# How to Convert Meter to Kilometre in Java?

Converting meters to kilometres is a common task in various Java applications, especially when dealing with distances or measurements on different scales. Fortunately, performing this conversion is straightforward and requires only a few lines of code. In this section, we will go through the process of converting meters to kilometres in Java.

## Meters to Kilometres Conversion

Before we dive into the Java code, let's briefly discuss the relationship between meters and kilometres. The conversion factor between meters (m) and kilometres (km) is:

It implies that to convert meters to kilometres, we need to divide the value in meters by 1000. Similarly, to convert kilometres to meters, we would multiply the value in kilometres by 1000.

Now let's see how to implement the conversion in Java:

Filename: MeterToKilometerConverter.java

Output:

```2500.0 meters is equal to 2.5 kilometres.
```

Converting meters to kilometres is essential when dealing with distances on different scales. The metric system uses units like meters and kilometres to measure lengths, and these units are commonly used in various fields, such as engineering, geography, navigation, and physics. Understanding how to perform this conversion is crucial for many Java applications that involve handling distances or measurements.

## Extended Java Implementation

In addition to the basic conversion between meters and kilometres, we can further enhance our Java implementation to handle more scenarios and make it more versatile.

For example, we can add methods to convert from kilometres to meters and handle input validation to ensure that negative values or invalid inputs are not accepted. Here is an extended version of the Java implementation:

Filename: DistanceConverter.java

Output:

```2500.0 meters is equal to 2.5 kilometres.
3.75 kilometres is equal to 3750 meters.
```
