Calculate relative humidity RH using the formula, RH = 100 × {exp [17.625 × D p / (243.04 + D p )]/exp [17.625 × T/ (243.04 + T)]}. Relative humidity expressed as a percent, is a measure of the amount of water vapor that air is holding compared the amount it can hold at a specific temperature. Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a higher relative humidity.

3.2 Air temperature measurement. Air temperature is a key measurement alongside relative humidity. This is because the “relative” aspect is effectively “relative to temperature” (how saturated the gas is at its current temperature). For a given air sample, a rise in temperature means a fall in relative humidity. A psychrometer is a hygrometer made up of two thermometers that are identical.
