<p>What would be the SAT equivalence to a 21 ACT Math score? I would estimate between a 510-520. Does anybody have a better idea of what it would be?</p>
<p>Sounds about right. Converting an ACT score to an SAT score can only give you a rough estimate anyway.</p>
<p>Is there an ACT subscore conversion chart available?</p>
<p>Both ACT and Collegeboard have charts on their websites, which you can find with a quick Google.</p>
<p>This is the ACT one: [ACT-SAT</a> Concordance](<a href=“http://www.act.org/aap/concordance/]ACT-SAT”>The ACT Test for Students | ACT)</p>
<p>I used percentile charts from both college board and ACT student just now and it shows almost a 540 for a 21 math. That doesn’t seem right.</p>
<p>^If 500 SAT and 18 ACT is average, as they were designed, that would be right, but I think the SAT’s average is actually closer to 500 than the ACT’s is to 18. Still, ten or twenty points isn’t a big deal.</p>
<p>I’m confused what you mean by “average.”
540 just seems a bit high compared to 21 on the ACT, in my opinion. But I could be wrong and probably am. :)</p>
<p>who cares its a 540…</p>
