This converter allows you to convert seconds [s] to nanoseconds [ns] or nanoseconds [ns] to seconds [s]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 second [s] = 109 nanoseconds [ns]1 nanosecond [ns] = 10-9 seconds [s]

Convert seconds to nanoseconds

There are two simple ways to convert seconds [s] to nanoseconds [ns]. In the first calculation method, the value in seconds [s] is divided by 10-9. The second method multiplies the value in seconds [s] by 109.

  • Nanoseconds [ns] = seconds [s] ÷ 10-9
  • Nanoseconds [ns] = seconds [s] * 109

Convert nanoseconds to seconds

Converting nanoseconds [ns] to seconds [s] is easy and can be done in two ways. The first method involves multiplication, whereby the value in nanoseconds [ns] is multiplied by 10-9. The second variant is a division. Here, the value in nanoseconds [ns] is divided by 109.

  • Seconds [s] = nanoseconds [ns] * 10-9
  • Seconds [s] = nanoseconds [ns] ÷ 109
