⚡ Nanoseconds to Gigaseconds: the quick answer

1 ns = 1 × 10⁻¹⁸ Gs 1 nanosecond equals 1 × 10⁻¹⁸ gigaseconds

To convert nanoseconds to gigaseconds, multiply the value by 1 × 10⁻¹⁸. To go the other way, multiply gigaseconds by 1 × 10¹⁸ to get nanoseconds.

↔ Convert gigaseconds to nanoseconds instead

🧮 Formula

Nanoseconds to Gigaseconds
Gs = ns × 1 × 10⁻¹⁸
Gigaseconds to Nanoseconds
ns = Gs × 1 × 10¹⁸

Where

  • ns = the time in nanoseconds
  • Gs = the time in gigaseconds
Every unit here is defined by its time in seconds, so the conversion factor is (seconds per nanosecond) ÷ (seconds per gigasecond).
