Ten average cherry tomatoes (about 170 g) pack roughly 31 calories, based on ~3.1 calories per 17 g tomato.
Cherry tomatoes are tiny, bright, and easy to snack on. When you count them by the handful, it helps to know what that handful means for your daily tally. The short math uses two facts: tomatoes average about 18 kcal per 100 g, and an average cherry tomato weighs close to 17 g. Multiply those and you land near 3.1 kcal each. Ten pieces come out to roughly 31 kcal.
10 Cherry Tomatoes Calories — At A Glance
Here’s the quick view using common sizes you see in stores. A small piece around 12 g lands close to 2 kcal. A hefty one near 25 g lands near 4.5 kcal. Most cherry tomatoes fall between those points, so the ten-count range runs from the mid-20s to the low-40s, with the average near 31 kcal.
| Count | Approx. Weight (g) | Calories (kcal) |
|---|---|---|
| 5 | ~85 | ~15.5 |
| 10 | ~170 | ~31 |
| 12 | ~204 | ~36.5 |
| 15 | ~255 | ~46.5 |
| 20 | ~340 | ~62 |
Estimates use ~17 g per tomato and ~18 kcal per 100 g. If your tomatoes run small or large, adjust the weight column and recalc.
How The Math Works
Food databases list tomatoes at about 18 kcal per 100 g. One cup of cherry tomatoes is 149 g with 27 kcal, which lines up with that 18-per-100 rule. For storage and selection, the USDA SNAP-Ed produce guide is a reference. Those reference points make it easy to estimate any count you happen to have. Here’s the simple formula:
Per 100 Grams And Per Piece
- Per 100 g: ~18 kcal.
- One cherry tomato: weight in grams × 0.18 = kcal. With a 17 g piece, that’s 17 × 0.18 ≈ 3.1 kcal.
- Ten pieces: 10 × 3.1 ≈ 31 kcal.
What If Yours Are Smaller Or Bigger?
Sizes vary by variety and season. A small cherry tomato can be near 12 g; a large one can push 25 g or more. Use the same weight × 0.18 rule. Example paths:
- Small: 12 g × 0.18 ≈ 2.2 kcal. Ten small pieces ≈ 22 kcal.
- Large: 25 g × 0.18 ≈ 4.5 kcal. Ten large pieces ≈ 45 kcal.
- Mixed: Weigh all ten together. Multiply the total grams by 0.18 for one step math.
Calories In Cherry Tomatoes Per 100g And Per Tomato
Most shoppers see tomatoes sold by the cup, by the pint, or as loose pieces. A cup of halves comes in at about 149 g. At the same 18-per-100 rate, that cup lands at ~27 kcal. A pint clamshell can vary, but many land near 280–320 g. That range gives you roughly 50–58 kcal for the whole box. These figures match the idea that cherry, grape, and small plum tomatoes share a low energy density. You get volume, texture, and plenty of flavor for very few calories.
Macro Snapshot For Ten Pieces
Ten pieces bring about 6–7 g carbs, ~2 g fiber, ~4–5 g sugars, and ~1.5 g protein, with very little sodium. Light and fresh.
Vitamins And Minerals Snapshot
Ten pieces supply roughly 20–25 mg vitamin C and about 350–400 mg potassium, plus small amounts of folate and vitamin A. That’s a tidy boost for a ~31 kcal snack. If you rotate colors, the mix of carotenoids shifts a bit, yet the calorie math stays the same.
No Scale? Use Simple Visual Cues
A kitchen scale is the gold standard, yet you can get close with a few visuals. Ten average cherry tomatoes make a loose handful. Halved, they mound into about a heaping cup. If your tomatoes look petite, plan closer to the low end of the calorie range from the first table; if they look chunky, use the high end.
Common Logging Mistakes
People often tap the wrong item in an app and end up far off the mark. “Sun-dried tomatoes in oil” is a very different entry from fresh cherry tomatoes. Another miss is counting pieces after tossing them with oil or dressing, then logging only the tomatoes. Log the add-ons too. If you buy marinated tomatoes at a deli, ask for the nutrition card or weigh a drained portion and estimate the oil separately.
What Changes The Count In Real Life
Water content shifts with ripeness and storage. Tomatoes with more water weigh slightly more for the same size, which nudges the math up a touch. Varieties labeled “grape” can be a bit denser than round cherry types of the same size. The swing is modest at the ten-piece level. Cooking drives off water. Roasted or air-fried pieces shrink and taste sweeter, yet the calorie count per 100 g rises because the grams go down. If you weigh after cooking, your per-100 g label still applies; the serving simply weighs less.
Add-Ons That Move The Needle
Plain tomatoes are lean. Mix-ins change the picture fast. If you track closely, measure dressings and toppings separate from the tomatoes themselves.
- Olive oil: about 40 kcal per teaspoon, 120 per tablespoon.
- Mozzarella pearls: around 70–90 kcal per 28 g (1 oz), depending on the brand.
- Balsamic vinegar: near 14 kcal per tablespoon.
- Avocado: about 50 kcal per 50 g chunk.
- Croutons or toasted crumbs: numbers vary widely; weigh for accuracy.
Cherry Versus Grape Or Roma
Calorie density across small tomatoes is very similar. When you compare per 100 g, the values cluster around the high teens. You might see minor swings between data sets or crops, yet your ten-count bowl lands in the same ballpark. Treat them as near-equals and pick the texture you like.
Easy Ways To Spend 100 Calories
Here are ideas that stay near the 100 kcal mark:
- Ten cherry tomatoes with 30 g light mozzarella and basil.
- Ten cherry tomatoes with 1 teaspoon olive oil, a pinch of salt, and a splash of balsamic.
- Ten cherry tomatoes with a small can of tuna in water and lemon.
Buying And Storing For Consistent Results
Look for firm, glossy skins and bright color. Avoid cracked tops or soft spots. Store at room temperature for better flavor, then chill only if they’re about to over-ripen. Wash just before eating so water doesn’t pool around the stem scar. Treating them gently keeps texture, which means your weighed portions match what you logged last time.
Variety Notes
Round cherry tomatoes, grape tomatoes, and baby plum tomatoes all sit in the same low-calorie tier. Grape types tend to be a touch more oval and denser; round cherry types can be juicier. If you swap styles, your ten-count snack stays in the same ballpark for energy, so flavor can drive the choice.
Why Sources Sometimes Differ
Not every database tests the same batch of tomatoes. Seasons, growing regions, and lab methods vary. One trusted aggregator reports 27 kcal for 1 cup at 149 g, which back-calculates to ~18 kcal per 100 g. You may see higher numbers on sites that round up or that pool different tomato types.
Raw, Roasted, Or Sauced
Fresh cherry tomatoes eaten raw keep all that water inside the fruit, so the calorie count per 100 g stays low. Roast them and they lose water, which concentrates the sugars and bumps the calories per 100 g even though you didn’t add anything. Add oil and the number climbs much faster, since fat is energy-dense. Jarred sauces often include oil and sugar, so read the label and log the brand you used.
Seasoning Ideas With Minimal Calories
Boost flavor without changing the math much. Try flaky salt and pepper, lemon zest, chopped herbs, garlic, or chili flakes. A splash of vinegar perks them up for almost no energy cost. If you crave a creamy note, swap heavy dressings for a spoon of fat-free yogurt or a dusting of grated hard cheese.
Serving Sizes You May See On Labels
Labels and trackers often provide preset measures. The numbers below use the same 18-per-100 rule so you can compare shapes and containers without guessing.
| Portion | Typical Weight (g) | Calories (kcal) |
|---|---|---|
| 1 cherry tomato | ~17 | ~3.1 |
| 10 cherry tomatoes | ~170 | ~31 |
| 1 cup, halves | ~149 | ~27 |
| 1 pint clamshell | ~300 | ~54 |
Simple Ways To Be Precise
Use a small digital scale when accuracy matters. Tare a bowl, zero it, and pour in your tomatoes. Multiply the grams by 0.18 for an instant estimate. If your app or tracker supports custom entries, save “cherry tomato, raw, 100 g = 18 kcal” as a quick item. The next time you snack, you can weigh once and log in seconds. If your scale shows ounces, multiply by 28.35 to convert to grams, or change the unit setting if your model allows it. When you meal prep, jot the weight on the lid so logging takes seconds next time.
Final Take On 10 Cherry Tomatoes
Ten average cherry tomatoes come out to roughly 31 kcal. The exact number shifts with size, but the swing is small for most bowls. If you need a rock-solid figure, weigh the batch and use the 18-per-100 shortcut.
