About Converting Revolutions per second to Radians per second
Revolutions per second 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: Revolutions per second, and angular frequency converted by one revolution equals 2*pi radians.
Formula
radians per second = revolutions per second × 6.28318530718
This factor comes from each unit's defined relationship to the category's base unit: 1 revolutions per second equals 1 base unit, and 1 radians per second equals 0.159154943092 base units, so dividing one by the other gives the direct revolutions per second-to-radians per second factor of 6.28318530718.
Simple example
1 rps × 6.283185307 = 6.283185307 rad/s
1 revolutions per second = 6.283185307 radians per second.
Real-world example
10 rps × 6.283185307 = 62.83185307 rad/s
10 revolutions per second = 62.83185307 radians per second.

Frequently asked questions
How many radians per second are in 1 revolutions per second?
1 revolutions per second equals 6.283185307 radians per second, using the exact defined conversion factor rather than an estimate.
How do I convert revolutions per second to radians per second?
Multiply the revolutions per second value by 6.283185307. The converter above does this instantly to whatever precision you set.
How do I convert radians per second back to revolutions per second?
Use the reverse factor: 1 radians per second equals 0.1591549431 revolutions per second. You can also use the swap control in the converter above to flip the direction instantly.
What is a revolutions per second?
Revolutions per second (rps) 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 revolutions per second to radians per second conversion exact?
Yes. Both revolutions per second and radians per second are defined by fixed standards rather than physical artifacts, so the factor of 6.283185307 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.
