Time Conversion Formula:
1 Hour = 3600 Seconds | 1 Second = 0.000277778 Hours
Seconds = Hours × 3600 | Hours = Seconds ÷ 3600 (Results: 3 decimal places)
*Derived from: 1 Hour = 60 Minutes; 1 Minute = 60 Seconds → 60×60 = 3600 Seconds/Hour
Standard time unit: Scheduling, work shifts, travel duration, project timelines

| Unit | Symbol | Conversion Factor | Common Uses |
|---|---|---|---|
| Hour | h | 1 h = 3600 s = 60 min | Scheduling, work shifts, travel time, project deadlines, event durations |
| Second | s | 1 s = 0.000277778 h = 0.0166667 min | Precise timing, scientific experiments, sports, cooking, technical calculations |
| Hours (h) | ≈ | Seconds (s) | Application |
|---|---|---|---|
| 0.25 | ≈ | 900.000 | 15 minutes (short break) |
| 0.5 | ≈ | 1800.000 | 30 minutes (meeting duration) |
| 1 | ≈ | 3600.000 | 1 hour (work block) |
| 8 | ≈ | 28800.000 | 8-hour workday |
| 24 | ≈ | 86400.000 | 24-hour day |
| 168 | ≈ | 604800.000 | 7-day week |
About hours, seconds, and time conversions
The conversion factor comes from the standard division of time:
Precise factor: 1 hour = 3600.0 seconds (exact, no rounding needed)
Practical use: 3-6 decimal places are sufficient for most everyday and professional calculations
The choice depends on time scale and precision needs:
Use these related conversion factors for full time unit flexibility:
1 minute = 60 seconds | 1 hour = 60 minutes | 1 day = 24 hours
1 day = 86400 seconds | 1 week = 168 hours = 604800 seconds
Practical cross-conversion examples:
This converter can be used as a base for all time conversions — convert hours/seconds first, then use the above factors to switch to other units.
