This converter allows you to convert attoseconds [as] to nanoseconds [ns] or nanoseconds [ns] to attoseconds [as]. 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 attosecond [as] = 10-9 nanoseconds [ns]1 nanosecond [ns] = 109 attoseconds [as]

Convert attoseconds to nanoseconds

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

  • Nanoseconds [ns] = attoseconds [as] ÷ 109
  • Nanoseconds [ns] = attoseconds [as] * 10-9

Convert nanoseconds to attoseconds

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

  • Attoseconds [as] = nanoseconds [ns] * 109
  • Attoseconds [as] = nanoseconds [ns] ÷ 10-9
