How many carbs in cucumber?

Cucumbers do contain carbohydrates, but in very low amounts. In fact, some low-carb diets recommend using cucumber slices in place of crackers and chips when eating dips and spreads. Much of the low carbohydrate content in cucumbers is in the peel, please know.

A medium-sized cucumber (of approximately eight-inch length) contains 9 grams of carbohydrates, along with 2 grams of fiber and 45 calories. Without the peel, that same cucumber has only 4 grams of carbohydrates and 34 calories, but the same 2 grams of fiber.
