Millisecond (ms). A millisecond is one thousandth of a second, used for reaction times and computer timing.
Attosecond (as). An attosecond is 10⁻¹⁸ of a second, the scale of electron motion in atoms.
There are 1 × 10¹⁵ attoseconds in one millisecond.
Multiply the number of milliseconds by 1 × 10¹⁵. For example, 10 milliseconds equal 1 × 10¹⁶ attoseconds.
One attosecond equals 1 × 10⁻¹⁵ milliseconds.
1.2 × 10¹⁶ attoseconds. Other common values: 5 milliseconds = 5 × 10¹⁵ attoseconds and 100 milliseconds = 1 × 10¹⁷ attoseconds.
