In relation to Class A, multiply the number in front of the letter by 1.25 to indicate how much water the extinguisher contains. For example a Rating of 2-A shows the unit contains 2.5 gallons of water.
For a Class B Rating, the number shows how many square feet the extinguisher can suppress.
Classes C, D, and K do not have a numerical rating.
