Explained with a live converter, reference tables, charts, and a step-by-step guide.
Enter a standard time (e.g. 2:30 PM) to convert it instantly into military 24-hour time.
Standard time splits the day into two halves: AM (Latin ante meridiem, before noon) runs from midnight until just before 12 noon. PM (post meridiem, after noon) runs from 12 noon until just before midnight.
The two tricky cases: midnight is 12:00 AM (not PM) and noon is 12:00 PM (not AM). Military time avoids this entirely — 0000 and 1200 are unambiguous.

Common decimal hours and their equivalent in hours and minutes — handy for timesheets.
| Decimal hours | Hours & minutes |
|---|---|
| 0.1 | 0h 6m |
| 0.25 | 0h 15m |
| 0.33 | 0h 20m |
| 0.5 | 0h 30m |
| 0.66 | 0h 40m |
| 0.75 | 0h 45m |
| 0.9 | 0h 54m |
| 1 | 1h 0m |
| 1.25 | 1h 15m |
| 1.5 | 1h 30m |
| 1.75 | 1h 45m |
| 2 | 2h 0m |
| 7.5 | 7h 30m |
| 7.75 | 7h 45m |
| 8 | 8h 0m |
A time format only decides how a moment is written — not when it happens. Military time, standard time, Unix timestamps, and decimal time are different notations for the same information.
Converting between them is therefore exact and never changes. The only rounding is in decimal time, where seconds are rounded to whole minutes.
Military time is used by the military, aviation, hospitals, and emergency services because it is unambiguous. Unix timestamps live in databases, log files, and APIs. Decimal time appears on timesheets and in payroll.
Enter a standard time (e.g. 2:30 PM) to convert it instantly into military 24-hour time.
For AM times, drop the colon (8:15 AM becomes 0815), except 12:00 AM which is 0000. For PM times, add 12 to the hour (2:30 PM becomes 1430), except 12:00 PM which stays 1200.
Midnight (12:00 AM) is 0000 and noon (12:00 PM) is 1200. Military time uses no AM/PM marker, so there is no ambiguity.
Yes. Converting between time formats is a pure notation change — the same moment, just written differently. There is no rounding except minute-rounding for decimal time.
