Length Unit Converter

This calculator makes it easy to convert between the most commonly used length units: centimetres, metres, kilometres, inches, and feet. Whether you are working on a construction project, planning a trip, or simply curious, you can quickly find the right value. Just enter your number and choose the unit you are converting from, and the result will appear in all five units instantly.

Metric vs. Imperial System

In Denmark and most of Europe, the metric system (centimetres, metres, kilometres) is used in everyday life. The imperial system (inches, feet) is primarily used in the USA and UK. Converting between the two systems is a frequent task, especially when shopping online from foreign stores, following construction guides, or comparing heights and distances in international contexts.

How the Conversion Works

The calculator first converts your entered value to centimetres as an intermediate step, then converts from centimetres to all other units. The conversion factors are: 1 metre = 100 cm, 1 kilometre = 100,000 cm, 1 inch = 2.54 cm, and 1 foot = 30.48 cm. All results are rounded to four decimal places for precision.

Common Use Cases

Length conversion is useful in many everyday situations. You might convert your height from centimetres to feet and inches for an international profile, work out how many metres a given number of feet equals for a building project, or convert kilometres to approximate miles via feet. The calculator is also well suited for schoolwork, scientific calculations, and when travelling to countries that use the imperial system.

Frequently Asked Questions

How many centimetres are in an inch?

One inch equals exactly 2.54 centimetres. This conversion factor has been internationally standardised since 1959 and is used worldwide.

How do you convert metres to feet?

To convert metres to feet, multiply the number of metres by 3.2808. One metre equals approximately 3 feet and 3.37 inches. Example: 10 metres = 32.808 feet.

What is the difference between the metric and imperial systems?

The metric system is based on powers of ten (10, 100, 1,000, etc.) and uses units such as centimetres, metres, and kilometres. The imperial system uses inches, feet, yards, and miles. Most countries use the metric system, while the USA, Myanmar, and Liberia still primarily use the imperial system.

How many kilometres are in a mile?

One mile equals 1.60934 kilometres. Conversely, one kilometre equals approximately 0.6214 miles. Although this calculator does not directly include miles, you can use the feet result and divide by 5,280 to obtain miles.
