Celery is famous for being crunchy, hydrating, and low in calories, but it is often overlooked as a source of vitamin C. A 100-gram serving of raw celery provides about 3.1 mg of ascorbic acid — a modest amount that can still add up when celery appears in soups, salads, snacks, and juice blends. This calculator converts any portion of celery into its vitamin C content and shows how that portion contributes to the recommended daily value.
Whether you're tracking micronutrients for general health, managing a specific dietary plan, or simply curious about how celery compares with other produce, this tool gives you an instant, evidence-based answer. Enter an amount in grams, ounces, chopped cups, or medium stalks, and the calculator will return the total vitamin C in milligrams and as a percentage of the daily value.
Celery Vitamin C Calculator
Find out how much vitamin C is in any amount of celery and how much of your daily need it covers.
How to Use This Tool
This calculator is designed for quick, no-fuss vitamin C estimates. Start by choosing the unit that matches how you measure celery: grams, ounces, chopped cups, or medium stalks. Type the amount into the first field, then click Calculate vitamin C. The result area shows the total vitamin C in milligrams, the weight in grams, and the percentage of the Daily Value based on a 90 mg target.
If you want to test common portions quickly, use the preset chips above the button. One click fills in a typical serving such as one medium stalk or one cup of chopped celery and calculates it immediately. The reset button clears all fields and restores the default state.
🧪 Formula Explained
The calculation relies on one core nutritional value: raw celery contains about 3.1 mg of vitamin C per 100 grams, according to USDA FoodData Central. Once the portion is converted to grams, the formula is:
To convert the result into a Daily Value percentage, divide the milligrams by 90 mg and multiply by 100. The 90 mg figure matches the FDA Daily Value for vitamin C used on Nutrition Facts labels. For unit conversions, 1 ounce equals 28.35 g, 1 cup of chopped celery equals approximately 101 g, and one medium stalk (about 8 inches long) equals 40 g.
Worked Examples
Example 1: Two cups of chopped celery. 2 cups × 101 g = 202 g. Vitamin C = (202 ÷ 100) × 3.1 = 6.26 mg. That equals 6.3 mg, or about 7.0% of the Daily Value.
Example 2: Three medium stalks. 3 × 40 g = 120 g. Vitamin C = (120 ÷ 100) × 3.1 = 3.72 mg. That works out to roughly 4.1% of your daily vitamin C target.
Example 3: A 50 g snack portion. Half a cup of chopped celery is about 50 g. Vitamin C = 0.5 × 3.1 = 1.55 mg, or 1.7% of the Daily Value. These numbers show why celery is better viewed as a supporting player rather than a primary vitamin C source.
Standard Values Table
The table below summarizes common celery portions and their approximate vitamin C content using the 3.1 mg per 100 g value.
| Portion | Approx. weight | Vitamin C | % Daily Value |
|---|---|---|---|
| 1 medium stalk (8 in) | 40 g | 1.24 mg | 1.4% |
| 1 large stalk (11 in) | 64 g | 1.98 mg | 2.2% |
| 1 oz | 28.35 g | 0.88 mg | 1.0% |
| 1 cup chopped | 101 g | 3.13 mg | 3.5% |
| 100 g | 100 g | 3.10 mg | 3.4% |
Tips & Best Practices
- Fresh is best. Vitamin C is sensitive to heat, light, and oxygen, so celery that has been stored for a long time or cooked for a long time will contain less than the fresh raw value.
- Pair it with iron. Vitamin C helps your body absorb non-heme iron from plant foods, so adding raw celery to a bean or lentil dish can be a small but useful boost.
- Use celery as a low-calorie vehicle. Even though celery alone is not a vitamin C powerhouse, it pairs beautifully with dips like hummus, yogurt, or citrus-based dressings that add more of the vitamin.
- Compare with other produce. If you are specifically trying to raise your vitamin C intake, fruits and vegetables like apricots, cranberries, citrus, kiwis, broccoli, and bell peppers tend to offer more per serving. Try the apricot vitamin C calculator or the cranberry vitamin C calculator to see how different foods stack up.
❓ Frequently Asked Questions
Is celery a good source of vitamin C?
Celery provides a modest amount of vitamin C, but not enough to be considered a rich source. A full cup of chopped celery supplies roughly 3% of the Daily Value, while citrus fruits and peppers supply much more per serving.
Does cooking celery destroy vitamin C?
Yes, some vitamin C is lost when celery is heated, especially when boiled in water. Steaming or stir-frying for a short time preserves more, and eating celery raw gives the highest vitamin C content.
How much celery would I need to meet the full Daily Value?
At 3.1 mg per 100 g, you would need about 2,903 g of raw celery, or roughly 29 cups chopped, to reach 90 mg. That is far more than most people would eat, which is why celery is best combined with other vitamin C-rich foods. The 90 mg figure is the adult Daily Value used by the FDA. For more detail on vitamin C requirements, see the NIH Office of Dietary Supplements.
Can I use this calculator for celery juice or celery powder?
The calculator uses the standard raw celery value. For celery juice, estimate the number of stalks used; for dried celery powder, the vitamin C per gram is different because water is removed, so the raw stalk value should not be applied directly.
