2 stone is exactly 12.70 kilograms, which is 28 pounds. The maths is 2 × 6.35029 = 12.70058 kg, rounded to 12.70 kg.
In my experience this is a weight people look up for someone else far more often than for themselves: a toddler finding their feet, a chunky cat or small dog fresh from the vet's scale, a suitcase nudging a budget airline's limit. It sits well below adult ranges, so the number on its own says very little. For a child it belongs on an age- and sex-specific growth chart rather than an adult table like our BMI calculator, and any worry about a child's weight is one for a health visitor or GP.
