How to Convert Height from Feet to cm — Free Converter (2026)

Height measurements vary by country — the US uses feet and inches while most of the world uses centimetres or metres. The free height converter handles all four units simultaneously: feet, inches, centimetres, and metres. Enter a value in any unit and see the others update instantly.

How to Use the Tool

1. Type your height into any input field — feet, inches (or feet and inches combined), centimetres, or metres.
2. The remaining three fields update automatically as you type. No "convert" button needed.
3. Copy the value you need — for example, the centimetre result for a medical form or the feet-and-inches result for a US clothing size chart.

How It Works

All conversions are anchored to the inch, which is defined as exactly 2.54 centimetres:

• 1 inch = 2.54 cm
• 1 foot = 12 inches = 30.48 cm
• 1 metre = 100 cm ≈ 3 ft 3.37 in

For example, a person who is 5 ft 11 in tall converts as follows: total inches = (5 × 12) + 11 = 71 in; centimetres = 71 × 2.54 = 180.34 cm; metres = 180.34 ÷ 100 = 1.8034 m.

Use Cases

• International travel — completing forms at border control, hotels, or car hire desks that ask for height in unfamiliar units.
• Medical forms — most clinical records outside the US use centimetres; US patients travelling abroad often need to convert.
• Clothing and fashion — international size charts for trousers, dresses, and swimwear commonly list height in cm or in ft/in depending on the brand's home market.
• Fitness and sports — athlete profiles, gym registration forms, and sports statistics mix units depending on the sport and country.
• Online shopping — furniture, shelving, and home appliance listings differ by retailer country; knowing your doorway height in both units prevents ordering mistakes.

Frequently Asked Questions

How many cm is 5 foot 11?

5 feet 11 inches is 180.34 cm (or 1.8034 m). To work it out manually: convert 5 ft 11 in to total inches (5 × 12 + 11 = 71 inches), then multiply by 2.54 (71 × 2.54 = 180.34 cm).

How do I convert 180 cm to feet and inches?

Divide by 2.54 to get total inches: 180 ÷ 2.54 ≈ 70.87 in. Divide by 12 to get feet: 70.87 ÷ 12 = 5 remainder 10.87, so 180 cm ≈ 5 ft 10.87 in (commonly rounded to 5 ft 11 in). The tool handles the rounding for you.

Why does height measurement differ by country?

The United States, Liberia, and Myanmar are the only countries that have not officially adopted the metric system as the national standard. Most of the world uses centimetres and metres for height, which are part of the International System of Units (SI). The imperial system (feet and inches) persists in everyday US use through convention and cultural inertia rather than any technical advantage.
