A gigasecond (symbol: Gs) is 1 billion seconds, or roughly 31.558 years. Below is a table that lists times of between 1 and 1000 gigaseconds, or between 31.558 and 31,558 years. This timescale encompasses the whole of human history since the time of Cro-Magnon man. * Shorter times ==1–10 gigaseconds== * 1.11 Gs (35 years) – Constitutionally-mandated minimum age for President of the United States * 1.14 Gs (36 years) – recorded maximum lifespan of a cat * 1.60 Gs (50.5 years) – average age of human menopause * 1.65 Gs (52 years) – length of one calendar round in the Mesoamerican calendar * 1.90 Gs (60 years) – length of one full cycle (Celestial stem/Terrestrial branch) in the Chinese calendar * 2.017 Gs (63 years), 8 months – Reign of Queen Victoria * 2.03 Gs (64 years) – Reign of the Pharaoh Rameses II * 2.06 Gs (65 years) – a common age for retirement of workers * 2.147483647 Gs (68.056118 years) – length of the 32-bit Unix epoch, which ends on Jan 19, 2038. * 2.29 Gs (72 years, 3 months, 18 days) – reign of Louis XIV * 2.35 Gs (74 years) – duration of Communist rule in Russia * 2.38 Gs (75 years) – average life span of humans in the First World * 2.47 Gs (78 years) – estimated maximum lifespan of an elephant * 2.671 Gs (84.3 years) – one orbit of Uranus * 3.1688 Gs (100 years) – one century. Approximate duration of the Inca Empire * 3.68 Gs (116 years) – duration of the Hundred Years War * 3.8802 Gs (122 years and 164 days) – longest recorded lifespan of any known human (Jeanne Calment) * 5.229 Gs (165 years) – one orbit of Neptune * 6.02 Gs (190 years) – credited age of the oldest known tortoise, oldest land animal * 7.849 Gs (247.7 years) – one orbit of Pluto * 8.974 Gs (283.2 years) – one orbit of Haumea * 9.13 Gs (288 years) – one orbit of Quaoar * 9.57 Gs (302 years) – duration of Spanish colonial rule in Mexico * 9.63 Gs (304 years) – duration of the Romanov dynasty in Russia * 9.79 Gs (309 years) – one orbit of Makemake 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gigasecond」の詳細全文を読む スポンサード リンク
