Barometric pressure is traditionally measured in inches of Mercury. The early barometers used a partially filled glass tube of mercury with the end in a bowl of mercury. When the atmospheric pressure was high, the air pressure would push the mercury up the tube, and vice versa in low pressure.
Today in the United States, inches of mercury is sometimes used, mostly by the general public and people who don't know better. Meteorologists like to use millibars, and this is used in other parts of the world. The SI unit is pascals (Pa), and hectopascals are used by meteorologists worldwide the most, and used interchangeably in the USA as well since they are numerically equivalent to millibars.
