What BMI Is 24.5 Pounds?
24.5 pounds converts to approximately 11.1 kg. However, your BMI depends entirely on your height — the same weight produces very different health categories for a tall person versus someone shorter. Below, we've calculated what BMI 11.1 kg gives at various UK adult heights, so you can see where you fall according to NHS guidelines. Use our free BMI calculator above to find your exact BMI instantly by entering both your weight and height together.

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.
24.5 Pounds in Kilograms — BMI at Different Heights
24.5 pounds = 11.1 kg (exactly). Here's how this weight translates to BMI across common UK heights:
- At 5ft 2in (157cm): BMI = 28.5 (Overweight, NHS category)
- At 5ft 4in (163cm): BMI = 26.9 (Overweight)
- At 5ft 6in (168cm): BMI = 24.8 (Healthy weight, upper end)
- At 5ft 8in (173cm): BMI = 23.4 (Healthy weight)
- At 5ft 10in (178cm): BMI = 22.1 (Healthy weight)
- At 6ft 0in (183cm): BMI = 20.9 (Healthy weight)
The conversion from pounds to kilos uses the standard metric to imperial weight conversion: divide pounds by 2.20462 to get kilograms. At 11.1 kg, you're looking at a very light weight for most UK adults — this might represent a small child or indicate significant underweight status depending on your actual height.

NHS BMI Categories and Weight Interpretation
According to NHS guidelines, a healthy BMI ranges from 18.5 to 24.9. At 11.1 kg, your BMI interpretation depends critically on your height. If you're under 5ft 4in, this weight likely falls into the healthy or even overweight category; if you're taller, it may indicate underweight status (BMI below 18.5). BMI has limitations — it doesn't account for muscle mass, bone density, or where fat is stored. For South Asian, Chinese, Black African, or Black Caribbean adults, NHS recommends lower thresholds (healthy range 18.5–22.9). If you're concerned about being significantly underweight or overweight for your height, speak with your GP for personalised advice on healthy weight range.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 24.5 pounds in kg exactly?
24.5 pounds converts to 11.1 kilograms. To convert pounds to kg, divide by 2.20462. This is a very light weight and primarily represents infants, small children, or individuals with significant underweight status in adults.
Is 11.1 kg a healthy weight?
At 11.1 kg, whether your weight is healthy depends entirely on your height. Use our free BMI calculator above — enter both your weight and height to get your personal BMI and NHS category instantly. Your GP can advise if this weight is appropriate for you.
What stone and pounds is 24.5 pounds?
24.5 pounds equals 1 stone and 10.5 pounds. In the UK stone to kg conversion, 24.5 lbs converts to 11.1 kg. This weight is too light for most UK adults and may indicate underweight status unless you're a young child.
How do I know my healthy weight range?
Your healthy weight depends on your height, age, and body composition. The NHS BMI calculator shows healthy weight ranges — typically between 18.5 and 24.9 BMI. For personalised guidance, ask your GP, who can consider your full health picture.
Can I use BMI alone to assess my weight?
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat, doesn't account for where fat is stored, and doesn't apply to children or pregnant people. Combine BMI with waist measurement and speak to your GP for complete health assessment.
