Comment convertir l'heure militaire (24h) en heures décimales ?

Pour convertir une heure au format 24h en heures décimales, isolez les heures (2 premiers chiffres) et divisez les minutes (2 derniers chiffres) par 60. Exemple : 0730 donne 7 + (30 ÷ 60) = 7,50 heures décimales ; 1645 donne 16 + (45 ÷ 60) = 16,75 heures décimales.

Heures Décimales = Heures + (Minutes ÷ 60)
0700 → 7.00
0830 → 8.50
1215 → 12.25
1745 → 17.75

📖 Guide Complet sur l'Heure Militaire et le Calcul de Paie Décimale

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

Frequently Asked Questions

1730 military time corresponds to 5:30 PM in standard 12-hour time (subtract 1200 from 1730). In decimal hours of the day, it is 17.50 hours ($17 + 30/60$). If an employee worked from 0900 to 1730 with a 30-minute lunch, they worked $8.5 - 0.5 = 8.00$ decimal hours.
Both represent midnight, but with distinct operational meanings. 0000 represents the beginning of the day (e.g. Monday 0000 is 12:00:00 AM Monday). 2400 represents the exact conclusion of the day (e.g. Monday 2400 is the exact end of Monday, identical to Tuesday 0000).
Under FLSA regulations, bona fide meal periods (typically 30 minutes or longer where the employee is completely relieved from duty) are non-compensable. The calculator converts your break minutes into decimal hours (e.g., 30 min = 0.50h, 45 min = 0.75h) and automatically subtracts it from total elapsed shift time before applying wage multipliers.
Yes! Select the "Legal 6-Minute Tenths (0.1h)" preset in the Rounding Rule dropdown. This applies the standard American Bar Association (ABA) 6-minute billing intervals where 1–6 minutes = 0.1h, 7–12 minutes = 0.2h, up to 55–60 minutes = 1.0h.
