I said, are you asking about the calculation method of calories, or the weight method?

If it is weight, according to the customary practice in the catering industry, the weight is calculated based on dry flour. There is no distinction between lo mein and soup noodles. It is just the actual weight of dry goods.

If it is calories, it is calculated by multiplying 284 kcal per 100 grams of raw noodles. Oh, if cooked, the calories of noodle soup are higher than that of lo mein.
