About Converting Picoseconds to Femtoseconds
Picosecond and Femtosecond are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Specifically: Picosecond is 1e-12 second units, and femtosecond is 1e-15 second units.
Formula
femtoseconds = picoseconds × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 picosecond equals 1e-12 base units, and 1 femtosecond equals 1e-15 base units, so dividing one by the other gives the direct picosecond-to-femtosecond factor of 1000.
Simple example
1 ps × 1000 = 1,000 fs
1 picosecond = 1,000 femtoseconds.
Real-world example
24 ps × 1000 = 24,000 fs
24 picoseconds = 24,000 femtoseconds.

| 7 ps | 7,000 fs |
| 24 ps | 24,000 fs |
| 30 ps | 30,000 fs |
| 100 ps | 100,000 fs |
| 365 ps | 365,000 fs |
Reverse conversion: Femtosecond to Picosecond
1 fs × 0.001 = 0.001 ps
1 femtosecond = 0.001 picoseconds.
picoseconds = femtoseconds × 0.001

Frequently asked questions
How many femtoseconds are in 1 picosecond?
1 picosecond equals 1,000 femtoseconds, using the exact defined conversion factor rather than an estimate.
How do I convert picosecond to femtosecond?
Multiply the picosecond value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert femtosecond back to picosecond?
Use the reverse factor: 1 femtosecond equals 0.001 picoseconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a picosecond?
Picosecond (ps) is a unit of time.
What is a femtosecond?
Femtosecond (fs) is a unit of time.
Is the picosecond to femtosecond conversion exact?
Yes. Both picosecond and femtosecond are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
