Decades to Microseconds (dec to µs)
1 decade equals 315,569,520,000,000 microseconds exactly.
How to convert decades to microseconds
To convert decades to microseconds, multiply the number of decades by 315,569,520,000,000. This factor is exact. To go the other way, multiply microseconds by 3.168873851×10⁻¹⁵ (rounded).
microseconds = decades × 315,569,520,000,000
Example: 10 decades = 3.1556952×10¹⁵ microseconds.
Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.
About these units
Decade (dec)
Ten years.
Greek dekas, a group of ten, gave English decade, and the Latin equivalent decennium survives in words like decennial. The idea of naming whole decades is newer. The convention of grouping years by their tens digit, so that 1960 to 1969 is the 1960s, became common in the late 19th century, and the 20th century then produced a gallery of nicknames such as the Roaring Twenties and the Swinging Sixties.
A decade is ten years, which on this site means ten average Gregorian years. The two counting styles can disagree, in the same way as with centuries: since the AD calendar has no year zero, a strict reading makes the first decade run from year 1 to year 10. A 2019 YouGov poll of 13,582 US adults found 64 percent expected the next decade to be 2020 to 2029, 17 percent said 2021 to 2030, and 19 percent did not know. Most people prefer the zero-to-nine version.
1 decade = 315,569,520 seconds (exactly).

Microsecond (µs)
One millionth of a second. Used for electronics and processor timing.
Writing a microsecond takes a Greek letter, mu, which stands for the prefix micro-, one millionth. Where plain text cannot display it, people fall back on the letter u and write us. The unit belongs to electronics and radio: a signal that repeats every microsecond has a frequency of 1 MHz, and a radio wave of that period is about 300 m long.
A microsecond is one millionth of a second, short enough that light in a vacuum crosses only about 1 km in 3.34 of them. Digital audio lives on this scale, because a CD sample at 44.1 kHz lasts about 22.7 microseconds and a 48 kHz sample about 20.8. A modern solid-state drive has an access latency of about 50 microseconds, and a camera flash lasts around 1,000. Relativity matters at this scale too: GPS satellite clocks would drift by about 38 microseconds per day without compensation. Wikipedia notes that the 2011 Japanese earthquake shortened the day by about 1.8 microseconds.
1 microsecond = 0.000001 seconds (exactly).
