Wondering how many calories are in that handful of tangerine segments? Our Tangerine Calories Per Ounce Calculator gives you an instant, accurate estimate based on the weight of the fruit you're about to enjoy. Whether you're tracking macros, planning a low-calorie snack, or just curious about portion sizes, this tool does the math for you.
Simply enter the weight of your tangerine (in ounces or grams) and the calculator returns the total calories, along with a breakdown of carbohydrates, sugars, and fiber. You can also work backward — enter a calorie target to see how many ounces of tangerine that equals. Perfect for meal preppers, dieters, and anyone who loves this juicy citrus fruit.
Built on USDA nutrition data, the tool uses a standard value of about 13.4 calories per ounce of raw tangerine. Use the quick-fill buttons to test common serving sizes, or input your own weight for precise tracking.

How to Use This Tool
Using the tangerine calorie calculator is straightforward. First, choose the calculation direction: either Weight → Calories or Calories → Weight. In the default mode, enter the weight of your tangerine in ounces or grams — the tool automatically converts grams to ounces using the standard conversion (1 oz = 28.35 g). Then click Calculate to see the total calories, plus a breakdown of carbohydrates, sugars, and fiber.
If you're planning a snack with a specific calorie budget, switch to Calories → Weight mode. Enter your target calories (e.g., 50 kcal) and the tool tells you how many ounces of tangerine that corresponds to. This is handy for portion control when you're counting calories or following a meal plan.
The quick-fill buttons let you instantly test common serving sizes: a medium tangerine (about 3.5 oz), 1 oz, or ½ oz. You can also use the reset button to clear all inputs and start fresh.
How It Works
The calculator uses USDA FoodData Central nutrition data for raw tangerines. According to the USDA, raw tangerines contain approximately 53 calories per 100 grams. Since 100 grams equals about 3.527 ounces, this translates to roughly 13.4 calories per ounce. The tool applies this constant to your input weight.
For the macronutrient breakdown, we use average values from the same USDA dataset: about 13.4 g of carbohydrates per 100 g (which is ~3.4 g per ounce), 10.6 g of sugars per 100 g (~2.7 g per ounce), and 1.8 g of fiber per 100 g (~0.5 g per ounce). These values are typical for fresh, raw tangerines without the peel.
The formula is simple: Calories = Weight (oz) × 13.4. For the reverse calculation, Weight (oz) = Calories ÷ 13.4. The tool rounds results to one decimal place for readability.
Worked Examples
Example 1: You have a small tangerine that weighs 2.5 oz. Calories = 2.5 × 13.4 = 33.5 kcal. Carbs = 2.5 × 3.4 = 8.5 g, sugars = 2.5 × 2.7 = 6.75 g, fiber = 2.5 × 0.5 = 1.25 g.
Example 2: You want a 60-calorie snack. Weight = 60 ÷ 13.4 = 4.48 oz. That's about 127 grams — roughly one large tangerine or two small ones.
Example 3: You weigh your tangerine in grams and get 150 g. Convert to ounces: 150 ÷ 28.35 = 5.29 oz. Calories = 5.29 × 13.4 = 70.9 kcal.
Tips & Best Practices
- Weigh without the peel: The calorie values apply to the edible flesh only. If you weigh the whole fruit, subtract the peel weight (typically 30–40% of total weight) for accuracy.
- Use a kitchen scale: For precise tracking, weigh your tangerine segments on a digital scale. Eyeballing portion sizes can lead to underestimating calories by 20% or more.
- Consider ripeness: Sweeter, riper tangerines may have slightly higher sugar content, but the calorie difference is minimal — usually within 5%.
- Pair with protein: Tangerines are mostly carbs, so pairing them with a handful of almonds or a boiled egg can make a more balanced snack.
Factors Affecting Accuracy
The calorie values are averages from USDA data and can vary slightly depending on the specific variety of tangerine (e.g., clementines, mandarins, or tangelos), growing conditions, and ripeness. The difference between varieties is typically small — usually less than 10% — so the calculator remains a reliable estimate for most purposes.
Another factor is the edible portion. If you eat the pith (the white part), you'll get a bit more fiber, but the calorie difference is negligible. For the most accurate tracking, always weigh the flesh you actually consume.
Frequently Asked Questions
How many calories are in a whole tangerine? A medium tangerine (about 3.5 oz of flesh) contains roughly 47 calories. Larger fruits can reach 60–70 calories.
Are tangerines good for weight loss? Yes. Tangerines are low in calories and high in water and fiber, which help you feel full. A typical serving is only 40–60 calories, making them an excellent sweet snack for calorie-controlled diets.
Do tangerines have a lot of sugar? A medium tangerine has about 9–10 grams of natural sugar. While this is relatively high for fruit, the fiber and water content help moderate blood sugar spikes compared to processed sweets.
Can I use this calculator for clementines or mandarins? Yes. Clementines and mandarins have very similar nutrition profiles to tangerines, so the calorie estimate will be accurate within a few calories.
Where does the nutrition data come from? The values are based on the USDA FoodData Central database, which is the standard reference for nutrition information in the United States. You can explore the full dataset at fdc.nal.usda.gov.
