Convert between hours (h) and minutes (min) for scheduling, travel planning, work hours, and daily time management with precision.
Conversion Factor:
1 hour (h) = 60 minutes (min)
min = h × 60 | h = min ÷ 60
Accepts decimal values (e.g., 1.5 h = 90 min)

Fundamental time units used globally for measuring duration in daily life, work, and travel
Common activities and their approximate duration in both units:
| Activity | Hours (h) | Minutes (min) |
|---|---|---|
| Short coffee break | 0.25–0.5 h | 15–30 min |
| Average commute | 0.5–1 h | 30–60 min |
| Feature-length movie | 1.5–2.5 h | 90–150 min |
| Standard work day (8 hours) | 8 h | 480 min |
| International flight (NY to London) | 7–8 h | 420–480 min |
| Full night’s sleep | 7–9 h | 420–540 min |
Common time conversions for scheduling, work, and daily activities
| Hours (h) | = | Minutes (min) | Practical Context |
|---|---|---|---|
| 0.1 h | = | 6 min | Quick task (e.g., making tea) |
| 0.25 h | = | 15 min | Short break, quick walk |
| 0.5 h | = | 30 min | Half-hour meeting, workout |
| 0.75 h | = | 45 min | Long commute, cooking meal |
| 1 h | = | 60 min | Full meeting, long workout |
| 1.5 h | = | 90 min | Movie, extended work session |
| 4 h | = | 240 min | Half work day, road trip segment |
| 8 h | = | 480 min | Standard work day |
All conversions use the factor: 1 h = 60 min | 1 min = 1/60 h ≈ 0.0167 h
Common questions about hours and minutes
The 60-minute hour originates from ancient Babylonian mathematics, which used a base-60 (sexagesimal) number system. This system was adopted by Greek astronomers in the 2nd century BCE for tracking celestial movements, as 60 is divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30—making it easy to divide time into smaller intervals.
1 hour = 60 minutes (base-60 division)
1 minute = 60 seconds (same base-60 logic)
This system became standard globally due to its practicality for timekeeping and astronomy.
Use hours (h) for:
Use minutes (min) for:
Follow these steps to convert mixed time to decimal hours (common for time tracking):
Example: 1 h 20 min → 20 min ÷ 60 = 0.333... h
Total decimal hours: 1 + 0.333... = 1.333... h (or 1.33 h when rounded)
To reverse it (decimal hours to hours/minutes), multiply the decimal part by 60 to get minutes.
Yes—hours and minutes are universal time units used in every country. While some cultures historically used different time systems (e.g., ancient Egyptian 12-hour nights/day), the 24-hour day divided into 60-minute hours and 60-second minutes is now the global standard.
The only variation is in time display: some countries use 12-hour format (AM/PM, e.g., US, UK) while others use 24-hour format (e.g., most of Europe, Asia). But the underlying units (hours and minutes) remain the same.
For everyday use, the conversion is exact—1 hour is defined as exactly 60 minutes, and 1 minute as exactly 60 seconds. However, for scientific purposes (e.g., astronomy, GPS), time is measured more precisely using atomic clocks, and a "solar day" (time between sunrises) is slightly longer than 24 hours (≈24h 0m 2.8s).
To account for this, leap seconds are occasionally added to Coordinated Universal Time (UTC). But for daily activities like scheduling, cooking, or work tracking, the 60-minute hour is perfectly accurate.
