What Is 79 Kg In Stones And Pounds?
79 kilograms is equivalent to 12 stone and 5.3 pounds (or 174.2 lbs). However, whether this weight is healthy depends entirely on your height — the same weight can give a very different BMI for different individuals. Use our free BMI calculator above to find your personal BMI, or check the height-specific examples below to see where you fall on the NHS health categories.

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.
79 Kg BMI At Different Heights
To understand what 79kg means for your health, you need to calculate your BMI using both weight and height. Here's how 79kg converts to different BMI values at common UK heights:
- At 160cm (5ft 3in): BMI 30.9 — falls in the obese category
- At 165cm (5ft 5in): BMI 29.0 — falls in the overweight category
- At 170cm (5ft 7in): BMI 27.3 — falls in the overweight category
- At 173cm (5ft 8in): BMI 26.4 — falls in the overweight category
- At 178cm (5ft 10in): BMI 24.9 — falls in the healthy weight range
- At 183cm (6ft 0in): BMI 23.6 — falls in the healthy weight range
To calculate your exact BMI at 79kg, use the weight converter and BMI calculator on this page by entering your height. Individual health risk depends on multiple factors including age, fitness level, and family history, so speak to your GP for personalised advice.

NHS BMI Categories & Health Context
The NHS defines healthy BMI as 18.5 to 24.9 for most UK adults. If you fall into the overweight or obese range, even a modest weight loss of 5–10% can improve blood pressure, blood sugar control, and cholesterol levels. At 79kg, reaching a healthy BMI would typically require a weight loss of 5–15kg depending on your height — your GP or a specialist weight management service can advise on safe, sustainable approaches. Remember that BMI is a screening tool only and doesn't account for muscle mass or where fat is stored, so discuss your individual context with a healthcare professional.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 79kg overweight?
This depends on your height. At 79kg, you could have a healthy BMI (if you're tall — over 178cm), overweight (165–178cm), or obese (under 160cm) according to NHS categories. Use the BMI calculator above with your height to find out where you personally sit.
What does 79kg equal in stone and pounds?
79 kilograms equals 12 stone and 5.3 pounds (174.2 lbs total). To convert kilograms to stone, divide by 6.35029 — this standard metric to imperial weight conversion applies across all kg to stone conversions.
How much weight would I need to lose from 79kg to reach a healthy BMI?
This varies by height. Someone 165cm tall would need to lose around 5–7kg to reach BMI 25. Someone 160cm would need to lose 12–15kg. Use our free BMI calculator to enter your height and see your personal healthy weight range.
Can I use BMI alone to assess my health at 79kg?
BMI is a useful screening tool but has limitations — it doesn't distinguish between muscle and fat, and doesn't account for where body fat is stored. Waist circumference and overall fitness also matter. Your GP can give personalised health advice beyond BMI alone.
Should I aim to lose weight if I'm 79kg?
This depends on your height, age, fitness level, and any health conditions. If your BMI falls in the overweight or obese range, your GP may recommend gradual, sustainable weight loss. Track your progress with our free progress tracker and discuss your goals with your healthcare provider.
