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.

Is 117 Lbs a Healthy Weight?
Whether 117 lbs (53.07 kg) is a healthy weight depends on your height. At an average UK female height of 5ft 3in (160 cm), a weight of 117 lbs gives a BMI of approximately 20.8—which falls comfortably in the healthy weight range of 18.5 to 24.9 according to NHS guidelines. However, at taller or shorter heights, this weight would fall into different BMI categories. Use our free BMI calculator above to check your personal BMI based on your exact height and weight. Even within a healthy BMI range, factors like fitness level, muscle mass, and waist circumference also matter for overall health. Your GP can provide personalised guidance on whether your weight is right for you.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 117 pounds to kilograms quickly?
Multiply 117 by 0.453592. The result is 53.07 kg. Our free weight converter tool on this page does this automatically—just enter your weight and select the units you want to convert between.
What is 117 lbs in stone and pounds?
117 lbs equals 8 stone 5 pounds. To convert lbs to stone, divide by 14 (since 1 stone = 14 pounds). This is the standard UK measurement format used on NHS weight charts and by GPs.
Is 117 pounds overweight for an average adult?
It depends on height. At 5ft 3in, 117 lbs is a healthy weight (BMI ~20.8). At 5ft 10in, it would be underweight (BMI ~16.8). Use our BMI calculator to check your specific BMI based on your height.
Why do UK measurements use stone and pounds?
Stone and pounds are traditional imperial units still widely used in the UK for body weight, even though kilograms are used in clinical settings. NHS charts often show both units so patients can relate to familiar measurements.
Can I use this conversion for baby weight or children?
Yes, the kg to pounds conversion formula works for any weight. However, for assessing whether a child's weight is healthy, use age and sex-specific growth charts (UK90 charts) rather than adult BMI categories, as children's healthy weight ranges differ significantly.
