Tomato Conversions & Equivalents

Tomato Conversions & Equivalents

I seem to have a lot of trouble remembering how to convert some ingredients. How many cups of dry beans convert to how many ounces of cooked beans is always hard for me to remember. The same is true with tomatoes.

I needed to know how many ounces of fresh tomatoes are there in a 32 ounce of canned tomatoes. The reason you need to know these conversions is because some recipes give you the tomatoes fresh, some canned, some as tomato paste.

You may not be able to get your hands on some fresh tomatoes out of season so you resort to canned. Doesn’t matter, here are tomato conversions that may be useful to you when cooking.

Of course all this varies depending on the type of tomato you are referring to, but this will give you a good ballpark figure.


Tomato Conversions

1 small tomato = 3 – 4 ounces
1 medium tomato = 5 – 6 ounces
1 large tomato = 7 ounces
1 cherry tomato = 1/2 – 2 ounces
3 medium round tomatoes = 1 pound
8 plumb tomatoes = 1 pound
15 – 20 cherry tomatoes = 1 pound
25 to 30 cherry tomatoes yields 2 cups chopped
1 pound fresh tomatoes yields 1-1/2 cups chopped
1 pound fresh tomatoes yields 3 cups pureed
2-1/2 pounds fresh tomatoes yields 3 cups chopped, drained
2-1/2 pounds fresh tomatoes yields 2-1/2 cups seeded, chopped cooked
2 cups chopped tomatoes = 1 pound
1 (14-1/2 ounce) can tomatoes = 5 to 6 whole or about 1 pound
1 (16 ounce) can tomatoes = 2 cups
1 (28 ounce) can tomatoes = 3 cups
1 (28 ounce) can tomatoes = 10 to 12 whole or about 2 pounds
1 (35 ounce) can tomatoes = 4 cups

Tomato Paste Conversions

3/8 cup tomato paste + 1/2 cup water = 1 cup tomato sauce
1 (6 ounce) can tomato paste yields 3/4 cup

    I am wondering, if I dehydrate 8 medium tomatoes, how much tomato powder should I expect?

    I use one 6 oz Tomato Paste to 1 cup water for 14 oz of Tomato Sauce.

    I grow my own tomatoes and roast them off when I have enough ripe ones. My question is what is the ratio of roasted tomatoes to fresh chopped tomatoes?

    • Hi Cassie, great question and one I had to research a little. I found a recipe from Mark Bittman for roasted tomatoes that calls for 24 fresh plum tomatoes that yields 2 cups of roasted tomatoes. Since there are about 8 plum tomatoes per pound, that means 24 plum tomatoes equals around 3 pounds of fresh plum tomatoes. So I’m going to say 3 pounds of fresh plum tomatoes chopped should yield about 2 cups roasted. If anyone has a better conversion, please share.

    1 (28 ounces) can tomatoes = 10 to 12 whole or about 2 pounds

    Please explain how 10 to 12 fresh tomatoes is equal to 2 lbs. Most often one tomato is equal to one pound. By your metric, if I substitute fresh for canned 30 lbs of fresh tomatoes is equal to 15 (28 ounces) of canned tomatoes.

    • Hi Rose, thanks for pointing this out. Most canned tomatoes are plum tomatoes which are not nearly as big as steak tomatoes that can be huge and possibly weigh around a pound. Try buying a 28 ounce can of tomatoes and count how many are in there. You may be surprised.

    I was wondering how many tomatoes are used in one container of store bought tomato sauce. This is because I need to know how high the vegetable : junk ratio is… I want to know how much sauce I need to have an accurate supplement for real vegetables.
