Is 150kg a Healthy Weight? Convert to Stone and Check Your Health Range
150kg converts to 23 stone and 8 pounds (approximately 330 lbs). Whether this weight is healthy depends entirely on your height. At 150kg, an adult could have a BMI ranging from just under 18 (underweight) to well over 40 (severely obese), depending on how tall they are. This guide shows you how to find out if 150kg is a healthy weight for you personally, with concrete examples for different heights and NHS guidance on what to do if you're outside the healthy range. Use our free BMI calculator above to check your specific BMI instantly.

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.
What's a Healthy Weight at 150kg? Height-Based Examples
At 150kg, your healthy weight status depends entirely on your height. Here are three real-world examples:
- Someone 6ft 4in (193cm): 150kg gives a BMI of 25.6 — overweight but close to the healthy range (18.5–24.9). Only 2–3kg loss would reach healthy weight.
- Someone 5ft 10in (178cm): 150kg gives a BMI of 31.1 — obese (Class I). Healthy range for this height is 57–76kg. Weight loss of 30–35kg would reach the lower healthy threshold.
- Someone 5ft 4in (163cm): 150kg gives a BMI of 40.2 — severely obese (Class III). Healthy range is 49–66kg. This person would need to lose over 80kg to reach a healthy weight range.
These examples show why height is everything — the same weight can be healthy, overweight, or obese depending on how tall you are. Use our weight converter to check kilos to stone conversions, and our BMI calculator to find your personal healthy weight range instantly.

NHS Healthy Weight Guidance and What to Do Next
NHS BMI categories for adults: A healthy BMI is 18.5–24.9. At 150kg, check your BMI using your height — if it's above 25, you're outside the healthy range.
Waist measurement also matters: men should aim for under 94cm (37in), women under 80cm (31.5in). If you're carrying excess weight, even a 5% loss has meaningful health benefits — that's just 7.5kg from 150kg, which can improve blood pressure, blood sugar, and joint health.
If you're concerned about your weight, your GP can give personalised advice. For sustainable weight loss, the NHS recommends 0.5–1kg per week through calorie reduction and physical activity. Track your progress with our free progress tracker to stay motivated.
