1. "How much do you weigh?" <- This sounds most natural to a native English speaker. 2. "How many kilos do you weigh?" <- You might hear this from a native English speaker in a country using metric measurements. It's less common than "How much do you weigh?" 3. "How much is your weight?" <- This is grammatically correct, but it sounds unnatural to a native English speaker. "How much" is used with nouns that are uncountable. "How many" is used with nouns that countable. (In #2, the countable noun is "kilos")

Because weight is a singular noun, it would be "how much is your weight?" However when asking somebody else about their weight, we usually ask "How much do you weigh?"
