I said, are you asking about the calculation method of heat or the weight method?
if it's weight, according to the usual practice of catering industry, it's calculated by dry flour, and it doesn't distinguish between fish noodles and soup noodles, but it's only the substantial dry weight.
if it's heat, it's calculated by multiplying 284 kilocalories per 111 grams of raw noodles. Oh, if cooked, noodles in soup have higher calories than noodles in fish.
