What Is 77 Kg in Stones and Pounds?
77 kilograms is equal to 12 stone and 2 pounds (12st 2lbs). To convert kilograms to stone, divide by 6.35029 — the standard conversion factor used across the UK. This weight falls into the overweight category for most UK adults, though BMI context depends on your height. Use our free BMI calculator above to check where 77kg places you on the NHS weight scale, and our weight converter to switch between metric and imperial measurements instantly.

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.
77 Kg to Stone Conversion Table and Formula
77 kg = 12 stone 2 lbs (12st 2lbs)
To convert kilogram to stone conversion manually, use this formula: kg ÷ 6.35029 = stone. So 77 ÷ 6.35029 = 12.14 stone (which equals 12 stone and 2 pounds).
Here are nearby values in the metric to imperial weight conversion range:
- 75 kg = 11st 11lbs
- 76 kg = 11st 13lbs
- 77 kg = 12st 2lbs
- 78 kg = 12st 4lbs
- 79 kg = 12st 6lbs
Each kilogram adds approximately 2.2 pounds or 0.16 stone to your weight.

Is 77 Kg a Healthy Weight? BMI and Health Context
Whether 77kg is healthy depends on your height. At average UK female height (162cm / 5ft 4in), 77kg gives a BMI of 29.3 — overweight according to NHS guidelines. At average UK male height (175cm / 5ft 9in), 77kg gives a BMI of 25.2 — within the healthy range.
The NHS recommends a healthy BMI of 18.5 to 24.9 for adults. If your BMI is above 25, modest weight loss of 5–10% can improve blood pressure, blood sugar control, and reduce strain on joints. Try our free GLP-1 weight loss calculator to explore how lifestyle changes or weight management support might help, and track your progress with our progress tracker.
If you're concerned about your weight or health at 77kg, speak to your GP. They can assess your individual circumstances, including family history, fitness level, and any weight-related health conditions. Remember that BMI is a screening tool only — it doesn't account for muscle mass or where fat is stored. Your GP can provide personalised guidance on whether weight loss is appropriate for you.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 77kg to stone and pounds myself?
Divide 77 by 6.35029 to get stone (result: 12.14 stone). The 0.14 converts to pounds by multiplying by 14 (0.14 × 14 ≈ 2 pounds). So 77kg = 12 stone 2 pounds. Our free weight converter above does this instantly.
Is 77kg overweight or healthy?
It depends on height. At 5ft 4in, 77kg is overweight (BMI 29.3). At 5ft 9in, it's healthy (BMI 25.2). Use our BMI calculator above to check your personal BMI — it accounts for your exact height and weight.
What's the healthy weight range for someone who weighs 77kg now?
For someone 5ft 6in tall, the healthy weight range is 52–70kg. For someone 5ft 10in, it's 58–80kg. Your GP can advise on your personal healthy range based on your health history and body composition.
How much weight would I need to lose from 77kg to reach a healthy BMI?
This varies by height and current BMI. Our GLP-1 weight loss calculator can project realistic weight loss scenarios. The NHS recommends gradual loss of 0.5–1kg per week, which is more sustainable than rapid loss.
Can I use 77kg as a reference point for weight loss?
Yes — tracking from a baseline weight helps measure progress. Our free progress tracker lets you log your weight over time and see trends. Even 5–10% loss from 77kg brings health benefits like better blood pressure and blood sugar control.
