Calories and macros per 100 g
All values are for the edible portion in the stated food state.

| Serving | Weight | State | Kcal | Protein | Fat | Carbs |
|---|---|---|---|---|---|---|
| 1 long cucumber | 301 g | Raw, with peel | 45.15 | 1.96 g | 0.33 g | 10.93 g |
| 1 cup sliced cucumber | 104 g | Raw, with peel | 15.6 | 0.68 g | 0.11 g | 3.78 g |

What affects the calorie value
Raw cucumber with peel contains a high proportion of water, so calories per 100 g are low. Dressing, oil or sauce still need to be counted separately.
Pickled and salted cucumbers should not be calculated from the raw record. Brine, sugar and water changes produce a different composition, especially for sodium.
Vitamins and minerals per 100 g
Values come from the same USDA records. They show the amount in the food, not a percentage of an individual daily requirement.
| Nutrient | Raw, with peel |
|---|---|
| Vitamin K, µg | 16.4 |
| Potassium, mg | 147 |
| Magnesium, mg | 13 |
| Calcium, mg | 16 |
| Vitamin C, mg | 2.8 |
| Folate, µg | 7 |
How to calculate more accurately
Weigh after removing ends and other parts you will not eat.
This record is for raw cucumber with peel. Pickled, salted and peeled cucumbers have different composition.
Most cucumber weight is water, but calories are not zero. Count salad dressing separately.
Common questions
Can I calculate a whole cucumber?
Yes. Enter its edible weight in grams instead of the default 100 g.
How many calories are in a whole cucumber?
A long cucumber weighing about 301 g provides roughly 45 kcal. Smaller cucumbers are best weighed separately.
Does peeling a cucumber change the values?
Yes. Composition changes slightly, including fibre and vitamin K. This page uses the record for cucumber with peel.
Can a pickled cucumber be counted as raw?
No. Use a separate database item or the jar label because the marinade changes the composition.
Data source and accuracy

Serving calculation: value per 100 g × serving weight / 100. Calories come from the stated source, not from rounded macros. USDA total carbohydrate includes fibre. Do not add fibre again.
For packaged foods, prefer the label. Calculate cooked dishes from their ingredients and actual yield. This reference does not prescribe medical diets.
