About Converting Picoseconds to Gigaseconds
Picosecond and Gigasecond 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 gigasecond is 1000000000 second units.
Formula
gigaseconds = picoseconds × 1e-21
This factor comes from each unit's defined relationship to the category's base unit: 1 picosecond equals 1e-12 base units, and 1 gigasecond equals 1000000000 base units, so dividing one by the other gives the direct picosecond-to-gigasecond factor of 1e-21.
Simple example
1 ps × 1e-21 = 1e-21 Gs
1 picosecond = 1e-21 gigaseconds.
Real-world example
24 ps × 1e-21 = 2.4e-20 Gs
24 picoseconds = 2.4e-20 gigaseconds.

Reverse conversion: Gigasecond to Picosecond
1e-21 Gs × 1e+21 = 1 ps
1e-21 gigaseconds = 1 picosecond.
picoseconds = gigaseconds × 1e+21

Frequently asked questions
How many gigaseconds are in 1 picosecond?
1 picosecond equals 1e-21 gigaseconds, using the exact defined conversion factor rather than an estimate.
How do I convert picosecond to gigasecond?
Multiply the picosecond value by 1e-21. The converter above does this instantly to whatever precision you set.
How do I convert gigasecond back to picosecond?
Use the reverse factor: 1 gigasecond equals 1e+21 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 gigasecond?
Gigasecond (Gs) is a unit of time.
Is the picosecond to gigasecond conversion exact?
Yes. Both picosecond and gigasecond are defined by fixed standards rather than physical artifacts, so the factor of 1e-21 used above is exact to as many digits as you choose to display.
