Decades to Nanoseconds (dec to ns)
1 decade equals 3.1556952×10¹⁷ nanoseconds exactly.
How to convert decades to nanoseconds
To convert decades to nanoseconds, multiply the number of decades by 3.1556952×10¹⁷. This factor is exact. To go the other way, multiply nanoseconds by 3.168873851×10⁻¹⁸ (rounded).
nanoseconds = decades × 3.1556952×10¹⁷
Example: 10 decades = 3.1556952×10¹⁸ nanoseconds.
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).

Nanosecond (ns)
One billionth of a second. Light travels about 30 cm in a nanosecond.
Few units are as easy to picture as the nanosecond, because light makes it concrete. In a vacuum, light needs about 3.34 nanoseconds to travel one metre and about 1.02 nanoseconds to travel one foot. That is why engineers talk about wire lengths and signal delays in the same breath once clocks reach the gigahertz range, where the cycle time of a 1 GHz signal is exactly one nanosecond.
A nanosecond is one billionth of a second, and the ratio is hard to grasp: one nanosecond is to one second as one second is to about 31.7 years. It is the natural unit of fast digital hardware. A 74HC-series logic chip common in the mid-1980s had a typical propagation delay of about 8 ns, and the gap between packets on Gigabit Ethernet is 96 ns. The Go language's time package offers 1 ns precision.
1 nanosecond = 1×10⁻⁹ seconds (exactly).
