SAT to ACT conversion
840 SAT to ACT
ACT composite equivalent
14
Official College Board / ACT concordance
A 840 SAT total converts to about a 14 ACT composite.
On the 2018 concordance jointly published by the College Board and ACT, every SAT total from 830 to 870 maps to an ACT composite of 14. Each ACT point covers a wider band of SAT points, which is why the conversion is a range rather than a one-to-one match. Colleges use this same table to compare applicants who took different tests.

What to do with this number
A score only means something next to a college list.
National percentiles and concordance tables tell you where a score sits across the country. They don't tell you whether it's competitive at the specific schools your student is considering, or what to work on between now and application season. HIYP tracks a student's scores, grades, courses, and activities year by year and turns them into the next concrete step.
