9.7 Stone in Pounds — Healthy Weight Guide
9.7 stone is equivalent to 135.8 pounds, or approximately 61.2 kilograms. But whether this weight is healthy depends entirely on your height. For some adults, 9.7 stone is a perfectly healthy weight; for others, it may fall outside the recommended range. This guide shows you how to check if 9.7 stone is right for you, with practical examples at different heights and NHS guidance to help you understand your personal healthy weight range.

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.
Healthy Weight Ranges at Different Heights
Whether 9.7 stone (135.8 lbs or 61.2 kg) is healthy depends on your height. The NHS uses BMI as a screening tool — a healthy BMI sits between 18.5 and 24.9. To check if 9.7 stone is healthy for you, you need to know your height. Use our free BMI calculator above to enter your height and weight instantly.
Example 1: At 5ft 2in (157cm) — 9.7 stone gives a BMI of 25.1, which falls into the overweight category. A healthy weight range at this height would be 7st 7lbs to 9st 10lbs (47–62 kg).
Example 2: At 5ft 6in (168cm) — 9.7 stone gives a BMI of 22.1, which is solidly in the healthy range. The healthy weight range at this height is roughly 8st 3lbs to 11st (52–70 kg).
Example 3: At 5ft 10in (178cm) — 9.7 stone gives a BMI of 20.4, which is well within the healthy range. The healthy weight range at this height is approximately 8st 13lbs to 11st 13lbs (57–76 kg).

NHS Guidance and What to Do Next
The NHS recommends a healthy BMI of 18.5–24.9 for most UK adults. For people of South Asian, Chinese, Black African, or Black Caribbean heritage, healthier BMI thresholds are slightly lower (18.5–22.9), as these groups face higher health risks at the same weight. Beyond BMI, waist circumference matters too: men should aim for under 94cm (37 inches), and women under 80cm (31.5 inches).
If 9.7 stone falls outside your healthy range for your height, the NHS recommends gradual weight changes of 0.5–1 kg (1–2 lbs) per week. This can be achieved through a modest calorie deficit combined with regular physical activity. If you're unsure whether your current weight is healthy, book an appointment with your GP for personalised advice — they can assess your individual health context, not just the numbers on the scale.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 9.7 stone in kilograms?
9.7 stone equals approximately 61.2 kilograms. To convert stone to kg, multiply by 6.35029. So 9.7 × 6.35029 = 61.2 kg. You can use our weight converter above to switch between stone, pounds, and kilograms instantly.
How do I know if 9.7 stone is healthy for me?
Your height determines whether 9.7 stone is healthy. Use our free BMI calculator to enter your weight and height — it will tell you whether 9.7 stone falls in the healthy, overweight, or obese range for you. A healthy BMI is 18.5–24.9 according to NHS guidelines.
What is the healthy weight range for my height?
The healthy weight range varies by height. At 5ft 6in, the healthy range is roughly 8st 3lbs to 11st. At 5ft 10in, it's about 8st 13lbs to 11st 13lbs. For your exact height, use our BMI calculator above to see the specific healthy weight range in stone, pounds, and kg.
Is waist measurement important alongside weight?
Yes. The NHS recommends measuring waist circumference in addition to weight. For men, under 94cm (37 inches) is healthier; for women, under 80cm (31.5 inches). Waist measurement helps assess where fat is stored, which affects health risk independent of BMI.
What should I do if my weight is outside the healthy range?
If 9.7 stone is outside your healthy range, the NHS recommends aiming for gradual weight change of 0.5–1 kg per week through a balanced diet and physical activity. Speak to your GP for personalised advice — they can assess your individual health, medical history, and any underlying conditions affecting your weight.
