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 by Height
To convert kilograms to stone, 58.8 kg equals approximately 9 stone 4 lbs. Whether this weight is healthy depends on your height. The NHS uses BMI (body mass index) as the standard screening tool to determine healthy weight ranges.
- At 5ft 2in (157 cm): 58.8 kg gives a BMI of 23.9 — this is in the healthy weight range (18.5–24.9)
- At 5ft 4in (163 cm): 58.8 kg gives a BMI of 22.1 — healthy weight range
- At 5ft 0in (152 cm): 58.8 kg gives a BMI of 25.5 — this falls in the overweight range (25–29.9)
The healthy weight range for any height depends on the formula: BMI = weight (kg) ÷ height (m)². A healthy BMI sits between 18.5 and 24.9 according to NHS guidelines.

What to Do if Your Weight Is Outside the Healthy Range
If you've calculated that 58.8 kg puts you outside the healthy range for your height, the NHS recommends a non-judgmental approach: small, sustainable changes to diet and physical activity often make the biggest difference. Aim for a weight loss of 0.5–1 kg per week if you're overweight, achieved through a modest calorie deficit.
It's also worth measuring your waist circumference — excess weight around the middle poses additional health risks. For men, a waist over 94 cm (37 inches) indicates increased risk; for women, over 80 cm (31.5 inches). Your GP can provide personalised guidance about what your weight means for your individual health and recommend support if needed.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 58.8 kg in stone and pounds?
58.8 kg equals 9 stone and 4 pounds (or 9st 4lbs). To convert kilogram to stone conversion, divide kilograms by 6.35: 58.8 ÷ 6.35 = 9.26 stone. Use our free weight converter on this page for instant conversions between kg, stone, and pounds.
Is 58.8 kg a healthy weight for an adult?
It depends on your height. At average heights (5ft 2in to 5ft 6in), 58.8 kg typically falls in the healthy weight range. Use our BMI calculator above to check your personal result. If you're shorter (under 5ft), this weight might be overweight; if you're taller (over 5ft 8in), it's likely healthy.
What's the healthy weight range for my height?
Healthy weight ranges from a BMI of 18.5 to 24.9. For example, at 5ft 4in (163 cm), the healthy weight range is approximately 47–62 kg (7st 6lbs to 9st 10lbs). At 5ft 8in (173 cm), it's 55–75 kg (8st 8lbs to 11st 10lbs). Calculate your personal range using our free BMI calculator.
Should I aim to lose weight at 58.8 kg?
Only if your BMI is above 24.9 or your GP recommends it. Weight alone doesn't determine health — your height, muscle mass, and where weight is distributed all matter. Consider your waist measurement too: for men over 94 cm or women over 80 cm, even at a healthy BMI, health risks increase. Speak with your GP for personalised advice.
How quickly should I lose weight if I'm overweight?
The NHS recommends losing no more than 0.5–1 kg (1–2 lbs) per week for sustainable, healthy weight loss. This typically requires a calorie deficit of around 500 kcal per day. Faster weight loss can lead to muscle loss and is harder to maintain. Your GP or a registered dietitian can help create a personalised plan.
