Hey /p/, probably an autist-level question about a lens.

I have a Rebel T6i that I'm looking to get a new lens for, a 24-mm f/2.8.

Looking at the description on Amazon, there's a line that I'm not sure about.

>Wide-angle lens for Canon APS-C cameras (equivalent to 38mm on a full-frame camera)

Any way I can tell what the actual focal length would be? I'm still obviously learning and I don't wanna fuck it up before I buy it.
