Use this free tomato measurement converter to switch instantly between pounds, ounces, cups, pints, quarts, whole-tomato counts, cans, and cooked yields. As a quick rule of thumb: 1 pound of fresh tomatoes ≈ 3 medium tomatoes, about 2½ cups chopped, or roughly 1 cup of tomato sauce. Enter your amount below to convert any tomato measurement.

How many tomatoes are in a pound, cup, or can?
A pound of fresh tomatoes is about 3 medium tomatoes, 5–6 Roma (plum) tomatoes, or roughly 38 cherry tomatoes — which works out to about 2½ cups chopped. A standard 28 oz can holds the equivalent of about 10–12 whole plum tomatoes (≈1¾ lb), and a 14.5 oz can is about half that.
Fresh-to-cooked tomato yield
Tomatoes shrink a lot as they cook down. As a guide, 1 pound of fresh tomatoes makes about 1 cup of tomato sauce, roughly ⅓ cup of tomato paste, or about ¾ cup of crushed tomatoes/puree. Paste is the most concentrated, so it takes the most fresh fruit.
Why tomato measurements vary
These conversions are estimates. The exact weight and yield depend on the variety (a juicy beefsteak vs. a meaty Roma), ripeness and water content, and how finely you chop (a loosely chopped cup weighs less than a packed one). Use the converter above for a fast estimate, then adjust to taste.
