What Is This Tool?
This converter transforms power values measured in kilojoule per second (kJ/s), a common SI unit for energy transfer rates, into erg per second (erg/s), a CGS unit often used in astrophysics and older scientific literature. It helps express power in units preferred in specific scientific fields.

Examples
-
2 kJ/s equals 2 × 10000000000 erg/s = 20000000000 erg/s
-
0.5 kJ/s equals 0.5 × 10000000000 erg/s = 5000000000 erg/s
Common Use Cases
-
Rating electrical or mechanical power output or consumption in appliances and motors
-
Quantifying thermal energy transfer rates in heating and cooling systems
-
Specifying turbine or engine power in industrial and energy generation setups
-
Expressing luminosities and radiative power of astronomical objects in astrophysics
-
Reporting power values in scientific research using CGS units
Tips & Best Practices
-
Use this conversion when working with scientific literature that employs CGS units
-
Verify unit context to ensure erg/s is appropriate for your application
-
Remember that erg/s values will be numerically large due to unit size differences
-
Prefer SI units like kilowatt or watt for everyday engineering calculations
Limitations
-
Erg per second is much smaller than kilojoule per second, resulting in large numeric values
-
CGS units like erg/s are less common in modern engineering fields compared to SI units
-
Not practical for routine engineering usage due to scale differences
Frequently Asked Questions
-
What does kilojoule per second measure?
-
Kilojoule per second measures power as the rate of energy transfer, equal to 1,000 joules per second and equivalent to one kilowatt.
-
When should I use erg per second units?
-
Erg per second is useful in astrophysics and theoretical calculations where the CGS system is standard, especially for luminous and radiative power measurements.
-
Why are erg per second values so large when converted from kJ/s?
-
Because erg is a very small unit of energy compared to kilojoule, converting results in large numeric values, making it less practical for everyday use.
Key Terminology
-
Kilojoule/second [kJ/s]
-
A power unit measuring the rate of energy transfer equal to 1,000 joules per second, equivalent to one kilowatt.
-
Erg/second [erg/s]
-
A CGS unit of power equal to one erg of energy transferred per second; it corresponds to 1×10⁻⁷ watt in SI units.
-
Power
-
The rate at which energy is transferred or converted, typically measured in watts in the SI system.
