Celery is a famously low-calorie vegetable, but the exact number of calories in a serving depends on how you measure it — by stalk, by cup, or by weight. This calculator lets you enter your serving size in any common unit (stalks, cups, grams, or ounces) and instantly see the calorie count, along with a breakdown of carbohydrates, fiber, and net carbs.
Whether you're tracking calories for weight loss, counting carbs for a low-carb diet, or just curious about your snack, this tool gives you accurate, per-serving nutrition data. It's perfect for meal planning, diet logging, and healthy eating. Use the quick-fill buttons to try common serving sizes, or enter your own values for precise results.
🥬 Celery Nutrition Calculator
How to Use This Tool
Enter the amount of celery you plan to eat, choose the unit (stalk, cup, grams, or ounces), and click Calculate. The calculator instantly shows the total calories, plus a breakdown of carbohydrates, fiber, and net carbs. You can also use the quick-fill buttons for common serving sizes like one medium stalk or one cup of chopped celery.
For the most accurate results, weigh your celery on a kitchen scale and enter the weight in grams. If you don't have a scale, use the stalk or cup options — these are based on standard USDA reference amounts.
How It Works
The calculator uses standard nutrition data for raw celery. Per 100 grams, raw celery contains approximately 16 calories, 3.0 g carbohydrates, and 1.6 g fiber. These values come from the USDA FoodData Central database, which is the authoritative source for food composition data in the United States.
To calculate your serving, the tool first converts your chosen unit to grams using these conversions:
- 1 medium stalk (7-8 inches long) = 40 g
- 1 cup chopped = 101 g
- 1 ounce = 28.35 g
Then it multiplies the grams by the per-gram values for calories, carbs, and fiber. Net carbs are calculated as total carbs minus fiber, which is useful for low-carb and keto dieters.
Worked Examples
Example 1: You eat 2 medium stalks of celery. Each stalk is 40 g, so total weight is 80 g. Calories = 80 × 0.16 = 12.8 kcal. Carbs = 80 × 0.03 = 2.4 g. Fiber = 80 × 0.016 = 1.28 g. Net carbs = 2.4 − 1.28 = 1.12 g.
Example 2: You snack on 150 g of celery sticks. Calories = 150 × 0.16 = 24 kcal. Carbs = 4.5 g, fiber = 2.4 g, net carbs = 2.1 g.
Tips & Best Practices
- Celery is about 95% water, so it's very low in calories but still provides crunch and volume — great for satisfying hunger without breaking your calorie budget.
- If you're tracking calories for weight loss, remember that dips, peanut butter, or cream cheese add significant calories. A tablespoon of peanut butter adds about 94 kcal, so account for those extras.
- For consistent tracking, always use the same unit. Weighing in grams is the most reliable method.
- Celery is a good source of vitamin K and provides small amounts of folate and potassium, though the amounts per serving are modest.
Factors Affecting Accuracy
The nutrition values are averages from the USDA database. Actual values can vary slightly depending on the variety of celery, growing conditions, and how fresh it is. The stalk size can also vary — a very large stalk might weigh 50 g or more, while a small one could be 30 g. If precision matters, weigh your celery.
Also note that cooking celery (e.g., in soups or stir-fries) can change its water content and nutrient density, but the calorie difference is minimal since celery is so low in calories.
Frequently Asked Questions
Is celery a negative-calorie food?
No. The idea that celery burns more calories to digest than it provides is a myth. Celery is very low in calories (about 16 kcal per 100 g), but digestion still requires fewer calories than the food provides. It's a great low-calorie snack, but not negative-calorie.
How many calories are in a whole celery stalk?
A medium stalk (40 g) contains about 6.4 kcal. A large stalk (50 g) would be about 8 kcal.
Can I use this for celery juice?
Celery juice is typically made from about 1 bunch (around 400-500 g) of celery. That would provide roughly 64-80 kcal, but juicing removes most of the fiber, so the net carb count would be higher than for whole celery.
Is celery good for a low-carb diet?
Yes. With only about 1.4 g net carbs per 100 g, celery is very low in carbs and fits easily into keto and low-carb meal plans.
