If it is 3:00 PM, what is the military time format?

To convert standard time to military time, you take the hour and, if it is in the PM, add 12 to it for any hour after 12 PM. At 3:00 PM, you simply add 12 to the hour (3 + 12), which results in 15. Therefore, the military time format for 3:00 PM is 1500. This follows the standard conventions of military time, where hours are represented on a 24-hour clock, eliminating any ambiguity between AM and PM.
