Nanoseconds to Seconds Converter

1 nanosecond (ns) equals 1 × 10-9 seconds (s).

Quick answer

  • 1 nanosecond = 1 × 10-9 seconds
  • 1 second = 1,000,000,000 nanoseconds
  • Formula: s = ns × 1 × 10-9

1 nanosecond = 1 × 10-9 seconds

How to convert nanoseconds to seconds

s = ns × 1 × 10-9

To convert nanoseconds to seconds, multiply the number of nanoseconds by 1 × 10-9.

Example: 18 ns to s

  1. Start with the value in nanoseconds: 18 ns.
  2. Multiply by 1 × 10-9: 18 × 1 × 10-9 = 1.8 × 10-8.
  3. Result: 18 nanoseconds = 1.8 × 10-8 seconds.

Going the other way, 1 second = 1,000,000,000 nanoseconds, so to convert seconds back to nanoseconds you divide by the same number. See seconds to nanoseconds.
