What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
104kg to Stone Conversion & Formula
104 kg = 16 stone 5.6 lbs (or 16st 5.6lbs)
To convert kilograms to stone, divide the kilogram value by 6.35029. The formula is: kg ÷ 6.35029 = stone. For 104kg: 104 ÷ 6.35029 = 16.39 stone. To express this in stone and pounds, multiply the decimal by 14 (since 1 stone = 14 pounds): 0.39 × 14 = 5.6 lbs.
Use our weight converter above to instantly convert 104kg to stone, or any other weight value between kg, stone, and pounds.
- 104 kg = 16.39 stone (decimal)
- 104 kg = 229 pounds
- Rounded: approximately 16 stone 6 pounds
