What The Kg To Stone Converter Works Out
- Stone and pounds: one stone is exactly 14 pounds and one kilogram is 2.2046 pounds, so kilograms are divided by 6.35029 to get stone, with the remainder shown in pounds. 80 kg is 176.4 lb, which is 12 st 8.4 lb. The mental shortcut is to double the kilograms (slightly over) and divide by 14.
- Stone (decimal): the same weight as a decimal number of stone, the form some charts and apps use. 80 kg is 12.60 st.
- Pounds: total pounds, as used in the US and on many gym machines. One pound is exactly 0.45359237 kg, so the converter is accurate far beyond what bathroom scales can measure.
- Stone to kg mode: enter stone and pounds to get kilograms and grams, the units your GP, hospital and most medication doses work in. 12 st 8 lb is 79.8 kg.
- Reference table: the common adult range at a glance, which you can re-centre and re-space in the advanced options (for example 2 kg steps from 60 kg, or a children's range from 10 kg).
- BMI (advanced): weight in kilograms divided by height in metres squared, with the NHS adult bands: under 18.5 underweight, 18.5 to 24.9 healthy, 25 to 29.9 overweight, 30 and over obese. BMI is a screening guide rather than a diagnosis and can overstate fat for muscular people; the NHS suggests lower thresholds for some ethnic groups.
- Healthy weight range (advanced): the weights that give a BMI of 18.5 to 24.9 at your height, in both kilograms and stone and pounds.
- To reach your target (advanced): the gain or loss needed to hit a target weight, in kilograms and in stone and pounds. A safe sustainable rate is usually quoted as 0.5 to 1 kg (1 to 2 lb) a week.
- Pounds and ounces (advanced): the weight as whole pounds and ounces (16 to the pound), the form used for babies and for recipes and parcels.
- Precision (advanced): show pounds to the nearest whole pound or to one or two decimal places throughout.
