1 E13 s

To help compare orders of magnitude of different times this page lists times between 320 000 years and 3 200 000 years (1013 seconds and 1014 seconds) See also times of other orders of magnitude.


 * Shorter times
 * 340,000 years -- half-life of curium-248
 * 379 000 years -- time after the Big Bang until cosmic microwave background radiation began
 * 500 000 years -- time since the colonisation of Eurasia by Homo erectus
 * ~700,000 years -- time since last reversal of earth's magnetic field
 * 790 000 years -- age of the earliest evidence of the controlled use of fire by Homo erectus
 * 1,000,000 years -- the average lifespan of a blue supergiant star
 * 1,500,000 years -- time since beginning of Pleistocene Epoch (beginning of Quaternary Period)
 * 1,500,000 years -- time since end of Pliocene Epoch (end of Tertiary Period)
 * 1,530,000 years -- half-life of zirconium-93
