What is an exawatt (EW)?

An exawatt is a unit of power equal to 10^18 watts, used to describe extraordinarily large power magnitudes such as those in planetary or astrophysical contexts.

What does megajoule per second (MJ/s) represent?

Megajoule per second measures power as one million joules of energy transferred or converted every second, equivalent to one megawatt.

Why convert from exawatt to megajoule/second?

Converting allows expressing extremely large power values into units commonly used in engineering and industrial applications, making them easier to understand and compare.

Supports very large energy scale conversions used in astrophysics and industrial engineering.
Browser-based and user-friendly interface for quick calculations.
Displays results in standardized units for clarity.

Examples

Convert 0.5 EW to MJ/s results in 500,000,000,000 MJ/s.
Convert 2 EW to MJ/s equals 2,000,000,000,000 MJ/s.

Common Use Cases

Describing planetary-scale energy flows such as solar power reaching Earth.
Comparing high luminosities or peak power outputs in astrophysical phenomena.
Assessing hypothetical large-scale fusion device power levels.
Expressing electrical or mechanical output of power plants in MJ/s.
Specifying thermal power and heat transfer in industrial systems.

Tips & Best Practices

Use the tool primarily for extremely large power values relevant to astrophysics or energy research.
Understand that MJ/s is more suitable for industrial or engineering scales.
Verify units before converting to maintain clarity and precision in your results.

Limitations

Exawatt values represent enormously high power rarely encountered outside scientific or hypothetical scenarios.
Megajoule/second is more practical for typical terrestrial power systems and may not align perfectly with exawatt scale needs.
Conversion should be applied carefully to avoid misinterpretation of extremely large numbers.
