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?

Barometric pressure is just another way to say atmospheric pressure, which is determined by the weight/density of the air above you/a location.

Hurricanes are/cause low pressure zones in the atmosphere, the lower the pressure drops, the more intense the storm.
