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.
BMI at Different Heights for 148 lbs (67.1 kg)
At 148 lbs (67.1 kg), your BMI varies significantly depending on your height. Here's how this weight converts to BMI across common UK heights:
- 5ft 2in (157 cm) — BMI 27.3 (Overweight)
- 5ft 5in (165 cm) — BMI 25.2 (Overweight)
- 5ft 8in (173 cm) — BMI 23.4 (Healthy weight)
- 5ft 10in (178 cm) — BMI 22.0 (Healthy weight)
- 6ft 0in (183 cm) — BMI 20.7 (Healthy weight)
- 6ft 3in (190 cm) — BMI 19.6 (Healthy weight)
To accurately convert kilograms to BMI, you need both your weight in kg and your height in metres. Our weight converter makes it easy to switch between imperial and metric units, and the BMI calculator on this page will give you your personal category instantly.

NHS BMI Categories and Weight Health Guidance
The NHS divides BMI into clear categories to help adults understand their weight health status. A BMI under 18.5 is underweight, 18.5 to 24.9 is healthy weight, 25 to 29.9 is overweight, and 30 or above falls into obesity categories. At 148 lbs (67.1 kg), whether you're in the overweight or healthy range depends on your height, as shown above. Remember that BMI has limitations — it doesn't distinguish between muscle and fat, so athletes or very muscular individuals may have a high BMI despite low body fat. Your GP can provide personalised advice about what your BMI means for your individual health.
