247 Lbs to Kg — What's Your BMI?
247 pounds is approximately 112 kilograms. However, your BMI — which is the most useful measure for understanding whether this weight is healthy — depends entirely on your height. Someone who is 5ft 4in (163cm) will have a very different BMI than someone who is 6ft 2in (188cm), even though they weigh the same. To find out what your BMI is at 247 lbs and where it sits on the NHS health scale, use our free BMI calculator above, or read on for examples at common heights.

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.
247 Lbs in Kg at Different Heights — BMI Results
247 lbs converts to approximately 112 kilograms using the standard metric to imperial weight conversion. Your BMI at this weight depends on your height. Here are examples:
- At 5ft 4in (163cm): BMI of 36.8 — Obese (Class II)
- At 5ft 8in (173cm): BMI of 34.3 — Obese (Class I)
- At 5ft 10in (178cm): BMI of 31.6 — Obese (Class I)
- At 6ft 0in (183cm): BMI of 29.3 — Overweight
- At 6ft 2in (188cm): BMI of 27.5 — Overweight
- At 6ft 4in (193cm): BMI of 25.9 — Healthy weight
These figures show how the same weight can fall into different NHS health categories depending on your height. Your GP can discuss what your BMI means for your individual health.

Understanding BMI Categories & Limitations
The NHS uses five BMI categories: Healthy weight (18.5–24.9), Overweight (25–29.9), Obese Class I (30–34.9), Obese Class II (35–39.9), and Severely Obese (40+). While BMI is a useful screening tool, it has important limitations — it doesn't distinguish between muscle and fat, doesn't account for where fat is stored (waist measurement matters too), and may be less accurate for athletes or elderly people. For people of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds due to higher health risks at the same BMI.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 247 lbs to kg exactly?
Multiply 247 by 0.453592. This equals 112.04 kg. For practical purposes, 247 lbs = 112 kg. You can also use our free weight converter on this page to convert between lbs, kg, and stone instantly.
What BMI should I aim for according to the NHS?
The NHS recommends a BMI between 18.5 and 24.9 for most UK adults. If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, aim for 18.5 to 22.9. Use the BMI calculator above to check your personal BMI at your current height and weight.
Is 247 pounds considered overweight or obese?
It depends on your height. At 247 lbs, most adults would fall into the Overweight or Obese categories according to NHS guidelines. However, someone very tall (6ft 4in+) could have a healthy BMI at this weight. Calculate your specific BMI using the tool on this page.
What's the difference between BMI categories?
NHS categories are: Healthy weight (BMI 18.5–24.9), Overweight (25–29.9), Obese Class I (30–34.9), Obese Class II (35–39.9), and Severely Obese (40+). Each category reflects increasing health risk, though BMI has limitations and doesn't account for muscle mass or body composition.
Should I lose weight if I'm at 247 lbs?
Whether weight loss is recommended depends on your height, overall health, and any weight-related health conditions. Your GP can assess your individual situation and discuss whether losing weight would benefit your health. Even a 5–10% reduction in body weight can improve health markers like blood pressure and blood sugar.
