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.

The exact conversion from 122 lbs to kilograms is 55.33 kg. To calculate this yourself, multiply your weight in pounds by 0.453592. The reverse calculation works too: divide kilograms by 0.453592 to get pounds.

BMI & Healthy Weight At 122 Lbs
At 122 lbs (55.3 kg), your BMI depends on your height. For an adult who is 5ft 5in (165 cm), a weight of 122 lbs gives a BMI of approximately 20.3, which falls in the healthy weight range according to NHS guidelines (18.5 to 24.9). However, if you're taller or shorter, your BMI will differ.
You can calculate your personal BMI instantly using our free BMI calculator above, which takes your exact height into account. The NHS also recommends considering waist circumference alongside BMI, as where fat is stored matters for health.
