79 Kilos in Stones and Pounds
79 kilograms is equal to 12 stone and 6.5 pounds (12st 6.5lbs). If you need to convert kilograms to stone using the standard conversion formula, simply divide the kilogram value by 6.35 to get stone. This weight falls into the overweight category for most UK adults according to NHS guidelines, though your personal BMI depends on your height. Use our free BMI calculator above to find your exact BMI and see whether this weight is healthy for your specific height.

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.
79kg to Stone Conversion — Exact Formula and Table
To convert 79 kilos to stone and pounds, use this simple formula: divide kilograms by 6.35 to get stone. For 79kg, this gives 12.45 stone, which breaks down as 12 stone and 6.5 pounds. You can also use the reverse calculation—multiply stone by 6.35 to convert back to kilograms.
Here's a handy reference table showing 79kg alongside nearby weights in both metric to imperial weight conversions:
- 75kg = 11st 11lbs
- 76kg = 11st 13.5lbs
- 77kg = 12st 1.5lbs
- 78kg = 12st 3.5lbs
- 79kg = 12st 6.5lbs
- 80kg = 12st 8lbs
- 81kg = 12st 9.5lbs
- 82kg = 12st 11.5lbs
- 83kg = 13st 1lbs

79kg BMI and Healthy Weight Context
At 79kg, your BMI depends entirely on your height. For example, at the average UK female height of 163cm (5ft 4in), 79kg gives a BMI of 29.7 (overweight category). At the average UK male height of 175cm (5ft 9in), 79kg gives a BMI of 25.8 (healthy weight category). The NHS defines healthy weight as a BMI between 18.5 and 24.9, though ethnicity-adjusted thresholds are lower for South Asian, Chinese, Black African, and Black Caribbean adults. To understand what 79kg means for your personal health, calculate your individual BMI using the free calculator on this page. If you're concerned about your weight, your GP can provide personalised advice about healthy weight ranges for your age, sex, and medical history.
