Como converter hora militar (24h) em horas decimais?
Para converter hora militar de 24h em horas decimais, separe as horas (primeiros 2 dígitos) e divida os minutos (últimos 2 dígitos) por 60. Exemplo: 0730 equivale a 7 + (30 ÷ 60) = 7,50 horas decimais; 1645 equivale a 16 + (45 ÷ 60) = 16,75 horas decimais.

📖 Guia Completo sobre Hora Militar e Cálculo Decimal na Folha
In 24/7 continuous operations—such as healthcare emergency rooms, manufacturing plants, civil aviation, law enforcement, and logistics fleets—time is recorded in the 24-hour military clock format to eliminate catastrophic AM/PM ambiguities. However, modern corporate payroll software and accounting ERPs (QuickBooks, ADP, Workday, Paychex) do not accept 24-hour clock strings for wage multiplication. They require base-10 decimal hours.
The Core Mathematical Conversion Formulas
1. Military to Hours & Minutes: 1645 = 16 Hours and 45 Minutes
2. Decimal Conversion: Decimal Hours = Hours + (Minutes ÷ 60)
3. Example: 16 + (45 ÷ 60) = 16 + 0.75 = 16.75 Decimal Hours
4. Shift Worked Duration: Worked Decimal = (Clock Out Decimal - Clock In Decimal) - Unpaid Break Decimal
1. How to Handle Midnight Crossover in Overnight Military Shifts
One of the most frequent accounting pitfalls occurs when third-shift or night-shift workers punch in during the evening (e.g. 22:00) and punch out the following morning (e.g. 06:30). Standard subtraction (0630 - 2200) results in a negative integer error.
To solve this correctly:
- Method A (Modulo Arithmetic): $\text{Total Hours} = (\text{Clock Out} - \text{Clock In} + 24) \pmod{24}$. For example, $(6.5 - 22.0 + 24) = 8.5\text{ hours}$.
- Method B (Midnight Split): Calculate time until midnight ($2400 - 2200 = 2\text{ hours}$) and add morning elapsed time ($0630 - 0000 = 6.5\text{ hours}$). Sum $= 2.0 + 6.5 = 8.5\text{ decimal hours}$.
2. Applying the FLSA 7-Minute Rule to 24-Hour Military Punches
Under federal Fair Labor Standards Act guidelines (29 CFR § 785.48(b)), employers who round time clock punches to 15-minute (0.25-hour) increments must follow the 7-minute rounding rule:
| Minute Punch Window | Rounded Minute | Decimal Equivalent | FLSA Payroll Rule |
|---|---|---|---|
| :00 to :07 past hour | :00 | .00h | Rounds DOWN to previous quarter hour |
| :08 to :22 past hour | :15 | .25h | Rounds to 15 minutes past |
| :23 to :37 past hour | :30 | .50h | Rounds to 30 minutes past |
| :38 to :52 past hour | :45 | .75h | Rounds to 45 minutes past |
| :53 to :59 past hour | :00 (Next Hour) | 1.00h | Rounds UP to next full hour |
