How to Convert Hertz to Petahertz
To convert hertz to petahertz, multiply the frequency by the following conversion ratio: 1e-15 petahertz/hertz.
Since one hertz is equal to 1e-15 petahertz, you can use this simple formula to convert:
The frequency in petahertz is equal to the frequency in hertz multiplied by 1e-15.
For example, here's how to convert 5 hertz to petahertz using the formula above.
How Many Petahertz Are in a Hertz?
There are 1e-15 petahertz in a hertz, which is why we use this value in the formula above.
Our hertz to petahertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Hertz and petahertz are both units used to measure frequency. Keep reading to learn more about each unit.
What Is a Hertz?
SI unit of frequency equal to 1 cycle per second. It serves as a primary reference unit for measuring frequency across scientific and practical applications. [1]
The hertz is classified as an International System of Units (SI) unit of frequency. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.
As the primary coherent reference unit for frequency in this category, all other frequency units are mathematically anchored to the hertz (Hz).
In practice, hertz (Hz) are widely used across standard frequency applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Petahertz?
A petahertz is a unit of frequency equal to 1e+15 hertz (Hz), the base unit for frequency. Equal to 10¹⁵ Hz. [2]
The petahertz is classified as an International System of Units (SI) unit of frequency. Petahertz can be abbreviated as PHz; for example, 1 petahertz can be written as 1 PHz.
In the metric system, "peta" is the standard SI prefix for quadrillions, or 10¹⁵. This makes the petahertz (PHz) a convenient decimal multiple of the hertz (Hz).
In practice, petahertz (PHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting frequency between hertz (Hz) and petahertz (PHz), keep full floating-point precision (1 Hz = 1e-15 PHz; 1 PHz = 1e+15 Hz) during intermediate calculations and round only the final petahertz figure to match your instrument tolerance.
