About Converting Femtohertz to Revolutions per second
Femtohertz and Revolutions per second both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Femtohertz is 1e-15 hertz units, and revolutions per second.
Formula
revolutions per second = femtohertz × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 femtohertz equals 1e-15 base units, and 1 revolutions per second equals 1 base unit, so dividing one by the other gives the direct femtohertz-to-revolutions per second factor of 1e-15.
Simple example
1 fHz × 1e-15 = 1e-15 rps
1 femtohertz = 1e-15 revolutions per second.
Real-world example
1,000 fHz × 1e-15 = 1e-12 rps
1,000 femtohertz = 1e-12 revolutions per second.

Reverse conversion: Revolutions per second to Femtohertz
1e-15 rps × 1e+15 = 1 fHz
1e-15 revolutions per second = 1 femtohertz.
femtohertz = revolutions per second × 1e+15

Frequently asked questions
How many revolutions per second are in 1 femtohertz?
1 femtohertz equals 1e-15 revolutions per second, using the exact defined conversion factor rather than an estimate.
How do I convert femtohertz to revolutions per second?
Multiply the femtohertz value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert revolutions per second back to femtohertz?
Use the reverse factor: 1 revolutions per second equals 1e+15 femtohertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtohertz?
Femtohertz (fHz) is a unit of frequency.
What is a revolutions per second?
Revolutions per second (rps) is a unit of frequency.
Is the femtohertz to revolutions per second conversion exact?
Yes. Both femtohertz and revolutions per second are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 used above is exact to as many digits as you choose to display.
