Explaining ACT score

Ok, so my question is a weird one. I got a 31 on my ACT, and many classmates and relatives are confused by the ACT. Not sure why, but when I tell them my score, they kind of say “oh, ok” and seem to not know what to think. A 31 is a great score (not a brag, the truth), even if all of the overachievers say otherwise. I usually have to say that it’s the 97th percentile just so they understand, and THAT feels like bragging.

Would it be unethical/wrong to just say my SAT equivalent? Everybody seems to know the SAT scale, and it would be easier to say I got a 1390/1600 than a 31/36. I feel like it would clear up confusion and the puzzled looks I get when I say it.

EDIT: I took the new SAT and got a 1200, which is like a 25 ACT

@as1799 - if your classmates don’t know about ACT, good for you, because they are not your competitors. IMO - whether people around you understand ACT or SAT does not matter. You know college AOs understand it very well!

You can say I got a 31, which equates to a 1390 on the ACT.
