Convert Megayears to Nanoseconds
Convert Megayears (Ma) to Nanoseconds (ns) instantly and accurately.
Conversion Formula
ns = Ma × 3.155695200e+22
About Megayears
A megayear (1 Ma) = 10⁶ yr ≈ 3.156 × 10¹³ s - the timescale of geology and tectonic evolution. The K-Pg mass extinction at 66.0 Ma; Cambrian explosion ~538.8 Ma; Great Oxygenation Event ~2,400 Ma. Plate motion at 2-10 cm/yr = 200-1,000 km per Ma (Atlantic ~3,000 km wider since Pangaea rifting ~200 Ma ago). Background extinction rate measured in extinctions per million species-years. 1 Ma = 10⁶ yr.
About Nanoseconds
A nanosecond (ns) = 10⁻⁹ s; light travels ~30 cm - Grace Hopper distributed 30 cm wire segments as physical 'nanoseconds' to illustrate latency. CPU clock cycles at 3-5 GHz: 0.2-0.33 ns. DDR5 CAS latency ~10 ns. GPS requires <3 ns timing accuracy for sub-metre positioning. Lightning return strokes rise in 100-200 ns. Data-centre 400GbE switch latency 300-500 ns. 1 ns = 10⁻⁹ s.
