Why are the Eligibility indexes for ACT and SAT different?

Why are the eligibility indexes used for ACT and SAT different? Using the SAT has a significantly higher number compared to the ACT. For example, when having both of the highest scores (1600 and 36) and including a GPA of 4, the SAT is 4800 compared to ACT's 1160[The formula for each is ((High School GPA × 800) + SAT (Evidence-Based Reading and Writing, and Math)= Eligibility Index) and ((High School GPA × 200) + (10 × ACT Composite Score)= Eligibility Index)]. Is it because the SAT is preferred more? And if not, then how does SDSU compare Eligiblity Indexes using SAT's to ACT's?

SAT is used more in California but there are two different scales used by Cal State campuses. The one that shows up on campus websites is usually the SAT-based eligibility index. I'd suggest "converting" your ACT score to an SAT Score (which is difficult) but there are helpful charts online such as this: https://blog.prepscholar.com/act-to-sat-conversion.

But basically, more students submit SAT scores in general.
