What BMI Is 70kg? Weight Guide for UK Adults
If you weigh 70kg, your BMI depends entirely on your height—there's no single answer. At 70kg, you could be anywhere from underweight to overweight depending on how tall you are. Use our free BMI calculator above to find your exact BMI, then see where it falls on the NHS scale. We've included example BMI values at different heights so you can see how 70kg translates to stone and pounds, and what it means for your health.

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.
70kg BMI at Different Heights
70kg equals approximately 154.3 pounds or 11 stone. Here's what your BMI would be at common heights using the standard BMI formula—and which NHS category each falls into:
- At 160cm (5ft 3in): BMI of 27.3 = Overweight (NHS category)
- At 165cm (5ft 5in): BMI of 25.7 = Overweight
- At 170cm (5ft 7in): BMI of 24.2 = Healthy weight
- At 175cm (5ft 9in): BMI of 22.9 = Healthy weight
- At 180cm (5ft 11in): BMI of 21.6 = Healthy weight
- At 185cm (6ft 1in): BMI of 20.4 = Healthy weight
As you can see, 70kg is a healthy weight for taller adults but may be in the overweight range if you're shorter. The weight converter and BMI calculator on this page help you check your exact position instantly.

NHS BMI Categories & Important Limitations
The NHS defines healthy BMI as 18.5 to 24.9. Overweight is 25.0–29.9, and obese starts at 30.0 or above. However, BMI has important limitations: it doesn't distinguish between muscle and fat, so athletes may have a high BMI but low body fat. It also doesn't account for where fat is stored—waist circumference matters too. For adults of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds due to higher health risks at the same BMI. Your GP can give you personalised advice about what your weight means for your individual health.
