What Is 137 Kg In Pounds And BMI?
137 kilograms equals approximately 302 pounds (or 301.9 lbs to be precise). However, your BMI — and whether this weight is healthy for you — depends entirely on your height. Using our free BMI calculator above, you can find your exact BMI in seconds. This guide shows you what BMI 137 kg gives at common UK heights and what each means according to NHS guidelines.

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.
137 Kg BMI At Different Heights
137 kg is a significant weight, and BMI varies considerably depending on how tall you are. Here's what BMI this weight produces at typical UK adult heights:
- At 160 cm (5ft 3in): BMI of 53.3 — Severely obese (Class III)
- At 165 cm (5ft 5in): BMI of 50.3 — Severely obese (Class III)
- At 170 cm (5ft 7in): BMI of 47.4 — Severely obese (Class III)
- At 175 cm (5ft 9in): BMI of 44.7 — Severely obese (Class III)
- At 180 cm (5ft 11in): BMI of 42.3 — Severely obese (Class III)
- At 185 cm (6ft 1in): BMI of 40.1 — Severely obese (Class III)
At 137 kg, most adults fall into the severely obese category according to NHS BMI thresholds. Your GP can provide personalised health advice based on your specific height and overall health profile.

Understanding NHS BMI Categories And Limitations
The NHS BMI categories are: Underweight (below 18.5), Healthy weight (18.5–24.9), Overweight (25.0–29.9), Obese Class I (30.0–34.9), Obese Class II (35.0–39.9), and Severely obese (40.0+). At 137 kg, most heights produce a BMI above 40.
It's important to understand BMI limitations: it does not distinguish between muscle and fat, doesn't account for where fat is stored (waist measurement matters too), and may be less accurate for very muscular individuals or the elderly. Speak to your GP for a full health assessment — BMI is a screening tool, not a diagnosis. You can use the free weight converter on this page to check your weight in stone and pounds as well.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 137 kg in pounds exactly?
137 kg equals 301.9 pounds (often rounded to 302 lbs). To convert kilograms to pounds, multiply by 2.20462. For stone and pounds, 137 kg is approximately 21 stone 9.9 pounds, though using our free weight converter above gives exact conversions instantly.
Is 137 kg overweight or obese?
At 137 kg, the BMI category depends on height. For most UK adults, this weight produces a BMI in the severely obese range (Class III, BMI 40+). However, only your GP can assess your individual health status. Factors like muscle mass, age, and existing health conditions all matter.
What's a healthy weight for my height if I'm currently 137 kg?
Healthy weight ranges vary by height. For example, at 5ft 7in (170 cm), the NHS healthy weight range is roughly 50–68 kg. Use our free BMI calculator above to find the healthy weight range for your specific height, then speak to your GP about realistic weight loss goals.
Can I use BMI alone to check my health?
BMI is a useful screening tool but has limitations — it doesn't account for muscle mass, waist circumference, age, or ethnicity. Your GP uses BMI alongside other measurements like waist circumference and blood pressure for a complete health picture. Always discuss your weight with your healthcare professional.
What weight loss support is available in the UK?
The NHS offers tier 1 weight management support through your GP, community programmes, and digital tools. Specialist services (tier 3) may offer prescription weight loss treatments for eligible adults. Your GP can discuss whether medication like GLP-1 injections might help alongside lifestyle changes.
