How the 60-evdev.hwdb works
libinput made a design decision early on to use physical reference points wherever possible. So your virtual buttons are X mm high/across, the pointer movement is calculated in mm, etc. Unfortunately this exposed us to a large range of devices that don't bother to provide that information or just give us the wrong information to begin with. Patching the kernel for every device is not feasible so in 2015 the 60-evdev.hwdb was born and it has seen steady updates since. Plenty a libinput bug was fixed by just correcting the device's axis ranges or resolution. To take the magic out of the 60-evdev.hwdb, here's a blog post for your perusal, appreciation or, failing that, shaking a fist at. Note that the below is caller-agnostic, it doesn't matter what userspace stack you use to process your input events.
