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.
Converting 165kg to Stone and Pounds
To convert 165kg to stone using the standard kg to stone conversion, divide by 6.35029. This gives you 26 stone and 0.3 lbs. In pounds only, 165kg is approximately 363.8 lbs.
- 165kg ÷ 6.35029 = 26.0 stone
- 165kg × 2.20462 = 363.76 lbs
- 26 stone × 14 = 364 lbs (exact equivalent)
UK adults typically use stone and pounds for body weight, while NHS clinical measurements are recorded in kilograms. Our free weight converter on this page lets you convert 165kg to any measurement unit instantly. Understanding both units is helpful when discussing your weight with your GP or comparing your weight against NHS healthy weight guidance.

165kg BMI and Healthy Weight Range
Your BMI depends on your height. For someone who is 1.75m (5ft 9in) tall, 165kg gives a BMI of approximately 53.9, which falls into the severely obese category according to NHS guidelines. A healthy BMI for this height would be between 18.5 and 24.9, equivalent to a healthy weight range of roughly 56kg to 76kg (8st 11lbs to 11st 13lbs).
