A medium stalk of raw celery, measuring approximately 7.5 to 8 inches in length, contains about 0.6 grams of dietary fiber, which is approximately 2% of the daily value based on a standard diet (Nutritionix).

Additionally, if chopped, a cup of celery provides over 1.5 grams of fiber, illustrating its nutritional versatility (Verywell Fit). In contrast, a serving of celery can also have a varied fiber content based on the serving size; for instance, one cup may yield around 5 grams of dietary fiber (Healthline).

For reference, a different source specifies that one serving of celery (typically about 38 grams, which also can be thought of as a stalk) includes around 1.6 grams of dietary fiber (Nutrition Value). These fiber amounts indicate that celery can be a modest contributor to dietary fiber intake.

It's worth noting that depending on the preparation and serving size, fiber content can vary, but in general, celery remains a low-calorie vegetable beneficial for maintaining a balanced diet.
