Using this food reference
The romaine record is raw cos lettuce. Its shredded-cup comparison describes the leaves alone rather than a dressed salad or a whole head.
A loose cup and a tightly packed bowl need not contain the same weight of leaves. Use grams to compare the reference, then account for dressing, cheese and other salad ingredients separately.
Match the food before using the numbers
The selected USDA description is Lettuce, cos or romaine, raw. Preparation, water loss, added oil, salt, edible skin, product formulation, and measured portion can change the nutrition of the food you actually eat.
