What is the relationship between joule and erg?

One joule equals 10,000,000 ergs, representing the energy conversion from the SI unit to the CGS unit.

In what fields is converting joules to ergs commonly used?

Conversions are often used in astrophysics, classical mechanics, electromagnetism, thermodynamics, and historical scientific research involving CGS units.

Why might ergs be inconvenient for large energy values?

Because an erg is much smaller than a joule, converting large energies results in very large numerical values, which can be unwieldy.
