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-16 Century (cen).

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 century is a unit of time equal to 100 years, or approximately 36,525 days (3,153,600,000 seconds based on 365-day years).
1 century = 100 years = 10 decades = 1,200 months ≈ 36,525 average days.
To convert centuries to years: multiply by 100. To decades: multiply by 10.
Historical periodization, infrastructure planning (century-old bridges), and long-term climate projections.
The Gregorian calendar gained only about 1 day of error per 3,236 years — meaning it stays accurate for centuries without adjustment.
The 21st century began on January 1, 2001 — not 2000. There was no year 0, so the first century was years 1–100.
Century numbering: the 1900s = 20th century. Add 1 to the hundreds: 1800s = 19th century, 2000s = 21st century.
