What does gigajoule per second [GJ/s] measure?

It measures power as the rate of energy transfer equivalent to one gigawatt, used to describe large continuous power levels in scientific and engineering fields.

When should I use exawatt [EW] units?

Exawatt units are used to describe extremely large power levels like planetary-scale energy flows or astrophysical phenomena.

Why might converting GJ/s to EW result in very small numbers?

Because the exawatt is 10^18 watts while a gigajoule per second is 10^9 watts, the conversion results in tiny decimal values due to the large magnitude difference.

Tips & Best Practices

Use this conversion mainly for order-of-magnitude comparisons involving very large power scales
Be aware that exawatt values will be extremely small decimals when converting from gigajoule/second
Apply conversions in contexts like astrophysics or global energy planning rather than typical engineering calculations

Limitations

Conversion is not suited for precise calculations at smaller power levels due to vast unit magnitude differences
Resulting exawatt numbers can be impractically small for everyday engineering use
Primarily useful for scaling and high-level assessments rather than detailed design work
