What is 67 Kilos in Stones?
67 kilos equals approximately 10 stone 8.2 pounds (10st 8lbs) in UK measurements. However, your BMI — which determines whether this weight is healthy for you — depends entirely on your height. At different heights, 67kg produces very different health outcomes according to NHS guidelines. Use our free BMI calculator above to find your personal BMI, or read on to see examples at common UK heights.

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.
67kg BMI at Different Heights
To convert kilograms to stone, divide by 6.35 — so 67kg ÷ 6.35 = 10st 8lbs. But this weight gives different BMI values depending on your height:
- At 160cm (5ft 3in): BMI = 26.1 (Overweight)
- At 165cm (5ft 5in): BMI = 24.6 (Healthy weight)
- At 170cm (5ft 7in): BMI = 23.2 (Healthy weight)
- At 175cm (5ft 9in): BMI = 21.8 (Healthy weight)
- At 180cm (5ft 11in): BMI = 20.6 (Healthy weight)
- At 185cm (6ft 1in): BMI = 19.6 (Healthy weight)
The same weight in stone and lbs can be perfectly healthy for a taller person but overweight for someone shorter. This is why height matters so much in health assessment.

NHS BMI Categories & What They Mean
According to NHS guidelines, a healthy BMI range is 18.5 to 24.9 for most UK adults. At 67kg, you fall into the healthy weight category if you're taller than about 163cm (5ft 4in). For South Asian, Chinese, Black African, or Black Caribbean adults, the NHS recommends lower thresholds — a healthy BMI starts at 18.5 and ends at 22.9. Remember: BMI is a useful screening tool but has limitations — it doesn't account for muscle mass, where fat is stored, or individual fitness levels. Your GP can provide personalised advice about what your BMI means for your specific health.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 67kg in stone and pounds?
67kg equals 10 stone 8.2 pounds (10st 8lbs). To convert kilograms to stone manually, divide the kg by 6.35. Use our free weight converter above for instant conversions between all UK and metric measurements.
Is 67kg a healthy weight?
It depends on your height. At 165cm or taller, 67kg typically falls in the healthy weight range according to NHS guidelines. At shorter heights, it may be classified as overweight. Use our free BMI calculator above to check your personal BMI based on your exact height.
What BMI is 67kg at 170cm?
At 170cm, a weight of 67kg gives a BMI of 23.2, which falls in the healthy weight category (18.5–24.9) according to NHS guidelines. This is a good health outcome for most adults.
Do ethnicity-adjusted BMI thresholds apply to 67kg?
Yes. For South Asian, Chinese, Black African, or Black Caribbean adults, the NHS recommends lower BMI thresholds. At 67kg and 170cm, the BMI is still 23.2, which is healthy under both standard and ethnicity-adjusted guidelines.
How accurate is BMI as a health measure?
BMI is useful for screening but has limitations. It doesn't distinguish between muscle and fat — athletes may have high BMI but low body fat. Waist circumference and overall fitness matter too. Your GP can give you personalised health advice beyond BMI alone.
