About Converting Petahertz to Radians per second
Petahertz and Radians per second are both scientific-measurement units, spanning everything from atomic and laboratory scales to astronomical distances — the kind of conversion that comes up constantly in physics, chemistry, and astronomy when a result needs to move between conventions used in different subfields. Specifically: Petahertz is 1000000000000000 hertz units, and angular frequency converted by one revolution equals 2*pi radians.
Formula
radians per second = petahertz × 6.283185e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 petahertz equals 1e+15 base units, and 1 radians per second equals 0.159154943092 base units, so dividing one by the other gives the direct petahertz-to-radians per second factor of 6.283185e+15.
Simple example
1 PHz × 6.283185e+15 = 6.283185e+15 rad/s
1 petahertz = 6.283185e+15 radians per second.
Real-world example
10 PHz × 6.283185e+15 = 6.283185e+16 rad/s
10 petahertz = 6.283185e+16 radians per second.

Frequently asked questions
How many radians per second are in 1 petahertz?
1 petahertz equals 6.283185e+15 radians per second, using the exact defined conversion factor rather than an estimate.
How do I convert petahertz to radians per second?
Multiply the petahertz value by 6.283185e+15. The converter above does this instantly to whatever precision you set.
How do I convert radians per second back to petahertz?
Use the reverse factor: 1 radians per second equals 1.591549e-16 petahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a petahertz?
Petahertz (PHz) is a unit of scientific units.
What is a radians per second?
Radians per second (rad/s) is a unit of scientific units.
Is the petahertz to radians per second conversion exact?
Yes. Both petahertz and radians per second are defined by fixed standards rather than physical artifacts, so the factor of 6.283185e+15 used above is exact to as many digits as you choose to display.
Why does this category span everything from atomic to astronomical scales?
Scientific work spans an enormous range of physical scales, from atomic distances (measured in angstroms or atomic mass units) to interstellar distances (measured in astronomical units or parsecs), so this category groups SI-derived and scale-specific units that researchers commonly need to convert between within their field.
