petahertz to microhertz
Convert petahertz (PHz) to microhertz (μHz). Use an editable frequency converter, conversion formula, and reference table.
1 PHz = 1e+21 μHz
Conversion formula
One petahertz equals 1e+21 microhertz. Multiply your value in petahertz by this factor to get microhertz. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 petahertz:5 × 1e+21 = 5e+21 μHz

About these measurements
Frequency measures cycles per second.
The base reference used here is the hertz. One petahertz is 1e+15 base units; one microhertz is 0.000001 base units.
Important distinctions
Frequency is the reciprocal of period, not angular velocity.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert PHz to μHz?
Multiply the quantity in PHz by 1e+21. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the microhertz to petahertz converter.
