An exawatt (EW) is an SI unit of power equal to 10^18 watts, commonly used for describing very large power levels in astrophysics or planetary science.

How many terajoule per second equal one exawatt?

One exawatt equals one million terajoule per second (1 EW = 1,000,000 TJ/s).

Why convert exawatts to terajoule per second?

Converting exawatts to terajoule per second makes extremely large power quantities easier to express for energy planning and engineering contexts.

Common Use Cases

Calculating power output in astrophysics, such as luminosities of massive stars.
Estimating energy flows intercepted by Earth in planetary science.
Modeling global or national power generation capacities in terawatt scale.
Assessing hypothetical fusion device outputs at exascale levels.
Comparing large-scale power generation and consumption scenarios.

Tips & Best Practices

Ensure correct value input to avoid scale errors given the huge unit magnitudes.
Use the tool for context-specific conversions rather than everyday measurements.
Cross-check conversions when using them for critical engineering or scientific tasks.
Understand that terajoule per second is a practical unit for many engineering applications.
Recognize the exawatt is mostly theoretical except in astrophysical contexts.

Limitations

Exawatt is rarely applied practically due to its extraordinarily large scale.
Terajoule per second, while more common, still represents extremely high power values not used in routine scenarios.
Small conversion inaccuracies can have significant implications at these scales.
The tool does not account for precision beyond the provided conversion rate.
Conversion is focused on power units only; it excludes energy or other physical quantities.
