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.
68.4 Kg BMI at Different Heights
At 68.4 kg (150.8 pounds), your BMI varies significantly by height. Here are examples at typical UK adult heights:
- 5ft 2in (157 cm): BMI 27.7 — Overweight (NHS category)
- 5ft 4in (163 cm): BMI 25.5 — Overweight
- 5ft 6in (168 cm): BMI 23.6 — Healthy weight
- 5ft 8in (173 cm): BMI 22.0 — Healthy weight
- 5ft 10in (178 cm): BMI 20.6 — Healthy weight
- 6ft 0in (183 cm): BMI 19.4 — Healthy weight
These examples show how height dramatically affects BMI classification. Shorter adults at 68.4 kg may be in the overweight range, while taller adults fall comfortably into the healthy weight range. The NHS recommends a healthy BMI between 18.5 and 24.9 for most adults. Your GP can help you understand what your personal BMI means for your health.

Understanding BMI Categories and Limitations
The NHS BMI categories are: under 18.5 (underweight), 18.5–24.9 (healthy weight), 25.0–29.9 (overweight), 30.0+ (obese). However, BMI has important limitations — it doesn't distinguish between muscle and fat, so athletes may have higher BMI despite low body fat. For South Asian, Chinese, Black African, or Black Caribbean adults, the NHS recommends lower thresholds: healthy weight is 18.5–22.9, overweight starts at 23.0. Waist circumference matters too: over 80 cm (31.5in) for women or 94 cm (37in) for men indicates increased health risk.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 68.4 kg in stone and pounds?
68.4 kg equals 10 stone 12.5 pounds (or approximately 10st 12lbs). To convert kilograms to stone, divide by 6.35. To convert kg to stone and pounds together, multiply kg by 0.157473 for stone, then use the decimal to calculate pounds (multiply by 14). Our weight converter on this page makes these calculations instant and accurate for metric to imperial conversions.
Is 68.4 kg a healthy weight?
Whether 68.4 kg is healthy depends on your height and individual health. At average UK heights (5ft 4in to 5ft 10in), this weight typically falls in the healthy or slightly overweight range. Your GP can assess your personal health status based on BMI, waist circumference, and other factors. Use our BMI calculator to see where you fall on the NHS scale.
How do I know if 68.4 kg is right for me?
Your ideal weight depends on your height, age, muscle mass, and medical history. The NHS healthy weight range for each height varies — for example, at 5ft 6in, healthy weight is roughly 7st 6lbs to 9st 5lbs (47–59 kg). Your GP can advise on a healthy target weight for you personally. Health is not just about weight — fitness, diet, and overall wellbeing matter too.
What does BMI stand for and how is it calculated?
BMI stands for Body Mass Index. It's calculated as weight (kg) divided by height in metres squared. BMI is a screening tool used by the NHS to identify potential health risks, but it has limitations. It doesn't account for muscle mass, bone density, or fat distribution. Waist measurement is also important for assessing health risk.
Can I use stone and pounds with the BMI calculator?
Yes — our free BMI calculator accepts weight in kg, stone, or pounds, and height in centimetres, metres, feet, or inches. Simply enter your measurements in whichever units you prefer, and the calculator gives you your BMI instantly along with your NHS health category. It's the easiest way to check where you stand.
