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.
How to convert 72.9 kg to pounds
To convert 72.9 kg to lbs, use the standard kilogram to stone conversion formula: multiply kilograms by 2.20462.

This formula works for any weight. For context, here are nearby values showing the metric to imperial weight conversion pattern:
- 70 kg = 154.3 lbs
- 71 kg = 156.5 lbs
- 72 kg = 158.7 lbs
- 72.9 kg = 160.7 lbs
- 73 kg = 160.9 lbs

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 72.9 kg to stones and pounds?
72.9 kg converts to 11 stone 6.7 lbs using the standard conversion formula. Divide kg by 6.35029 to get stones. 72.9 ÷ 6.35029 = 11.48 stone, which is 11 stone plus 0.48 × 14 (7 lbs) = 11 stone 6.7 lbs.
Is 160.7 pounds considered a healthy weight?
Healthy weight depends on height, not absolute numbers. At 5ft 8in, 160.7 lbs gives a BMI of 24.4 (healthy). At 5ft 4in, it gives a BMI of 27.3 (overweight). Use the free BMI calculator on this page to check your personal BMI with your own height.
What's the difference between kg and lbs?
Kilograms (kg) are metric units used by the NHS and globally. Pounds (lbs) are imperial units traditionally used in the UK for body weight. One kilogram equals 2.20462 pounds. The UK also uses stones (14 lbs = 1 stone) for everyday weight discussions.
Why do UK health services use both kg and lbs?
The NHS primarily uses kilograms for clinical measurements and medical records. However, many UK adults think about their weight in stones and pounds because it's traditional in British culture. Both systems are correct — they're just different measurements of the same thing.
Can I use an online converter instead of calculating manually?
Yes. The weight converter tool on this page converts 72.9 kg to lbs, stone, and pounds instantly. Online converters are quick and accurate. However, knowing the conversion formula (kg × 2.20462 = lbs) is useful if you ever need to convert without a calculator.
