About Converting Picoseconds to Attoseconds
Picosecond and Attosecond 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 attosecond is 1e-18 second units.
Formula
attoseconds = picoseconds × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 picosecond equals 1e-12 base units, and 1 attosecond equals 1e-18 base units, so dividing one by the other gives the direct picosecond-to-attosecond factor of 1000000.
Simple example
1 ps × 1000000 = 1,000,000 as
1 picosecond = 1,000,000 attoseconds.
Real-world example
24 ps × 1000000 = 24,000,000 as
24 picoseconds = 24,000,000 attoseconds.

Reverse conversion: Attosecond to Picosecond
1 as × 0.000001 = 0.000001 ps
1 attosecond = 0.000001 picoseconds.
picoseconds = attoseconds × 0.000001

Frequently asked questions
How many attoseconds are in 1 picosecond?
1 picosecond equals 1,000,000 attoseconds, using the exact defined conversion factor rather than an estimate.
How do I convert picosecond to attosecond?
Multiply the picosecond value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert attosecond back to picosecond?
Use the reverse factor: 1 attosecond equals 0.000001 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 attosecond?
Attosecond (as) is a unit of time.
Is the picosecond to attosecond conversion exact?
Yes. Both picosecond and attosecond are defined by fixed standards rather than physical artifacts, so the factor of 1000000 used above is exact to as many digits as you choose to display.
