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.
150kg to Stone Conversion Formula and Table
To convert 150kg to stone, divide the kilogram figure by 6.35029. The formula is straightforward: kg ÷ 6.35029 = stone. For 150kg, this gives exactly 23.622 stone, which breaks down as 23 stone and 8.7 pounds (or approximately 23st 8lbs in everyday terms).
Here's a handy reference table showing 150kg alongside nearby weights in both stone and kilograms:
- 145kg = 22st 11.8lbs
- 147kg = 23st 2.2lbs
- 150kg = 23st 8.7lbs
- 153kg = 24st 1.2lbs
- 155kg = 24st 6.2lbs
When using the stone and pounds conversion, remember that one stone always equals 14 pounds. This makes it easy to calculate intermediate values if needed.

Health Context — 150kg at Different UK Heights
At 150kg, your BMI depends on your height. For example, at an average UK male height of 175cm (5ft 9in), a weight of 150kg gives a BMI of approximately 49, which falls in the severely obese category (Class III). At 163cm (5ft 4in, average UK female height), the BMI would be around 56, also severely obese.
According to NHS guidelines, a healthy weight range at these heights would be significantly lower. If you'd like to understand your personal health context better, use our free BMI calculator above to enter your exact height and weight. Your GP can also provide tailored guidance about what your current weight means for your individual health and any next steps you might want to explore.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 150kg to stone without a calculator?
Divide 150 by 6.35 (a simplified version of 6.35029). This gives approximately 23.6 stone. To convert the decimal to pounds, multiply the decimal part (0.6) by 14, which gives about 8.4 pounds. So 150kg ≈ 23st 8lbs. For exact conversions, use our free weight converter above.
Is 150kg considered obese in the UK?
Whether 150kg is obese depends on your height. BMI categories range from overweight (25–29.9) to severely obese (40+). At most adult heights, 150kg would fall into the obese or severely obese range. Use our BMI calculator to check your personal BMI and get NHS-aligned category information.
What is the healthy weight range for someone who currently weighs 150kg?
The healthy weight range varies by height. For example, at 175cm (5ft 9in), a healthy weight is roughly 55–75kg (8st 10lbs to 11st 11lbs). At 163cm (5ft 4in), it's approximately 49–66kg (7st 9lbs to 10st 5lbs). Your GP can advise on realistic targets for your specific circumstances.
Can I lose weight from 150kg safely?
Yes. The NHS recommends sustainable weight loss of 0.5–1kg per week through a combination of dietary changes and increased physical activity. Losing even 5–10% of your body weight (7.5–15kg) can have meaningful health benefits. Your GP can discuss personalised approaches and whether any weight management support would help.
What's the difference between stone, pounds, and kilograms?
Stone, pounds, and kilograms are all weight measurements. In the UK, stone and pounds are traditional; 1 stone = 14 pounds. Kilograms (metric) are used internationally and in clinical settings. To convert: 1kg = 2.20462 pounds, and 1 stone = 6.35029kg. Our weight converter makes switching between them instant.
