Formula and method
Since the 1959 international yard and pound agreement, one avoirdupois pound is defined as exactly 0.45359237 kilograms. Dividing kilograms by that number gives pounds exactly; multiplying by 2.20462 is the same thing rounded to six significant figures.
For pounds and ounces, the total is multiplied by 16 to get ounces, split into whole pounds and the leftover ounces (rounded to 0.1 oz). Stone is pounds divided by 14, the UK unit used for body weight.
