Peas are a versatile and nutritious vegetable, but did you know they also contribute to your daily vitamin C intake? This calculator helps you estimate the vitamin C content in various types of peas — green peas, snow peas, and sugar snap peas — based on the amount you plan to eat. Whether you're tracking micronutrients for a balanced diet, meal prepping, or simply curious about the nutritional profile of your favorite legume, this tool provides quick and accurate results.
Simply select the type of pea, enter the serving size in grams or cups, and the calculator will compute the vitamin C content along with a percentage of the recommended daily value (based on 90 mg for adult men and 75 mg for adult women). Use the preset buttons for common serving sizes to speed things up. Perfect for nutrition enthusiasts, dietitians, and anyone aiming to meet their daily vitamin C goals through whole foods.

How to Use This Tool
Using the Pea Vitamin C Calculator is straightforward. Start by selecting the type of pea you have — green peas, snow peas, or sugar snap peas — from the dropdown menu. Then enter the amount you plan to eat, either in grams or cups. The calculator automatically converts cups to grams using an approximate density (1 cup ≈ 160 g for loosely packed peas). For quick entry, click one of the preset buttons (50 g, 100 g, 150 g, 200 g). Finally, click "Calculate Vitamin C" to see the vitamin C content in milligrams and the percentage of the recommended daily value for both men (90 mg) and women (75 mg).
Formula Explained
The calculation is based on the vitamin C content per 100 grams of raw peas, sourced from the USDA FoodData Central database. The formula is:
Vitamin C (mg) = (Vitamin C per 100g / 100) × amount in grams
For example, green peas contain approximately 40 mg of vitamin C per 100 g. If you eat 150 g of green peas, the vitamin C content is (40 / 100) × 150 = 60 mg. The daily value percentages are then computed by dividing the result by the reference daily intake (90 mg for adult men, 75 mg for adult women) and multiplying by 100.
Worked Examples
Example 1: 100 g of snow peas. Snow peas have 60 mg vitamin C per 100 g. Vitamin C = (60/100) × 100 = 60 mg. DV for men: 60/90 × 100 = 66.7%. DV for women: 60/75 × 100 = 80%.
Example 2: 1 cup of sugar snap peas (≈160 g). Sugar snap peas have 60 mg per 100 g. Vitamin C = (60/100) × 160 = 96 mg. DV for men: 96/90 × 100 = 106.7%. DV for women: 96/75 × 100 = 128%.
Example 3: 50 g of green peas. Vitamin C = (40/100) × 50 = 20 mg. DV for men: 22.2%. DV for women: 26.7%.
Factors Affecting Vitamin C Content
Vitamin C is sensitive to heat, light, and air. Cooking peas (boiling, steaming, microwaving) can reduce vitamin C content by 20–50% depending on the method and duration. Frozen peas are typically blanched before freezing, which may cause some loss, but they still retain a good amount of vitamin C. Canned peas often have lower vitamin C due to the high-heat processing. For the most accurate intake, use raw pea values and adjust downward if cooking. The calculator uses raw values; if you are eating cooked peas, consider reducing the result by 25–40% as a rough estimate.
Real-World Applications
Vitamin C is essential for immune function, collagen synthesis, and antioxidant protection. Peas are a convenient way to add vitamin C to meals — toss them into salads, stir-fries, soups, or serve as a side dish. For individuals following plant-based diets, peas contribute to meeting daily vitamin C needs without relying solely on citrus fruits. This calculator is also useful for meal planners and dietitians who need precise micronutrient data for recipe analysis or dietary assessments.
Frequently Asked Questions
Are frozen peas as high in vitamin C as fresh peas? Frozen peas are usually blanched, which causes some vitamin C loss, but they still contain a significant amount — often around 70–80% of fresh values. Check the package for specific nutrition information.
Can I use this calculator for cooked peas? The calculator uses raw pea values. For cooked peas, you can manually reduce the result by about 30% to account for heat degradation. For more precise data, refer to the USDA FoodData Central entry for cooked peas.
What about dried or split peas? Dried peas have a much lower vitamin C content because the drying process degrades vitamin C. This calculator is intended for fresh or frozen peas only.
How does pea vitamin C compare to other vegetables? Green peas (40 mg/100g) are a moderate source — similar to broccoli (89 mg/100g) but lower than bell peppers (128 mg/100g) or kale (120 mg/100g). Snow peas and sugar snap peas are slightly higher at 60 mg/100g.
