What does 1 hertz represent?

One hertz denotes one cycle per second and is the standard unit measuring frequency.

Why use picohertz instead of hertz?

Picohertz is used to express extremely low frequencies occurring over very long periods, which are inconvenient to represent directly in hertz.

What kind of phenomena are measured in picohertz?

Picohertz measures ultra-low-frequency events such as Milankovitch climate cycles and certain astrophysical time scales.

What Is This Tool?

This converter allows you to convert frequency values from hertz (Hz), the standard SI unit representing cycles per second, into picohertz (pHz), which measures extremely low frequencies common in geophysical and astrophysical studies.

How to Use This Tool?

Enter the frequency value in hertz that you want to convert
Select 'hertz [Hz]' as the input unit and 'picohertz [pHz]' as the output unit
Click the convert button to see the result in picohertz
Use the result to analyze low-frequency cycles in geophysical or astrophysical contexts

Key Features

Converts frequency between hertz and picohertz units accurately
Supports analysis of ultra-low-frequency oscillations over very long timescales
Includes example calculations for quick reference
Browser-based and easy to use

Examples

Convert 2 Hz: 2 × 1,000,000,000,000 = 2,000,000,000,000 pHz
Convert 0.5 Hz: 0.5 × 1,000,000,000,000 = 500,000,000,000 pHz

Common Use Cases

Studying orbital-driven climate cycles lasting tens to hundreds of thousands of years
Analyzing Earth's axial precession with a period around 26,000 years
Examining very-long-period astrophysical or cosmological signals and dynamics

Tips & Best Practices

Ensure the frequency value is appropriate for conversion to ultra-low frequency units
Interpret converted results within the physical context of very long timescale oscillations
Use this conversion primarily for geophysical and astrophysical applications, not for high or everyday frequencies

Limitations

Picohertz values represent extremely long periodicities, unsuitable for typical or high-frequency applications
Results must be carefully interpreted to avoid confusion outside ultra-low-frequency contexts
