To convert hours to minutes: multiply by 60. To convert hours to seconds: multiply by 3,600.
1 h = 60 min = 3,600 s = 3.6 × 10⁶ ms. There are 24 hours in a day and 8,760 in a non-leap year.
For example, 1 Hour (h) = 3600000000 Microsecond (µs).
| Hour (h) | Microsecond (µs) |
|---|---|
| 0.1 | 360000000 |
| 0.5 | 1800000000 |
| 1 | 3600000000 |
| 2 | 7200000000 |
| 5 | 18000000000 |
| 10 | 36000000000 |
| 25 | 90000000000 |
| 50 | 180000000000 |
| 100 | 360000000000 |
| 500 | 1.800000e+12 |
| 1000 | 3.600000e+12 |
The hour is a unit of time equal to 60 minutes, or 3,600 seconds.
1 h = 60 min = 3,600 s = 3.6 × 10⁶ ms. There are 24 hours in a day and 8,760 in a non-leap year.
To convert hours to minutes: multiply by 60. To convert hours to seconds: multiply by 3,600.
Work schedules, flight durations, speed limits (km/h, mph), cooking times, and pay rates (hourly wages).
Before mechanical clocks, 'hours' varied by season — a summer daytime hour was longer than a winter one. These were called 'temporal hours.'
Converting decimal hours to minutes/seconds incorrectly: 2.5 h = 2 h 30 min, not 2 h 50 min. Think base-60.
The kilowatt-hour (kWh) on your electric bill is energy = power × time. 1 kWh = using 1,000 watts for 1 hour.
The microsecond is a unit of time equal to 10⁻⁶ seconds — one millionth of a second.
1 µs = 10⁻⁶ s = 1,000 ns = 0.001 ms. Light travels about 300 m in one microsecond.
To convert µs to seconds: multiply by 10⁻⁶. To convert µs to milliseconds: divide by 1,000.
Audio sampling (CD quality ≈ 22.7 µs per sample), USB data transfer timing, radar echo delays, and strobe flash durations.
A camera flash from a xenon strobe tube lasts about 1,000 µs (1 ms), but specialized flashes can be as short as 0.5 µs.
Writing 'us' instead of 'µs' in formal contexts. Also confusing µs with ms — a factor of 1,000 difference.
Micro = millionth. A microsecond is to a second what a second is to about 11.6 days. Think of sound traveling 0.34 mm.
