What is barometric pressure and what does it mean when it comes to hurricanes?

I keep seeing that Hurricane Milton has record pressure but I don’t understand it. What does pressure of 905 mb mean and why is it important for understanding the size and scale (and potential devastation) of a hurricane?

I think of it like temperature to give me kind of an estimate of severity. Just drop the first number. So in the 60-80s, thats probably fine. 20-30s? Yeah that’s real cold so that’s a bad hurricane. 0-10degrees? That’s too damn cold/that’s too bad a hurricane.
