Converting between UTC and AM/PM time

Coordinated Universal Time (UTC) can be considered equivalent to Greenwich Mean Time (GMT) (when fractions of a second are not important). UTC is the system used to indicate time in meteorology and is recommended for all general timekeeping applications. Time on most weather maps is given given in Coordinated Universal Time, (as in the example below).


Resources are available to demonstrate the conversions from AM/PM time to UTC and also from UTC to AM/PM time.
