This Tangerine Vitamin C Calculator helps you quickly determine the vitamin C content of tangerines based on their weight or serving size. Whether you're tracking your daily micronutrient intake, planning a balanced diet, or simply curious about the nutritional value of this popular citrus fruit, this tool provides accurate estimates using standard nutritional data.
Tangerines are an excellent source of vitamin C, an essential antioxidant that supports immune function, collagen production, and iron absorption. By entering the weight of your tangerine(s) in grams or ounces, or by selecting a common serving size (e.g., one medium fruit, a cup of segments), you'll get an instant calculation of the vitamin C content in milligrams. The tool also shows the percentage of the recommended daily value (% DV) based on a 90 mg reference for adults, making it easy to see how tangerines contribute to your daily needs.

Step-by-step:
How to Use This Tool
Using the Tangerine Vitamin C Calculator is straightforward. Start by entering the weight of your tangerine(s) in grams or ounces. You can also click one of the preset buttons for common serving sizes: small (76 g), medium (88 g), large (109 g), or one cup of segments (195 g). After entering or selecting your data, click the blue "Calculate Vitamin C" button. The tool will display the vitamin C content in milligrams and the percentage of the Daily Value (% DV) based on a 90 mg reference for adults. A step-by-step breakdown shows the calculation process, making it easy to understand how the result is derived.
Tip: For the most accurate results, weigh your tangerine on a kitchen scale. If you don't have a scale, the preset buttons provide reliable estimates based on average fruit sizes from USDA data.
Formula Explained
The calculation uses the standard vitamin C density of tangerines: approximately 26.7 mg of vitamin C per 100 grams of edible fruit. This value is derived from the USDA FoodData Central database. The formula is:
Vitamin C (mg) = (26.7 mg / 100 g) × weight in grams
If you enter the weight in ounces, the tool first converts ounces to grams (1 oz = 28.3495 g) before applying the formula. The % Daily Value is then calculated as: (vitamin C in mg / 90 mg) × 100. The 90 mg reference is the Daily Value for vitamin C established by the U.S. Food and Drug Administration (FDA) for adults and children aged 4 years and older.
Worked Examples
Example 1: You eat one medium tangerine weighing 88 g. Vitamin C = (26.7 / 100) × 88 = 23.5 mg. % DV = (23.5 / 90) × 100 = 26.1%. So one medium tangerine provides about 26% of your daily vitamin C needs.
Example 2: You have a cup of tangerine segments (195 g). Vitamin C = (26.7 / 100) × 195 = 52.1 mg. % DV = (52.1 / 90) × 100 = 57.9%. That's over half of your daily requirement.
Example 3: You eat two large tangerines (109 g each, total 218 g). Vitamin C = (26.7 / 100) × 218 = 58.2 mg. % DV = (58.2 / 90) × 100 = 64.7%.
Factors Affecting Vitamin C Content
While the calculator uses a standard value of 26.7 mg per 100 g, actual vitamin C content can vary due to several factors:
- Variety: Different tangerine cultivars (e.g., Clementine, Honey, Satsuma) may have slightly different vitamin C levels. Clementines, for instance, average around 48 mg per 100 g, while Honey tangerines may be closer to 30 mg per 100 g.
- Ripeness: Vitamin C content tends to decrease as fruit ripens. Fresher, less ripe tangerines may have higher levels.
- Storage and handling: Vitamin C is sensitive to heat, light, and air. Prolonged storage or exposure can reduce levels. For maximum vitamin C, consume tangerines soon after purchase and store them in a cool, dark place.
- Part of the fruit: The peel contains more vitamin C than the flesh, but the calculator estimates only the edible portion (without peel). If you eat the zest, you may get additional vitamin C.
Frequently Asked Questions
Q: Are tangerines a good source of vitamin C compared to oranges?
A: Oranges contain about 53 mg of vitamin C per 100 g, nearly double the amount in tangerines. However, tangerines are still an excellent source, providing about 30% of the daily value per medium fruit. They also offer other nutrients like vitamin A, fiber, and antioxidants.
Q: Can I use this calculator for other citrus fruits?
A: No, this calculator is specifically calibrated for tangerines. For other citrus fruits like oranges, grapefruits, or lemons, you would need a different vitamin C density value. You can find general vitamin C calculators on our site for other fruits.
Q: Is the % DV based on a 90 mg reference suitable for everyone?
A: The 90 mg Daily Value is a general guideline for adults and children aged 4+. Individual needs may vary based on age, sex, pregnancy, breastfeeding, and health conditions. For personalized advice, consult a healthcare professional or dietitian.
Q: Does cooking affect vitamin C content?
A: Yes, vitamin C is heat-sensitive and water-soluble. Cooking tangerines (e.g., in marmalades or sauces) can significantly reduce their vitamin C content. For maximum vitamin C, eat tangerines raw and fresh.
Real-World Applications
This calculator is useful for dietitians, nutritionists, fitness enthusiasts, and anyone tracking their micronutrient intake. Vitamin C is crucial for immune health, collagen synthesis, wound healing, and iron absorption. By knowing how much vitamin C you get from tangerines, you can better plan your diet to meet daily requirements. For example, if you're aiming for 90 mg per day, eating three medium tangerines would provide about 78% of your needs, leaving room for other vitamin C-rich foods like bell peppers, broccoli, or strawberries.
For more detailed nutritional information about tangerines, you can refer to the USDA FoodData Central database. The FDA's Daily Value reference provides official guidelines for nutrient intake.
