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.
117kg in UK Measurements and BMI Context
117 kilograms equals 18 stone 6.6 pounds using standard UK weight conversions. To understand what this means for your health, you need to calculate your BMI, which depends on your height. For example, at 5ft 8in (173cm), a weight of 117kg gives a BMI of approximately 41.5, which falls in the severely obese (Class III) category according to NHS guidelines. However, BMI varies significantly by height — someone 6ft tall (183cm) at 117kg would have a BMI of around 36.5. The NHS recommends a healthy BMI range of 18.5 to 24.9 for most adults, though lower thresholds apply for people of South Asian, Chinese, Black African, or Black Caribbean heritage.

Health Context and NHS Guidance at 117kg
At 117 kilograms, your GP may discuss weight management options depending on your individual health profile, height, and any weight-related health conditions. The NHS offers a structured weight management pathway starting with self-help and digital tools (tier 1), progressing to primary care-based programmes (tier 2), and specialist services (tier 3) where prescription weight loss medications may be considered. Weight loss of even 5–10% of your body weight — approximately 6–12kg — can meaningfully improve blood pressure, blood sugar control, and cardiovascular health. Sustainable weight loss typically targets 0.5–1kg per week alongside reduced-calorie eating and increased physical activity.
