About Converting Attoseconds to Picoseconds
Attosecond and Picosecond 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: Attosecond is 1e-18 second units, and picosecond is 1e-12 second units.
Formula
picoseconds = attoseconds × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 attosecond equals 1e-18 base units, and 1 picosecond equals 1e-12 base units, so dividing one by the other gives the direct attosecond-to-picosecond factor of 0.000001.
Simple example
1 as × 0.000001 = 0.000001 ps
1 attosecond = 0.000001 picoseconds.
Real-world example
24 as × 0.000001 = 0.000024 ps
24 attoseconds = 0.000024 picoseconds.

Frequently asked questions
How many picoseconds are in 1 attosecond?
1 attosecond equals 0.000001 picoseconds, using the exact defined conversion factor rather than an estimate.
How do I convert attosecond to picosecond?
Multiply the attosecond value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert picosecond back to attosecond?
Use the reverse factor: 1 picosecond equals 1,000,000 attoseconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a attosecond?
Attosecond (as) is a unit of time.
What is a picosecond?
Picosecond (ps) is a unit of time.
Is the attosecond to picosecond conversion exact?
Yes. Both attosecond and picosecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
