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
1.1–1.2×10 14 (110–120 trillion) The time by which all stars in the universe will have exhausted their fuel (the longest-lived stars, low-mass red dwarfs, have lifespans of roughly 10–20 trillion years). [9] After this point, the stellar-mass objects remaining are stellar remnants (white dwarfs, neutron stars, black holes) and brown dwarfs.
One billion or 10 9 years. Cosmology and geology [38] 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.
An analogy from a 1986 New York Times article helps put it into perspective: a million seconds is almost 12 days, a billion seconds is about 31.7 years, and a trillion seconds is about 31,709.8 years.
A picosecond (abbreviated as ps) is a unit of time in the International System of Units (SI) equal to 10 −12 or 1 ⁄ 1 000 000 000 000 (one trillionth) of a second. That is one trillionth, or one millionth of one millionth of a second, or 0.000 000 000 001 seconds. A picosecond is to one second, as one second is to approximately 31,688.76 years.
31688 = the number of years approximately equal to 1 trillion seconds; 31721 = start of a prime quadruplet [7] 31929 = Zeisel number [8] 32000 to 32999.
