Lychees are a juicy tropical fruit loved for their floral sweetness, but when you're tracking calories, their weight can be tricky to estimate. This lychee calories per ounce calculator takes the guesswork out of portion math: enter your amount in ounces, grams, whole lychees, or cups, and it instantly converts the weight into calories using per-100g nutrition data.
The tool supports both fresh raw lychee and canned lychee in syrup, since their calorie densities differ noticeably. It also shows calories per ounce, total weight in grams, and the percent of a 2,000-calorie daily intake — handy for meal prep, fruit bowls, snacks, or dessert planning.
Whether you're counting macros, planning a light snack, or just curious how many calories are in a handful, this calculator gives you a quick, reliable estimate in seconds.

📊 Nutrition Results
Step-by-Step Guide
Using this calculator takes only a few seconds. First, choose the unit that matches how you are portioning lychees: ounces if you are weighing a bowlful on a kitchen scale, grams for a digital food scale, whole lychees for a quick handful, or cups when following a recipe. Enter the number in the amount field, select fresh raw or canned in syrup, then press Calculate Calories.
The results panel shows total calories, the equivalent weight in grams and ounces, calories per ounce, and the share of a 2,000-calorie daily diet that your serving represents. The Reset button clears all fields and returns the quick-fill presets to their default state, so you can run several comparisons in a row.
How the Calories Are Calculated
Nutrition data for fruit is expressed per 100 grams, so the calculator first converts your chosen unit into grams. One ounce equals 28.3495 g; one whole peeled lychee has about 9.92 g of flesh; and one cup of prepared lychee weighs about 190 g. Once the total weight is known, the tool applies the standard formula:
Calories = (weight in grams ÷ 100) × kcal per 100 g.
The calorie densities come from USDA FoodData Central: fresh raw lychee is about 66 kcal per 100 g, while canned lychee in syrup is about 76 kcal per 100 g. That means one ounce of fresh lychee provides 28.3495 ÷ 100 × 66 ≈ 18.7 kcal, and one ounce of canned lychee in syrup provides 28.3495 ÷ 100 × 76 ≈ 21.5 kcal. These per-ounce values are displayed directly in the results.
Reference Table
The table below summarizes typical calorie values for common lychee portions. Use it to sanity-check the calculator's output.
| Portion | Fresh raw | Canned in syrup |
|---|---|---|
| 1 oz (28 g) | 19 kcal | 22 kcal |
| 100 g | 66 kcal | 76 kcal |
| 1 lychee (10 g flesh) | 7 kcal | 8 kcal |
| 1 cup (190 g) | 125 kcal | 144 kcal |
| 8 oz (227 g) | 150 kcal | 172 kcal |
Worked Examples
Example 1 — Fresh lychees by weight: A 4 oz bowl of fresh lychee equals 113.4 g. Using 66 kcal per 100 g, the calories are 113.4 ÷ 100 × 66 ≈ 74.8 kcal. That's a very reasonable snack, especially compared with a handful of dried fruit.
Example 2 — Whole fruit portion: If you eat 15 fresh lychees, the calculator treats that as 15 × 9.92 = 148.8 g of flesh, giving 148.8 ÷ 100 × 66 ≈ 98 kcal. Fifteen lychees is a generous bowl without wrecking your daily calorie budget.
Example 3 — Canned lychees in a recipe: A recipe calls for 1.5 cups of canned lychee in syrup. That equals 285 g, so the calorie total is 285 ÷ 100 × 76 ≈ 216.6 kcal for the whole recipe. If you are splitting a dessert four ways, each serving is about 54 kcal from the lychees alone.
Tips for Accurate Portions
- Weigh only the edible flesh — remove the peel and pit before weighing, since those parts are not included in the per-100 g values.
- For canned lychee, drain the syrup thoroughly before weighing; leftover syrup adds extra sugar calories.
- Frozen lychee without added sugar has nearly the same calories as fresh. Always read the label to check for sweetened syrup.
- Lychee size varies; if your fruit is unusually large or small, weighing it once will give you a good personal average.
Frequently Asked Questions
Do the peel and pit affect the calorie count?
No. The per-100 g nutrition values refer to the edible flesh only. The skin and seed are not digested, so they are excluded from the calorie math. Weighing shelled fruit will always overestimate calories if you do not subtract the peel and pit.
How many lychees make 100 g?
Because one average peeled lychee has about 9.92 g of flesh, 100 g is roughly 10 medium fruit. Larger varieties may give you only 7–8 per 100 g, while smaller ones can give 12–14.
Are canned and fresh lychees that different nutritionally?
Fresh lychee is about 66 kcal per 100 g, while canned lychee packed in heavy syrup is about 76 kcal per 100 g. The difference comes almost entirely from added sugar. If the can is labeled "lite" or "no sugar added," the calorie density will be closer to fresh fruit.
Why do brands sometimes show slightly different numbers?
Calorie counts vary with variety, growing region, ripeness, and processing. The USDA values used here are a reliable middle estimate, and results should be treated as accurate to within roughly ±5 kcal per 100 g.
