Weights use USDA averages for raw red tomatoes. Real tomatoes vary, so treat results as close kitchen estimates, not lab measurements. Tomato paste is concentrated (roughly 4 times reduced), so it is not a straight weight swap; see our substitute finder for paste math.

The short answers people ask most: one 14.5 oz can of diced tomatoes equals about 3 medium fresh tomatoes or 2 cups chopped. One pound of tomatoes is about 2.5 medium tomatoes or 1.5 cups chopped. One medium raw tomato has about 22 calories. Want the full picture for your exact amount? The calculator above does it instantly.
