments to help discover how many green onions you need to buy.
To answer How many green onions in a cup we went to the grocery store to check out the produce section. After surveying the vegetable selection we discovered that 1 bunch of green onions contains about 6 to 8 medium bulbs weighing a total of 3.8 ounces (105g). For our test measurements we used 1 medium green onion with tops that had a total of 4 to 4.25" of useable area; these test models weighed about 1/2 ounce (15 grams) each.
Once we started working in the kitchen, we found that 1 medium green onion gave us about 2 tablespoons of chopped onion weighing about .4 oz (11.3 grams). For a whole cup of chopped green onions, it took about 9 green onions or just a little over 1 bunch of our test-size produce. Depending on how they're priced, you could look for either an extra full bunch or go with 2 smaller bunches to reach a full 1 cup mark. If your going for a finely diced cup of green onions, then you will need to purchase about 1.5 bunches.
Did you know that people often use the term "green onion" to represent either "Spring Onions" or "Green Onions" proper, but they are actually quite different. Spring onions are very young stalks of any onion, which are picked and eaten before fully developing the normal large bulb. On the other hand "proper" green onions will never develop into the large traditional onion bulb no matter how long they remain in the ground. But the good news is there's no practical difference between these 2 onions in the kitchen.
