Tangerines are a refreshing, portable citrus fruit that contribute a modest but meaningful amount of calcium to your diet. A 100 g serving of raw tangerine flesh — just over one medium fruit — supplies roughly 37 mg of calcium, about 4% of the recommended daily intake for adults. This calculator converts any quantity of tangerines, from a single segment snack to a full cup of segments, into its calcium content so you can track micronutrients accurately.
Whether you are meal-prepping, following a bone-health plan, or simply curious about your fruit intake, this tool lets you enter weight in grams or ounces, or count by medium tangerines, large tangerines, or cup portions. Add your personal daily calcium target for a percentage breakdown, and see exactly how many grams (or medium tangerines) you would need to hit that target.
Use the quick-fill buttons for instant estimates, then adjust the quantity to match your portion.

Why Tangerine Calcium Matters
Calcium is the most abundant mineral in the human body, and meeting your daily target supports bone strength, muscle function, and nerve signaling. Tangerines deliver a small but helpful contribution: one medium fruit provides about 33 mg, roughly 3% of a 1000 mg reference daily intake. Unlike isolated supplements, whole fruit provides calcium in a matrix of vitamin C, potassium, folate, and soluble fiber, making it a refreshing snack that adds micronutrient variety without many calories.
Because portions vary so widely — a few segments, a lunchbox fruit, a packed cup — converting tangerines to calcium is not always intuitive. This calculator helps you compare a tangerine snack with other calcium sources, plan daily menus for bone health, or log micronutrients in a nutrition app. If you are also tracking energy from this fruit, combine the results with the Tangerine Calorie Calculator to keep calories and calcium in the same picture.
How the Calculator Works
The tool converts your portion into grams of edible flesh using common serving equivalents: 1 oz = 28.35 g, 1 medium tangerine = 88 g, 1 large tangerine = 120 g, and 1 cup of segments = 195 g. It then applies the constant 0.37 mg calcium per gram of raw tangerine flesh.
Calcium (mg) = portion quantity × grams per unit × 0.37 mg/g
Your daily target is used only to express the result as a percentage and to estimate how many tangerines would meet that target. The default of 1000 mg matches the calcium RDA commonly used for adults, but you can change it to 800, 1200, or another value recommended by your health care provider.
Step-by-Step Example
Example 1: 2 cups of tangerine segments.
1 cup = 195 g, so 2 cups = 390 g.
Calcium = 390 g × 0.37 mg/g = 144.3 mg.
Percent of 1000 mg target = 14.4%.
Example 2: 3 medium tangerines.
3 × 88 g = 264 g.
Calcium = 264 × 0.37 = 97.7 mg.
You would need about 10.2 medium tangerines to reach a 1000 mg target using only this fruit.
Reference Table: Tangerine Calcium Values
These values are rounded and assume raw, peeled tangerine flesh.
| Portion | Edible weight | Calcium |
|---|---|---|
| 1 small tangerine (2.25 in) | 76 g | 28 mg |
| 1 medium tangerine (2.5 in) | 88 g | 33 mg |
| 1 large tangerine (3 in) | 120 g | 44 mg |
| 1 cup segments | 195 g | 72 mg |
| 100 g | 100 g | 37 mg |
| 1 oz | 28 g | 10 mg |
Tips for Tracking Calcium
- Weigh the peeled segments, not the whole fruit with rind. The peel and pith are usually not eaten and will overstate your portion.
- When using piece counts, choose the size that matches your fruit. Tangerines range from about 76 g to 120 g depending on variety and harvest.
- Tangerines should complement, not replace, high-calcium foods. A medium tangerine has about one-tenth the calcium of a glass of milk.
- Pair tangerines with leafy greens, tofu, yogurt, fortified plant milk, almonds, or canned fish with bones to reach your daily target.
- Calcium needs are higher in adolescence, pregnancy, and after menopause. Check national guidelines or ask a dietitian for your personal target.
Frequently Asked Questions
How much calcium is in one tangerine? A medium tangerine (about 88 g) provides roughly 33 mg of calcium. A small one gives about 28 mg, and a large one about 44 mg.
Can tangerines help me meet my daily calcium needs? They can contribute, but you would need around 10 medium tangerines to reach a 1000 mg target. A practical approach is to treat tangerines as a nutrient-dense snack alongside other calcium-rich foods.
Do canned mandarin oranges have the same calcium? Not always. Canned segments packed in juice or syrup have a different water content and may contain less calcium per 100 g; check the nutrition label for the exact value.
Is the calcium in tangerines well absorbed? Calcium in citrus fruits is generally bioavailable, and the vitamin C present may also enhance iron absorption from a meal, which is useful if you are watching both minerals. For more on calcium requirements and food sources, see the NIH Office of Dietary Supplements calcium fact sheet or search the USDA FoodData Central database for updated nutrient values.
