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) = 3.162315e-14 Year (Leap) (yr (Leap)).
| Microsecond (µs) | Year (Leap) (yr (Leap)) |
|---|---|
| 0.1 | 3.162315e-15 |
| 0.5 | 1.581158e-14 |
| 1 | 3.162315e-14 |
| 2 | 6.324631e-14 |
| 5 | 1.581158e-13 |
| 10 | 3.162315e-13 |
| 25 | 7.905788e-13 |
| 50 | 1.581158e-12 |
| 100 | 3.162315e-12 |
| 500 | 1.581158e-11 |

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 leap year is a calendar year containing 366 days (31,622,400 seconds), with an extra day added as February 29th to correct calendar drift.
1 leap year = 366 d = 8,784 h = 527,040 min = 31,622,400 s. That's 86,400 s more than a common year.
To convert leap years to days: multiply by 366. To seconds: multiply by 31,622,400.
Calendar systems, date arithmetic in software (handling Feb 29), birthday celebrations for 'leaplings,' and financial calculations.
People born on February 29 are called 'leaplings' — they technically have a birthday only once every 4 years. The odds of being born on Feb 29 are about 1 in 1,461.
The most common bug: not handling Feb 29. Many software failures have occurred on leap day. Also, the 100/400 rule is often forgotten.
Leap year test: divisible by 4? Yes → leap year, UNLESS divisible by 100, UNLESS also divisible by 400. Code it: (y%4==0 && y%100!=0) || y%400==0.
