What Is 117 Kg in Stone and What's the BMI?
117 kilograms is equivalent to 18 stone 5.3 pounds (18st 5lbs). However, your BMI depends on your height — the same weight can be healthy for a tall person but overweight for someone shorter. Use our free BMI calculator above to find your personal BMI instantly, then check where you fall on the NHS health scale. This guide shows you the BMI range at different heights so you can understand what 117kg means for your health.

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.
117 Kg BMI at Different Heights
At 117kg, your BMI varies significantly depending on your height. Here's what 117 kilograms gives you at common UK heights, using the standard kg to stone conversion alongside BMI calculation:
- 5ft 0in (152cm): BMI 31.9 — Obese (Class I)
- 5ft 4in (163cm): BMI 27.5 — Overweight
- 5ft 8in (173cm): BMI 24.2 — Healthy weight
- 5ft 10in (178cm): BMI 22.6 — Healthy weight
- 6ft 0in (183cm): BMI 21.0 — Healthy weight
- 6ft 2in (188cm): BMI 19.7 — Healthy weight
As you can see, weight in stone alone doesn't determine health — height makes a critical difference. Calculate your exact BMI now using the calculator on this page to see your personal health category.

NHS BMI Categories and Health Context
The NHS divides adults into BMI categories: healthy weight (18.5–24.9), overweight (25.0–29.9), obese Class I (30.0–34.9), and severely obese (40.0+). At 117kg, whether you fall into these categories depends entirely on your height. If you're shorter, your BMI may indicate overweight or obesity; if you're taller, the same weight can be perfectly healthy. Remember that BMI has limitations — it doesn't account for muscle mass, so athletes may have a higher BMI without excess fat. Use our free weight converter to check 117kg in different units, and discuss your personal health goals with your GP, who can assess your individual circumstances beyond BMI alone.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 117 kg in stone and pounds?
117 kg equals 18 stone 5.3 pounds (or approximately 18st 5lbs). To convert kilograms to stone, divide by 6.35. So 117 ÷ 6.35 = 18.43 stone. The decimal converts to pounds: 0.43 × 14 = 6 pounds, giving you 18 stone 6 pounds as a rounded figure.
Is 117 kg a healthy weight?
It depends on your height. At 117kg, you could be a healthy weight, overweight, or obese depending on how tall you are. Shorter adults (under 5ft 4in) would typically be overweight or obese at this weight; taller adults (over 5ft 10in) may be in a healthy BMI range. Use the BMI calculator on this page to find your personal category.
What BMI is 117 kg at 5ft 8in?
At 5ft 8in (173cm), a weight of 117kg gives a BMI of approximately 24.2, which falls into the healthy weight category according to NHS guidelines. This is within the recommended range of 18.5 to 24.9. However, your GP can advise on what's optimal for your individual health profile.
How do I convert metric to imperial weight easily?
To convert metric to imperial weight, use the standard conversion: 1 kilogram = 2.20462 pounds, or 1 kilogram = 0.157473 stone. Our free weight converter on this page instantly converts between kg, stone, and pounds, so you can see all three units at once without doing the maths.
What does BMI not tell me about my health?
BMI doesn't distinguish between muscle and fat — athletes may have high BMI without excess body fat. It also ignores where fat is stored (waist measurement matters) and doesn't account for age, bone density, or medical conditions. For a fuller health picture, discuss your weight with your GP alongside other health markers like blood pressure and cholesterol.
