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 150 Kg to Stone
Converting 150 kg to stone is straightforward using the standard conversion formula. One stone equals 6.35029 kilograms, so to convert kilograms to stone, you simply divide by 6.35029. For 150 kg: 150 ÷ 6.35029 = 23.63 stone, which equals 23 stone and 8.8 pounds (or approximately 23st 8lbs in UK measurements).
The same weight can also be expressed as 330.7 pounds in imperial measurements. You don't need to do the maths manually — our free weight converter above instantly converts between kilograms, stone, and pounds, and can help you switch between any UK and metric measurements. This is especially useful if you're working with NHS health guidance, which often uses kilograms clinically but many UK adults prefer to think in stone and pounds.

150 Kg Weight and UK Health Context
At 150 kg, your weight sits in a higher range. The NHS healthy weight guidance depends on your height — for most UK adults, a healthy weight range is a BMI of 18.5 to 24.9. To understand whether 150 kg is within a healthy range for you personally, you need to calculate your BMI, which factors in both weight and height. Use our free BMI calculator on this page to check your individual BMI instantly. If you're concerned about your weight or health, your GP can provide personalised advice and discuss weight management options tailored to your circumstances.
- At 5ft 8in (173 cm), 150 kg gives a BMI of approximately 44.7 (severely obese category)
- At 6ft 2in (188 cm), 150 kg gives a BMI of approximately 38.4 (obese category)

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 150 kg overweight or obese according to NHS guidelines?
Whether 150 kg is overweight or obese depends entirely on your height. BMI combines weight and height to give an accurate picture. You could calculate your BMI using the free calculator on this page to see your personal category according to NHS standards. Your GP can provide individual health advice based on your complete health profile.
What is the healthy weight range for someone 150 kg currently weighs?
There's no single "healthy weight" — it depends on your height and body composition. The NHS defines healthy weight as a BMI of 18.5–24.9. To find your healthy weight range for your height, use our free BMI calculator. Your GP can also discuss what a healthy target might be for your individual circumstances.
How do I convert 150 kg to stone and pounds accurately?
150 kg converts to 23 stone and 8 pounds (23st 8lbs). To convert any weight, divide kilograms by 6.35029 to get stone. Our free weight converter on this page does this instantly for any weight in any direction — between kg, stone, and pounds.
Should I be concerned about weighing 150 kg?
Health risk depends on many factors: your height, age, sex, muscle mass, medical history, and where weight is distributed. Rather than the number alone, your BMI and GP assessment matter. If you have concerns, speak to your GP who can assess your individual health and discuss whether any support or interventions might help.
What resources does the NHS offer for weight management if I weigh 150 kg?
The NHS offers support through several tiers: self-help resources and digital tools (tier 1), local weight management programmes (tier 2), and specialist services for more intensive support (tier 3–4). Your GP can refer you to appropriate local support and discuss weight management options relevant to your health needs.
