Answer
| Absolute Humidity | Relative Humidity |
|---|---|
| It is the measure of the actual amount of water vapour in the air, regardless of temperature. | It measures water vapour in air but relative to maximum vapour that the air can hold at that temperature. |
| It is expressed as grams of moisture per cubic meter of air. | It is expressed as the ratio between the absolute humidity of a given mass of air and the maximum amount of water vapour that it can hold at the same temperature. |
| The higher the amount of water vapour, the higher is the absolute humidity. | Warm air possesses more water vapour than cold air, so with the same amount of absolute humidity, air will have a different relative humidity depending on temperature. |
| In weather calculations, absolute humidity is generally not taken into account. | It is the essential characteristic of weather forecasts, which indicates the likelihood of precipitation, dew or fog. |
