What Is This Tool?
This tool allows you to convert power values from attojoule per second, a unit measuring extremely small rates of energy transfer in SI, to erg per second, a CGS unit commonly used in astrophysics and older scientific references.
How to Use This Tool?
-
Enter the power value in attojoule per second (aJ/s)
-
Select attojoule/second as the source unit
-
Choose erg/second as the target unit
-
Click convert to get the equivalent power in erg per second (erg/s)
-
Review and use the converted value for your scientific or technical needs
Key Features
-
Converts between attojoule/second [aJ/s] and erg/second [erg/s]
-
Based on the precise conversion factor: 1 aJ/s = 1e-11 erg/s
-
Supports translation from extremely small SI power units to CGS units
-
Useful for quantum sensing, nanoscale thermal metrology, and astrophysics
-
Browser-based and easy to use without installation
Examples
-
Convert 5 aJ/s to erg/s results in 5e-11 erg/s
-
Convert 10 aJ/s to erg/s results in 1e-10 erg/s
Common Use Cases
-
Characterizing ultra-low-power consumption in microelectronic sensors and IoT devices
-
Measuring power transfer rates in quantum and nanoscale devices like single-photon detectors
-
Reporting radiative power and luminosity of astronomical bodies in astrophysics
-
Facilitating theoretical calculations using CGS units in older scientific literature
-
Quantifying tiny heat flow rates in cryogenic and nanoscale thermal experiments
Tips & Best Practices
-
Ensure correct unit selection to maintain accuracy
-
Use the exact conversion factor provided to avoid calculation errors
-
Double-check small numerical results due to very small scale of attojoule/second
-
Apply converted values in context-specific scientific or engineering tasks
-
Be aware of the difference in unit systems (SI vs CGS) when interpreting results
Limitations
-
Conversion results in very small numbers because attojoule/second represents extremely low power levels
-
Care must be taken to maintain numerical precision and avoid rounding errors
-
Differences in unit systems may require cautious interpretation in some contexts

Key Terminology
-
Attojoule/second (aJ/s)
-
A unit of power equal to 10^-18 joules transferred per second used for very small energy transfer rates.
-
Erg/second (erg/s)
-
A CGS unit of power equal to one erg transferred each second; equivalent to 1×10⁻⁷ watt in SI units.
-
Conversion Factor
-
The numerical ratio used to translate a value from one unit to another; here, 1 aJ/s = 1e-11 erg/s.
