10.7 Kg In Stone — What's Your BMI?
10.7 kg converts to approximately 1 stone 8.5 pounds (1st 8.5lbs). However, your BMI — the key health measure — depends entirely on your height. The same weight of 10.7 kg can give you a healthy BMI at one height but indicate overweight status at another. This guide shows your BMI at different heights using NHS standards, helps you understand where you sit on the NHS weight categories, and explains what this means for your health. Use our free BMI calculator above to instantly check your personal BMI.

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 — 10.7 Kg
A weight of 10.7 kg is exceptionally light for most UK adults — this weight is typically seen only in infants or very young children. For reference, here's how it converts and what BMI it produces at various adult heights:
- At 1.50m (4ft 11in): BMI of 4.8 — far below the healthy range (18.5–24.9)
- At 1.60m (5ft 3in): BMI of 4.2 — severely underweight by any standard
- At 1.70m (5ft 7in): BMI of 3.7 — critically low
- At 1.80m (5ft 11in): BMI of 3.3 — critically low
If you're an adult weighing 10.7 kg, this indicates a serious medical condition requiring urgent GP assessment. For children, use age-specific growth charts rather than adult BMI categories. Convert kilograms to stone using our free weight converter for other weights.

NHS BMI Categories & Health Context
The NHS defines healthy BMI as 18.5–24.9 for most UK adults, and lower thresholds for people of South Asian, Chinese, Black African, or Black Caribbean heritage (18.5–22.9). BMI is calculated by dividing weight in kg by height in metres squared. While useful as a screening tool, BMI has limitations — it doesn't distinguish between muscle and fat, and doesn't account for where fat is stored. Waist circumference is equally important. If you're concerned about your weight in stone and pounds or your health status, speak to your GP for personalised advice and proper assessment.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 10.7 kg in stone and pounds?
10.7 kg converts to approximately 1 stone 8.5 pounds (written as 1st 8.5lbs). To convert kilograms to stone, divide by 6.35. This is an exceptionally light weight for an adult and would indicate a serious medical concern requiring GP assessment.
Is 10.7 kg a healthy weight for an adult?
No. 10.7 kg is far below healthy weight for any adult, regardless of height. Healthy adult weights typically start around 45–55 kg depending on height. If you're at or near this weight, please contact your GP immediately for medical evaluation.
What BMI does 10.7 kg give at average UK heights?
At typical UK adult heights (1.60–1.80m), a weight of 10.7 kg produces a BMI between 3.3 and 4.2 — all critically low and far below the healthy range of 18.5–24.9. This requires urgent medical attention.
Is 10.7 kg appropriate for children?
10.7 kg is a normal weight for children aged approximately 2–3 years old. Children's weight assessment uses age and sex-specific growth charts (UK90 references), not adult BMI categories. If you have concerns about a child's weight, ask your health visitor or GP.
