Radius Map Tool - Draw a Circle with a Radius on the Map

What Is a Radius Map Tool?

A radius map tool lets you select a point on a map and draw a circle with that point as its center. The free Radius Map Tool on onlinecompass.net displays the radius of the circle you are drawing in real time. After you draw the circle, hover your mouse over its center to see the radius, the area, and the geographic coordinates (latitude and longitude) of the center.

If the radius of the drawn circle is less than 1,000 meters, the tool shows the radius in meters and miles at the center. If the radius is 1,000 meters or more, it displays the radius in kilometers and miles.
