# How To Change Miles To Km In Facebook Ads

In the world of online marketing, accuracy is crucial. This is especially important when it comes to setting geographical parameters. When creating a Facebook advertisement, you can select a precise audience based on their location. However, the default setting for distance is in miles, which can be inconvenient for those in countries that use kilometers as the standard unit of distance.

So, how do you change this setting from miles to kilometers in Facebook Ads? Unfortunately, Facebook does not currently offer a built-in feature allowing you to make this change. But don’t worry, there is a simple equation you can use to convert miles to kilometers:

1 mile = 1.60934 kilometers

Therefore, all you need to do is multiply your desired radius in miles by 1.60934 to get the equivalent in kilometers. For example, if you want to target people within a 10-mile radius, you would need to set your radius to approximately 16 kilometers (10 miles * 1.60934 = 16.0934 kilometers).

This workaround may feel a bit cumbersome, but it’s currently the best solution we have. Here’s a more concrete example:

Let’s say we want to set our location to the city center of London, and we want to target people within a 10-mile radius. We firstly set the location as follows:

Location: London, United Kingdom

Then, we do the conversion from miles to kilometers:

10 miles * 1.60934 = 16.0934 Kilometers

So, we now set our radius to 16 kilometers:
