What exactly is a Julian year in this context?

A Julian year is defined as exactly 365.25 days of 86,400 SI seconds each, totaling 31,557,600 seconds, and is used as a standard duration in astronomy.

Why convert Julian years to seconds?

This conversion is essential for expressing long-term astronomical time spans in precise SI time intervals used in scientific experiments and synchronization technologies.

Can this converter be used for civil timekeeping conversions?

No, because the Julian year is fixed and does not account for the varying lengths of solar or calendar years used in civil timekeeping.
