SAT to ACT Score Converter Formula

Worked Example

An SAT total of 1300:

1. Look up 1300 in the 2018 ACT/SAT concordance table
2. 1300–1320 on the SAT corresponds to 28 on the ACT

About the concordance

The tables come from scores of students who took both tests. They give equivalent scores, not predictions: a 1300 means you performed like students who scored 28 on the ACT. Colleges use the same tables to compare applicants.
