What Is This Tool?
This tool enables conversion of time units from attoseconds (as) to femtoseconds (fs), helping users translate ultra-short durations used in ultrafast science, femtochemistry, and laser pulse analysis into a more common time unit.
How to Use This Tool?
-
Enter a numerical value representing attoseconds in the input field
-
Select attosecond as the input unit and femtosecond as the output unit
-
Click the convert button to see the equivalent femtosecond value
-
