One billionth of one second 1 ns: The time needed to execute one machine cycle by a 1 GHz microprocessor 1 ns: The time light takes to travel 30 cm (11.811 in) 10 −6: microsecond: μs One millionth of one second 1 μs: The time needed to execute one machine cycle by an Intel 80186 microprocessor 2.2 μs: The lifetime of a muon
In standard form, it is written as 1 × 10 9. The metric prefix giga indicates 1,000,000,000 times the base unit. Its symbol is G. One billion years may be called an eon in astronomy or geology. Previously in British English (but not in American English), the word "billion" referred exclusively to a million millions (1,000,000,000,000). However ...
The universe has appeared much the same as it does now, for many billions of years. It will continue to look similar for many more billions of years into the future. The galactic disk of the Milky Way is estimated to have been formed 8.8 ± 1.7 billion years ago but only the age of the Sun, 4.567 billion years, is known precisely. [79]
One hundredth of a second. decisecond: 10 −1 s: One tenth of a second. second: 1 s: SI base unit for time. decasecond: 10 s: Ten seconds (one sixth of a minute) minute: 60 s: hectosecond: 100 s: milliday: 1/1000 d (0.001 d) 1.44 minutes, or 86.4 seconds. Also marketed as a ".beat" by the Swatch corporation. moment: 1/40 solar hour (90 s on ...
One second after 2038-01-19T03:14:07Z this representation will overflow in what is known as the year 2038 problem. In some newer operating systems, time_t has been widened to 64 bits. This expands the times representable to about 292.3 billion years in both directions, which is over twenty times the present age of the universe.
One billion or 10 9 years. Cosmology and geology. [39] For example, the formation of the Earth occurred approximately 4.54 Ga (4.54 billion years) ago and the age of the universe is approximately 13.8 Ga. Ta (for teraannus) One trillion or 10 12 years: An extremely long unit of time, about 70 times as long as the age of the universe.
More precisely, a billion seconds is exactly 31 years, 8 months, 2 weeks, 1 day, 17 hours, 46 minutes, and 40 seconds. Does this allow for leap years? — Arthur Rubin 09:28, 14 May 2019 (UTC) I am guessing not because the number of leap days will vary over the duration. Years, months and weeks should ideally be converted into weeks.
