Nanoseconds to femtosecond Conversion
1 nanoseconds (ns) is equal to 1000000 femtosecond (fsec).
1 ns = 1000000 fsec
or
1 fsec = 0.000001 ns
Formula
To convert a time from nanoseconds (ns) to femtosecond (fsec), multiply the time in nanoseconds by 1000000
t(fsec) = t(ns) × 1000000
Examples:
Convert 15 nanoseconds to femtosecond:
t(fsec) = 15ns × 1000000 = 15000000 fsec

Frequently asked questions
How do I convert nanoseconds to femtosecond?
Multiply the value in nanoseconds by 1000000 to get the result in femtosecond. For example, 5 ns × 1000000 = 5000000 fsec.
How many femtosecond are in 1 nanoseconds?
1 nanoseconds (ns) is equal to 1000000 femtosecond (fsec).
How do I convert femtosecond back to nanoseconds?
Use the inverse operation: divide the value in femtosecond by 1000000 to get the result in nanoseconds.
How accurate is the nanoseconds to femtosecond conversion?
The converter multiplies by the conversion factor 1000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
