Relative humidity (RH) is calculated using which formula?

Relative humidity is how much water vapor is in the air compared with how much it could hold at that temperature. It’s the ratio of the actual amount of water vapor (absolute humidity) to the maximum amount possible (humidity capacity or saturation), multiplied by 100 to express it as a percent. So the valid form is percent RH = (absolute humidity) ÷ (humidity capacity) × 100. If the actual amount equals the capacity, RH is 100%; if there’s less vapor, RH is lower. The version without parentheses is functionally the same in standard arithmetic, but the version with parentheses clearly shows the intended grouping.
