Is 137 Lbs A Healthy Weight?
137 pounds converts to approximately 62.1 kilograms. Whether this is a healthy weight depends entirely on your height. For some adults it's a healthy weight, for others it falls into the overweight range. This guide shows you how to assess if 137 lbs is right for your height using NHS BMI guidelines, plus what to consider beyond just the number on the scales.

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.
Healthy Weight Ranges By Height
137 lbs (62.1 kg) falls into different BMI categories depending on your height. Here are three real examples:
- At 5ft 3in (160 cm): 137 lbs gives a BMI of 24.3 — this is a healthy weight according to NHS guidelines (healthy range: 18.5–24.9)
- At 5ft 6in (168 cm): 137 lbs gives a BMI of 22.1 — solidly in the healthy range
- At 5ft (152 cm): 137 lbs gives a BMI of 29.5 — this is overweight according to NHS standards (overweight range: 25–29.9)
Use our free BMI calculator above to find your exact BMI and healthy weight range for your specific height. You can also use the weight converter to switch between kilograms, stone, and pounds easily.

NHS Guidance & What To Do Next
The NHS recommends a healthy BMI of 18.5 to 24.9 for most adults. If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the recommended healthy range is slightly lower (18.5–22.9), as these groups face higher health risks at lower BMI levels.
Beyond BMI, waist circumference matters too. A waist over 94 cm (37 inches) for men or 80 cm (31.5 inches) for women suggests increased health risk, even at a healthy BMI. If you're concerned about your weight or health, speak to your GP who can offer personalised guidance based on your overall fitness, medical history, and individual circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 137 lbs in kilograms exactly?
137 pounds equals 62.14 kilograms. This conversion uses the standard formula: lbs × 0.453592 = kg. You can verify this using our free weight converter above, which also switches between stone, pounds, and kilograms.
Is 137 lbs overweight or healthy?

What's the healthy weight range at my height if I'm 137 lbs?
For a healthy BMI (18.5–24.9), your ideal weight range depends on height. At 5ft 6in, healthy weight is roughly 118–159 lbs. At 5ft 9in, it's 128–172 lbs. Calculate your exact range using our free BMI calculator above.
Do I need to lose weight if I'm 137 lbs?
Only if your BMI is above 25 for your height. If your BMI is healthy, weight loss isn't necessary. If you're overweight or obese, even small reductions (5–10%) can improve health markers. Speak to your GP for personalised advice.
Why does height matter for weight?
BMI accounts for height because taller people naturally weigh more. The same weight distributed over a taller frame spreads differently than on a shorter frame. This is why 137 lbs can be healthy for one person and overweight for another.
