What Is 79.5kg in Lbs and What's Your BMI?
79.5kg is equal to 175.2 pounds. However, your BMI—which is what really matters for health—depends entirely on your height. At different heights, 79.5kg can range from overweight to obese according to NHS guidelines. Use our free BMI calculator above to find out your exact BMI, or read on to see where 79.5kg falls for common UK heights using the standard kg to stone and pounds conversion.

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.
BMI at 79.5kg — Examples Across Different Heights
79.5kg (175.2 lbs) gives very different BMI values depending on how tall you are. Here are examples for typical UK heights:
- At 5ft 4in (163cm): BMI = 30.2 (Obese Class I)
- At 5ft 6in (168cm): BMI = 28.1 (Overweight)
- At 5ft 8in (173cm): BMI = 26.6 (Overweight)
- At 5ft 10in (178cm): BMI = 25.1 (Healthy weight)
- At 6ft (183cm): BMI = 23.7 (Healthy weight)
- At 6ft 2in (188cm): BMI = 22.5 (Healthy weight)
As you can see, the same weight produces very different health classifications based on height. This is why BMI matters more than the raw kilogram or pound figure alone.

Understanding Your BMI Category
According to NHS guidelines, healthy BMI ranges from 18.5 to 24.9. If your BMI at 79.5kg falls outside this range, it doesn't mean you're unhealthy—it's simply a screening tool to flag potential health risks. BMI has limitations: it doesn't distinguish between muscle and fat, and doesn't account for where fat is stored (waist measurement also matters). For people of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower thresholds: 18.5–22.9 is healthy, and 23.0–27.4 is overweight. Your GP can provide personalised advice about what your specific BMI means for your health.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 79.5kg overweight or obese?
It depends on your height. At 5ft 6in, 79.5kg gives a BMI of 28.1 (overweight). At 5ft 4in, it's 30.2 (obese). At 5ft 10in, it's 25.1 (healthy weight). Use our free BMI calculator above to find your exact category based on your height.
How do I convert 79.5kg to stones and pounds?
79.5kg equals 12 stone 8.3 lbs (or approximately 12st 8lbs). To convert, divide 79.5 by 6.35029 to get stone, then multiply the decimal by 14 to get pounds. Our weight converter tool above makes this instant.
What's a healthy weight for my height?
A healthy BMI is 18.5–24.9 according to NHS guidelines. Calculate your ideal weight range using the BMI calculator on this page by entering your height—it will show you the weight range for healthy BMI at your specific height.
Why does BMI differ so much by height?
BMI accounts for how weight is distributed across your body. Taller people can carry more weight while maintaining the same BMI as shorter people. This is why two people weighing 79.5kg can have completely different health classifications.
Should I lose weight if my BMI is overweight?
That depends on your individual health, not just BMI. Your GP can assess your overall health picture, including waist measurement, blood pressure, and family history. Even modest weight loss (5–10%) can improve health outcomes. Our free progress tracker can help you log any changes.
