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.
How to Convert 118 kg to Stone and Pounds
To convert kilograms to stone, divide the kilogram amount by 6.35029. For 118 kg: 118 ÷ 6.35029 = 18.58 stone. To express this as stone and pounds, multiply the decimal (0.58) by 14 (since 1 stone equals 14 pounds): 0.58 × 14 = 8.4 lbs. Therefore, 118 kg = 18 stone 8.4 pounds.
The conversion formula is: weight in kg ÷ 6.35029 = weight in stone. You can use our free weight converter on this page to switch between kg, stone, and pounds instantly for any weight value.
- 118 kg = 18st 8.4lbs
- 119 kg = 18st 10.6lbs
- 120 kg = 18st 12.8lbs
- 121 kg = 19st 1.0lbs
- 122 kg = 19st 3.2lbs

118 kg — BMI and Health Context
At 118 kg, your health status depends entirely on your height. For example, at 5ft 8in (173 cm), 118 kg gives a BMI of approximately 39.5, which falls in the obese range. At 6ft 2in (188 cm), the same weight gives a BMI of around 31.6. The NHS recommends a healthy BMI between 18.5 and 24.9 for most UK adults, though lower thresholds apply for South Asian, Chinese, Black African, and Black Caribbean populations. Try our BMI calculator above to find your personal BMI at 118 kg — this helps determine whether weight management support might be beneficial for you.
