What is Feet to CM Conversion?

Feet to centimetres conversion is the process of transforming height measurements from the imperial system (feet and inches) to the metric system (centimetres). In the United Kingdom, this conversion is essential because while people commonly use feet and inches in everyday conversation, official documents, medical records, and international forms typically require metric measurements.

The UK has a unique relationship with measurement systems. Since the 1965 Weights and Measures Act officially adopted the metric system, the country has been gradually transitioning from imperial to metric units. However, imperial measurements remain deeply embedded in British culture, particularly for personal height and weight.

Why This Converter Matters for UK Residents

  • NHS and Medical Records: All UK healthcare providers record height in centimetres or metres. When you visit your GP, hospital, or complete medical forms, metric measurements are required.
  • Passport Applications: UK passport forms accept both systems but metric is preferred for international recognition.
  • Employment: Job applications for certain roles (military, aviation, emergency services) specify height requirements in centimetres.
  • International Documents: When dealing with EU or international forms, metric measurements are mandatory.
  • Sports and Fitness: Professional sports, gym equipment, and fitness trackers typically use metric measurements.
  • Online Shopping: Clothing sizes from international retailers often use centimetres for body measurements.

The Conversion Formula

Essential Conversion Factors: 1 foot = 30.48 cm (exactly)
1 inch = 2.54 cm (exactly)
1 foot = 12 inches
100 cm = 1 metre
Feet and Inches to CM Formula: CM = (Feet × 30.48) + (Inches × 2.54)

Step-by-Step Worked Examples

Example 1: Convert 5 feet 8 inches to CM

Step 1: Convert feet to cm: 5 × 30.48 = 152.40 cm
Step 2: Convert inches to cm: 8 × 2.54 = 20.32 cm
Step 3: Add together: 152.40 + 20.32 = 172.72 cm

Example 2: Convert 6 feet exactly to CM

6 × 30.48 = 182.88 cm (or 1.83 metres)

Example 3: Convert 175 cm to Feet and Inches

Step 1: Divide cm by 2.54 to get total inches: 175 ÷ 2.54 = 68.9 inches
Step 2: Divide by 12 for feet: 68.9 ÷ 12 = 5 feet with remainder
Step 3: Remainder is inches: 68.9 - 60 = 8.9 inches
Result: 5 feet 9 inches (5'9")

Tips for Accurate Height Measurement

  • Measure in the morning: People are typically 1-2 cm taller in the morning due to spinal compression throughout the day.
  • Stand straight: Keep your back against a wall, heels together, and look straight ahead at the horizon.
  • Remove shoes: Always measure barefoot or in thin socks for accuracy.
  • Use a flat surface: Place a book or ruler flat on top of your head, perpendicular to the wall.
  • Round appropriately: For official documents, round to the nearest whole centimetre.
  • Double-check calculations: Use our calculator to verify any manual conversions.
  • Know your baseline: Memorise your height in both systems for quick reference.
  • Account for posture: Poor posture can reduce measured height by 2-5 cm.

Common Mistakes to Avoid

  • Confusing feet with inches: Remember there are 12 inches in a foot, not 10.
  • Wrong conversion factor: Using 2.5 instead of 2.54 for inches leads to significant errors.
  • Forgetting the inches: When someone says "5'8", both numbers matter - don't ignore the 8 inches.
  • Rounding too early: Complete the full calculation before rounding to avoid cumulative errors.
  • Mixing up units: Don't confuse centimetres with metres (100 cm = 1 metre).
  • Measuring with shoes on: Shoes add 2-5 cm depending on style - always measure barefoot.
  • Assuming 30 cm per foot: The correct factor is 30.48 cm, not 30 cm.
