What Is 5ft3 in Centimetres?
5ft3 is equal to exactly 160 centimetres. This is a straightforward height conversion using the standard feet to cm measurement. At 160cm, you're slightly below the average UK adult female height of 161.6cm. Whether you're checking your height for health purposes, clothing sizes, or medical records, understanding your height in both imperial and metric measurements is useful in the UK where both systems are commonly used. Use our free BMI calculator above to check your healthy weight range for this height.

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.
Height Conversion Table and Formula
To convert 5ft3 to centimetres, use the standard feet to cm conversion formula: multiply feet by 30.48, then add inches converted to cm. For 5ft3 (5 feet and 3 inches), that's (5 × 30.48) + (3 × 2.54) = 160cm.
Heights near 5ft3:
- 5ft1 = 155cm
- 5ft2 = 157cm
- 5ft3 = 160cm
- 5ft4 = 163cm
- 5ft5 = 165cm
This height sits within the typical range for adult women in the UK. The centimetres to feet inches conversion is essential when using NHS health tools, as medical records may use metric measurements whilst patient discussions often reference imperial.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 5ft3 in metric measurements?
5ft3 equals 160 centimetres exactly. To convert, multiply 5 feet by 30.48 (160cm) and add 3 inches multiplied by 2.54 (7.62cm), giving 160cm total. This is the standard height conversion used in UK medical records.
Is 5ft3 a typical height for UK adults?
Yes, 5ft3 is close to the average height for UK adult women, which is approximately 161.6cm. For men, the average is around 175.3cm. Individual heights vary widely based on genetics, age, and other factors.
What weight is healthy at 5ft3?
According to NHS BMI guidelines, a healthy weight at 5ft3 (160cm) is roughly 47–64kg (7st 5lbs to 10st 1lbs). However, individual healthy weight depends on muscle mass and personal health factors. Use our BMI calculator to check your personal healthy weight range.
How do I convert my height between feet and centimetres?
Use the formula: (feet × 30.48) + (inches × 2.54) = centimetres. For example, 5ft3 = (5 × 30.48) + (3 × 2.54) = 160cm. Our free height converter on this page makes this instant.
Why do UK health records use both feet and centimetres?
The UK uses both imperial (feet and inches) and metric (centimetres) measurements. Patients often discuss height in feet and inches, while NHS clinical records and BMI calculations typically use centimetres. Knowing both measurements helps you navigate UK health information clearly.
