Why is erg/second used if it is such a small unit?

Erg per second is commonly used in astrophysics and theoretical calculations where CGS units are standard, especially when dealing with small-scale power values.

What kind of applications use petajoule/second as a unit?

Petajoule per second is used to describe extremely large-scale power flows, such as national energy outputs, planetary power budgets, or combined outputs of many power plants.

Can I use this conversion tool for daily engineering purposes?

Due to the vast difference in unit scale, this conversion is generally not practical for everyday engineering or smaller-scale power measurements.

What Is This Tool?

This converter allows you to change power measurements from the CGS-system unit erg per second (erg/s) to the extremely large-scale SI unit petajoule per second (PJ/s). It is useful for translating small-scale astrophysical power values into large-scale energy flow measurements.

How to Use This Tool?

Enter the power value in erg/second (erg/s).
Select erg/second as the source unit and petajoule/second as the target unit.
Click convert to see the equivalent power value in petajoule/second (PJ/s).

Key Features

Converts power units from erg/second to petajoule/second with a precise conversion factor.
Supports astrophysics and theoretical calculations involving CGS and SI power units.
Provides examples to illustrate unit conversion results on vastly different scales.

Examples

Converting 1 × 10⁷ erg/s yields 1 × 10⁻¹⁵ PJ/s.
Converting 5 × 10¹⁰ erg/s yields 5 × 10⁻¹² PJ/s.

Common Use Cases

Expressing luminosities of stars and radiative power of astronomical sources in astrophysics.
Reporting power in theoretical and older scientific literature using CGS units.
Describing large-scale energy flows for planetary or national energy assessments.
Comparing the output of multiple power plants or vast infrastructure capacities.

Tips & Best Practices

Ensure input values are in erg/second before converting to maintain accuracy.
Use this conversion for astrophysical or large-scale power data rather than everyday engineering values.
Leverage the tool to bridge CGS-based theoretical units with SI units common in energy policy and science.

Limitations

The conversion results in very small decimal values, limiting practical use in daily engineering tasks.
Erg/second is a CGS unit primarily used in theoretical contexts and is less compatible with modern SI standards.
Not suitable for applications needing straightforward interpretation of common power scales.
