Celery is a famously low-calorie vegetable, but the exact number of calories in a cup depends on how you prepare it and how you measure it. This calculator helps you estimate the calories in raw celery, cooked celery, and celery juice, based on the amount you actually eat. Whether you're tracking calories for weight loss, meal planning, or just curious about your snack, this tool gives you a quick and accurate estimate.
Simply choose the form of celery, enter the number of cups (or use the quick-fill buttons for common serving sizes), and the calculator will show you the total calories, calories per 100 grams, and a breakdown of macronutrients. You can also adjust for chopped vs. diced pieces, which changes how much celery fits in a cup. This is a handy tool for anyone following a calorie-controlled diet, a low-calorie eating plan, or just trying to eat more vegetables.

How to Use This Tool
Using the celery calorie calculator is straightforward. Start by selecting the form of celery you're eating: raw, cooked (boiled and drained), or celery juice. Then enter the amount in cups, tablespoons, or grams. If you're measuring raw celery, also choose whether it's chopped or diced — this matters because diced pieces pack more tightly into a measuring cup, so a cup of diced celery weighs more and contains more calories than a cup of chopped celery.
For quick entry, use the preset buttons for common serving sizes like ½ cup, 1 cup, 1½ cups, or 2 cups. After clicking Calculate, you'll see the total calories, the equivalent weight in grams, and a macronutrient breakdown (carbs, protein, fat, and fiber). The reset button clears all fields and returns the calculator to its default state.
How It Works
The calculator uses standard USDA nutrition data for celery. Raw celery contains about 16 calories per 100 grams, while cooked celery (boiled, drained) has about 18 calories per 100 grams, and celery juice has about 21 calories per 100 grams. The weight of a cup varies by preparation:
- Raw chopped celery: ~101 grams per cup
- Raw diced celery: ~120 grams per cup
- Cooked celery: ~150 grams per cup
- Celery juice: ~236 grams per cup (8 fluid ounces)
To calculate calories, the tool multiplies the weight in grams by the calories per 100 grams and divides by 100. For example, 1 cup of raw chopped celery (101 g) gives 101 × 16 / 100 = 16.2 kcal. The macronutrient values are also derived from USDA data: raw celery has about 3.0 g carbs, 0.7 g protein, 0.2 g fat, and 1.6 g fiber per 100 g.
Worked Examples
Example 1: You're making a salad and use 1.5 cups of raw chopped celery. The calculator converts 1.5 cups to 151.5 g, then multiplies by 16 cal/100g to get 24.2 kcal. The breakdown shows 4.5 g carbs, 1.1 g protein, 0.3 g fat, and 2.4 g fiber.
Example 2: You drink a glass of celery juice made from 2 cups of celery. Since juice is denser (236 g per cup), 2 cups equals 472 g. At 21 cal/100g, that's 99.1 kcal — significantly more than eating the same volume of raw stalks, because juicing removes fiber and concentrates the liquid.
Example 3: You're tracking a cooked celery side dish and eat 0.75 cup. Cooked celery weighs about 150 g per cup, so 0.75 cup is 112.5 g. At 18 cal/100g, that's 20.3 kcal. Notice that cooking increases the calorie density slightly because water is lost and nutrients become more concentrated.
Tips & Best Practices
- Measure accurately: Use a dry measuring cup for chopped or diced celery, and a liquid measuring cup for juice. Fluff chopped celery lightly rather than packing it down.
- Account for dips and dressings: Celery itself is very low in calories, but adding peanut butter, ranch dressing, or cream cheese can add 50–100+ calories per serving. Track those separately.
- Use the gram option for precision: If you have a kitchen scale, weighing celery in grams is the most accurate method. The calculator accepts grams directly.
- Remember fiber: Celery is a good source of dietary fiber, which aids digestion and helps you feel full. The fiber content is included in the breakdown.
Factors Affecting Accuracy
Calorie counts are estimates based on average USDA values. Actual values can vary due to growing conditions, variety, and how the celery is prepared. For example, celery that is very fresh and crisp may have slightly higher water content, lowering its calorie density. Cooking methods also matter: boiling leaches some nutrients into the water, while steaming retains more. If you're following a strict diet, use the gram-based measurement and refer to the nutrition label on packaged celery products.
Frequently Asked Questions
Is celery a negative-calorie food? No. While celery is very low in calories, the energy your body uses to digest it is less than the calories it provides. The idea of "negative calories" is a myth, but celery is an excellent choice for low-calorie snacking.
How many calories are in a celery stalk? A medium stalk (about 40 g) of raw celery has roughly 6–7 calories. This calculator focuses on cup measurements, but you can enter the weight in grams to get an equivalent estimate.
Does celery juice have more calories than raw celery? Yes, per cup, because juice is more concentrated. A cup of raw chopped celery has about 16 kcal, while a cup of celery juice has about 50 kcal (236 g × 21 cal/100g).
Can I use this calculator for celery in soups or stews? Yes, select "cooked" for boiled celery. If the celery is cooked in oil or butter, add those calories separately.
