Limes are one of the lowest-calorie ways to add bright, citrusy flavor to water, marinades, sauces, and cocktails, but tracking calories can be tricky because you might measure by fruit, by juice, or by grams. This lime calories per serving calculator converts all of those measurements into a clear calorie estimate, and it can split the total across multiple servings — handy for recipes like lime vinaigrette, salsa, or a pitcher of limeade.
Just choose whether you are using lime juice, fresh lime flesh and pulp, or whole lime weighed with the peel, enter the amount in grams, ounces, milliliters, or whole medium limes, and set the number of servings. The tool calculates total calories, calories per serving, and weight per serving using standard USDA nutrition reference values: roughly 25 kcal per 100 g for lime juice and 30 kcal per 100 g for fresh lime flesh.
Use it for meal prep, macro counting, cocktail calorie tracking, or simply to understand how little a squeeze of lime actually changes your daily totals.
Quick Start
Select whether you are measuring lime juice, fresh lime flesh/pulp, or a whole lime with peel. Enter the amount in grams, ounces, milliliters, or whole limes, then set how many servings the batch will be divided into. Press Calculate and check the results below. Use the preset buttons to quickly fill common measurements.
How the Calculation Works
The tool starts from standard USDA nutrition values for limes. It converts your chosen unit to grams, multiplies by the calorie value per 100 g, then divides by the number of servings. For milliliters, it applies an approximate density so a volume measurement becomes a weight estimate.
grams = input amount × unit conversion (or whole limes × 67 g per medium lime)
total calories = grams ÷ 100 × kcal per 100 g
calories per serving = total calories ÷ servings
Reference Calorie Values
| Form / Item | Kcal per 100 g | Common household equivalent |
|---|---|---|
| Lime juice | 25 | 1 tbsp ≈ 15 g ≈ 4 kcal |
| Fresh lime flesh/pulp | 30 | 1 medium lime flesh ≈ 30 g ≈ 9 kcal |
| Whole lime with peel | 30 (approx.) | 1 medium lime ≈ 67 g ≈ 20 kcal |

Worked Examples
Example: Lime juice for a pitcher of limeade. You use 120 ml lime juice and split it into 4 glasses. 120 ml × 1.04 g/ml = about 125 g; 125 g × 25 kcal/100 g = 31.3 kcal total; divided by 4 servings = about 7.8 kcal per glass.
Example: Recipe with half a lime. Half of a medium whole lime weighs roughly 34 g. 34 g × 30 kcal/100 g = about 10 kcal total. If the recipe makes 2 servings, each serving contains about 5 kcal from the lime.
Tips for Accurate Tracking
- Use grams when possible; food scales give the most reliable measurements.
- Weigh whole limes before juicing if you are counting the entire fruit, or weigh the juice after squeezing if your recipe only uses juice.
- Fresh lime flesh includes pulp and membranes; if you discard the peel, choose fresh flesh rather than whole-lime values.
Frequently Asked Questions
How many calories are in one whole lime? A medium whole lime with peel weighs about 67 g and provides roughly 20 kcal. Most of that energy comes from carbohydrates, including fiber.
Is lime juice lower in calories than other citrus juices? Lime juice is similar to lemon juice at about 25 kcal per 100 g. Orange juice contains roughly 45–50 kcal per 100 g, so lime and lemon are among the lowest-calorie juice options.
Why do the results differ from my food scale app? Calorie databases can use different lime varieties, moisture contents, or portion sizes. This tool gives a consistent estimate; for clinical precision, use a specific product label (for example, USDA FoodData Central).
