About This Calculator
This calculator converts weight between stones (st) and kilograms (kg). It is useful for users working across both imperial and metric unit systems, particularly in healthcare, sports, and international contexts.
How It Works
The calculator uses the fixed relation: 1 stone = 6.35029318 kilograms. Depending on the selected direction, it multiplies or divides accordingly.
kg = st × 6.35029318
st = kg ÷ 6.35029318
st = kg ÷ 6.35029318
