Length Converter

### What is a Length Converter?

A Length Converter is an online calculator that converts distance units such as metres (m), kilometres (km), centimetres (cm), millimetres (mm), micrometres, nanometres, inches (in), feet (ft), yards (yd), miles (mi) and nautical miles into one another. It relies on established conversion factors, for example 1 inch = 2.54 centimetres and 1 mile = 1.609 kilometres, to provide accurate results instantly.

### Why use it?

Manually converting between metric and imperial units can be error‑prone and time‑consuming. Whether you're working on a science assignment, planning a run, building furniture or comparing travel distances, you often need to switch between centimetres and inches or miles and kilometres. Our Length Converter automates these calculations, saves time and ensures precision.

### How to use the tool

1. Enter the numeric length value you want to convert.
2. Choose the unit of your input value from the first dropdown (m, cm, mm, km, in, ft, yd, mi, etc.).
3. Select the unit you want to convert to from the second dropdown.
4. Click the "Convert" button. The equivalent length will appear instantly.
