Map Radius and Zoom Level

There are two settings which may be a bit confusing, so here is some clarity that also will serve as a reference you can come back to.

Map Radius

If you Google for instance “15 miles equals how many kilometers?“, you will get the result “24.1402” But when you enter this, it calculates as the ” Radius: 24.14 kilometers / 14.967 miles”. This is not quite 15 miles. There seems to be a calculation discrepancy in the equation somehow, but rather than spending any more time on this, if you want your maps to display miles without any decimals, use the numbers below.

Distance

kilometers=?miles

To display
Radius: 8.06 kilometers / 5 miles
Enter 8.06372

To display
Radius 9.68 kilometers / 6 miles
Enter 9.6769

To Display
Radius: 24.19 kilometers / 15 miles
Enter 24.194

To Display
Radius: 48.39 kilometers / 30 miles
Enter 48.3865

Zoom

The lower the number, the more zoomed out you become.

So to display the following radius best set the Zoom Levels as follows:

5 miles = 11.675 zoom level

6 miles = 11 zoom level

15 miles = 9.87 zoom level

30 miles = 9 zoom level
