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) = 3.600000e+15 Picosecond (ps).
| Hour (h) | Picosecond (ps) |
|---|---|
| 0.1 | 3.600000e+14 |
| 0.5 | 1.800000e+15 |
| 1 | 3.600000e+15 |
| 2 | 7.200000e+15 |
| 5 | 1.800000e+16 |
| 10 | 3.600000e+16 |
| 25 | 9.000000e+16 |
| 50 | 1.800000e+17 |
| 100 | 3.600000e+17 |
| 500 | 1.800000e+18 |
| 1000 | 3.600000e+18 |
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 picosecond is a unit of time equal to 10⁻¹² seconds — one trillionth of a second.
1 ps = 10⁻¹² s = 1,000 fs = 0.001 ns. Light travels about 0.3 mm in one picosecond.
To convert ps to seconds: multiply by 10⁻¹². To convert ps to nanoseconds: divide by 1,000.
Fiber optic signal timing, semiconductor switching speeds, and laser pulse durations in medical and industrial applications.
Light travels only about 0.3 mm (the thickness of a hair) in one picosecond. Modern transistors switch in just a few picoseconds.
Confusing picoseconds with nanoseconds — they differ by a factor of 1,000. In computing specs, read units carefully.
Think of light distance: light goes ~30 cm in 1 ns and only ~0.3 mm in 1 ps. That's the speed/time relationship at this scale.
