How to convert 1630 military time to standard time
1630 is after noon, so subtract 12 from the hour: 16 minus 12 is 4. Keep the 30 minutes and add PM, which gives 4:30 PM. The same subtraction converts every military time from 1300 to 2359. To go the other way, add 12 to the hour of 4:30 PM: 4 plus 12 is 16, so 4:30 PM is 1630.
How to say 1630
1630 is said "sixteen thirty": the hour as "sixteen" and then the minutes as a plain number. Nobody says "half past" in military time, and nobody says "hundred" once there are minutes on the clock. "Sixteen thirty hours" is common in speech, though Army correspondence rules (AR 25-50, paragraph 1-26) leave the word hours out in writing.
