To convert µs to seconds: multiply by 10⁻⁶. To convert µs to milliseconds: divide by 1,000.
1 µs = 10⁻⁶ s = 1,000 ns = 0.001 ms. Light travels about 300 m in one microsecond.
For example, 1 Microsecond (µs) = 3.170979e-17 Millennium (mil).
| Microsecond (µs) | Millennium (mil) |
|---|---|
| 0.1 | 3.170979e-18 |
| 0.5 | 1.585490e-17 |
| 1 | 3.170979e-17 |
| 2 | 6.341958e-17 |
| 5 | 1.585490e-16 |
| 10 | 3.170979e-16 |
| 25 | 7.927448e-16 |
| 50 | 1.585490e-15 |
| 100 | 3.170979e-15 |

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.
A millennium is a unit of time equal to 1,000 years, or approximately 365,250 days (31,536,000,000 seconds based on 365-day years).
1 millennium = 1,000 years = 100 decades = 10 centuries ≈ 365,250 average days.
To convert millennia to years: multiply by 1,000. To centuries: multiply by 10.
Archaeological dating, geological time references, long-term environmental projections, and civilization-scale history.
The 'Y2K bug' at the turn of the millennium cost an estimated $300 billion to fix worldwide. Writing was invented about 5 millennia ago.
Like centuries, the 3rd millennium began Jan 1, 2001, not 2000 — though the popular celebration was in 2000.
Think of milestones: ~10 ka = agriculture, ~5 ka = writing, ~2.5 ka = classical civilizations, ~0.5 ka = printing press.
