Find the latitude and longitude of a point using Google Maps.
This tool allows you to calculate distance between points on a google map and total route length
You can convert between geographic coordinates and Universal Transverse Mercator (UTM) coordinates using this form.
This tool allows you to use Google Maps to define an area and then find out the measurement of the enclosed area. You can also generate a KML file from the input data.
E.g., draw a circle of 36 km radius around downtown Halifax, Nova Scotia as in My Map. It can be exported as a KML file as well. A little fussy to use, but it is workable.
