Changing the Latitude Longitude display format in Compass

I would like to change the format of the Latitude and Longitude to decimal degrees instead of degrees/minutes/seconds in the Compass app. I can't seem to find where the setting is to change this.

For example, I would like to display in the following format:

46.266944,-121.627222

not this format:

46 16' 1", -121 37' 38"

Thank you
