Most recipes list tomatoes by weight or by cups, but rarely both. This guide makes it easy to switch between them. Use the converter below for any amount, or read the charts and examples that follow.
How Many Cups Is a Pound of Tomatoes?
One pound of raw, chopped tomatoes fills about 2.5 cups. Sliced tomatoes pack a little tighter, so you get closer to 2 cups. When you cook tomatoes, they lose water and shrink, so a pound turns into about 1.5 cups of sauce.
| Form of tomato | Cups per pound |
|---|---|
| Raw, chopped or diced | about 2.5 cups |
| Raw, sliced | about 2 cups |
| Raw, pureed | about 2 cups |
| Cooked into sauce | about 1.5 cups |
| Cooked into paste | about 0.3 cup |

Cups per Pound by Tomato Type
Tomatoes do not all pack the same way. Small tomatoes leave gaps, and juicy tomatoes hold more water. Here is what one pound looks like for the most common types.
| Tomato type | Cups (chopped) per pound |
|---|---|
| Cherry or grape (left whole) | about 3 cups |
| Roma or plum | about 2.5 cups |
| Medium globe | about 2.5 cups |
| Large beefsteak | about 2.25 cups |
Beefsteak tomatoes hold the most water, so they cook down the most. Roma and plum tomatoes are meatier, so they give you more usable fruit in each cup. That is why many cooks pick Roma tomatoes for sauce.
How to Measure a Pound of Tomatoes Without a Scale
No kitchen scale? You can still get close using count or cups.
- By count: about 3 medium tomatoes make a pound. About 5 to 6 Roma tomatoes make a pound. About 2 large tomatoes make a pound.
- By cups: about 2.5 cups of chopped tomatoes equals a pound.
- By can: a 28 ounce can holds close to 2 pounds of tomatoes.
These are close estimates. For canning or baking, a scale is more exact. For everyday cooking, the counts above work well.
Real Recipe Examples
Here is how the math works in common kitchen situations.
- Your recipe needs 2 cups of chopped tomatoes. That is about 0.8 pound, or 2 to 3 medium tomatoes.
- Your recipe calls for 1 pound of sliced tomatoes. That fills about 2 cups.
- You picked 5 pounds of tomatoes from the garden. That is about 12.5 cups chopped, or close to 7 to 8 cups of sauce after cooking.
Why the Amount Changes
Three things change how many cups you get from a pound.
- Variety: juicy slicing tomatoes give fewer firm cups than meaty paste tomatoes.
- Ripeness: very ripe tomatoes are softer and pack down more.
- Cut size: a loose cup of large chunks weighs less than a packed cup of small dice.
Because of this, treat every number here as a close guide, not an exact rule.

Metric Conversions for Tomatoes
Cooking from a metric recipe? Here are the same amounts in grams and milliliters so nothing gets lost in translation.
| Amount | Metric equivalent |
|---|---|
| 1 pound fresh | about 454 grams |
| 1 cup chopped | about 180 grams |
| 2.5 cups chopped | about 454 grams (1 pound) |
| 1 cup tomato sauce | about 245 grams |
One US cup holds about 240 milliliters. So 2.5 cups of chopped tomatoes is close to 600 milliliters by volume.
How Many Cups Are in a Can of Tomatoes
Canned tomatoes come pre-measured, which makes them simple to swap for cups. The numbers below include the juice in the can.
| Can size | About how many cups |
|---|---|
| 14.5 ounce can | about 1.5 cups |
| 28 ounce can | about 3 cups |
| Tomato paste, 6 ounce can | about 0.7 cup |
Use the full can with its juice unless your recipe tells you to drain it first. Draining a 28 ounce can leaves you with about 2 cups of solid tomatoes.
How Many Tomatoes You Need for Common Recipes
These rough amounts help you shop or pick the right number of tomatoes from the garden.
- Fresh salsa for 4 people: about 1 pound, which is 2.5 cups chopped.
- A pot of tomato soup for 4: about 2 pounds, or 5 cups chopped.
- A tray of roasted tomatoes: about 2 pounds, which shrinks to roughly 2 cups after roasting.
- Pasta sauce for 4: about 2 to 2.5 pounds of fresh tomatoes, simmered down.
When in doubt, buy a little extra. Tomatoes shrink as they cook, and ripe fruit is easy to use up.
Tips for Measuring Tomatoes Accurately
A few small habits keep your cup measurements consistent from one batch to the next.
- Cut the tomatoes to a similar size so they pack evenly in the cup.
- Pack the cup lightly. Pressing the pieces down adds weight and throws off the amount.
- Save the juice. It counts toward the cup and adds flavor to sauces and soups.
- For canning, weigh the tomatoes instead of using cups. A scale gives the most exact result.
These small steps keep your sauce, soup, or salsa tasting the way you planned.
