If you want to be a soldier this year, you will gain weight. My height is 180CM and my weight is 8 1KG. I don't know if I can meet the requirements of being a soldier and how much thinner I have to be. Male: Not more than 25% of the standard weight and not less than 15% of the standard weight.

Standard weight = (height-1 10) kg.

Your height is 180. The standard weight is 70kg, the upper limit is 87,5 kg and the lower limit is 59.5kg!

Therefore, according to the conditions you gave, it meets the weight requirements of the conscription physical examination!

But don't forget, conscription is not just about weight. The whole physical examination involves internal medicine, surgery, otolaryngology, ophthalmology, psychological tests, and more than 50 examinations!
