What is an exawatt (EW)?

An exawatt is an SI unit of power equal to 10^18 watts, used to describe extremely large rates of energy transfer.

How does kilojoule per second relate to watts?

Kilojoule per second (kJ/s) is equivalent to a kilowatt (kW), meaning 1 kJ/s equals 1,000 watts.

Why convert from exawatt to kilojoule per second?

This conversion helps express very large power levels in units more commonly used in engineering and industrial applications.

What Is This Tool?

This unit converter transforms power measurements from exawatt (EW), which describes extremely large power levels, to kilojoule per second (kJ/s), a unit common in mechanical, electrical, and thermal power measurements.

How to Use This Tool?

Enter the power value in exawatts (EW) you want to convert.
Select the unit exawatt (EW) as the input unit and kilojoule/second (kJ/s) as the output unit.
Click the convert button to see the equivalent value in kilojoule per second.

Key Features

Converts power values between exawatt (EW) and kilojoule per second (kJ/s).
Ideal for bridging extremely large power scales with practical engineering units.
Browser-based and easy to use without requiring specialized software.

Examples

Convert 0.5 EW: The tool calculates 0.5 × 1,000,000,000,000,000 = 500,000,000,000,000 kJ/s.
Convert 2 EW: The result is 2 × 1,000,000,000,000,000 = 2,000,000,000,000,000 kJ/s.

Common Use Cases

Describing planetary-scale energy flows such as the solar power intercepted by Earth.
Applying power comparisons in astrophysics like luminosities of stars and supernovae.
Evaluating hypothetical exascale fusion devices and global energy scenarios.
Specifying power ratings in electrical, mechanical, and thermal engineering systems.
Quantifying energy transfer in HVAC and power generation industries.

Tips & Best Practices

Use the tool for theoretical or highly specialized contexts involving extremely large power values.
Double-check large numeric entries to avoid errors due to scale.
Understand that kilojoule/second results for exawatt inputs represent exceptionally large power levels not typical for everyday appliances.

Limitations

The conversion results produce very large values that are impractical for standard equipment power ratings.
Computational precision may be limited when handling extremely large numbers.
Mostly applicable for scientific, astrophysical, or large-scale energy modeling rather than common usage.
