Conversion Formula
Ga = t_P × 1.708418164e-60
About Planck Time
The Planck time (t_P) = √(ℏG/c⁵) ≈ 5.391 × 10⁻⁴⁴ s — the time for light to travel one Planck length (~1.616 × 10⁻³⁵ m). Below this scale, general relativity and quantum mechanics both break down; a theory of quantum gravity is needed. No physical process or instrument approaches this timescale — it is a theoretical lower bound. Introduced by Max Planck in 1899. 1 t_P ≈ 5.391 × 10⁻⁴⁴ s.
About Gigayears
A gigayear (1 Ga) = 10⁹ yr ≈ 3.156 × 10¹⁶ s - the timescale of stellar evolution and cosmology. Universe age: 13.787 ± 0.020 Ga (Planck CMB). Sun: 4.603 Ga old; red giant in ~5 Ga. A 0.1 M☉ red dwarf lives ~10,000 Ga. Uranium-238 half-life = 4.468 Ga (used in radiometric dating). Proton decay (GUT prediction): ~10³⁴ yr = ~10²⁵ Ga. 1 Ga = 10⁹ yr.
