Dew Point vs Humidity - National Weather Service

The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form. If the air were to be cooled even more, water vapor would have to come out of the atmosphere in the liquid form, usually as fog or precipitation.Get price

Dew point - Wikipedia

People accustomed to temperate climates often begin to feel uncomfortable when the dew point gets above 15 °C (59 °F), while others might find dew points up to 18 °C (64 °F) comfortable. Most inhabitants of temperate areas will consider dew points above 21 °C (70 °F) oppressive and tropical-like, while inhabitants of hot and humid areas may not find this uncomfortable.Get price

Dew Point Calculator

The US Occupational Safety and Health Administration recommends that indoor air temperatures be maintained between 68-76°F with a relative humidity of 20-60%. Dew point is also considered in general aviation to calculate the probability of potential issues such as carburetor icing as well as fog. In some cases, devices known as dew point meters are used to measure dew point over a wide range of temperatures. These devices consist of a polished metal mirror that is cooled as air is passedGet price

Dew Point Temperature: An Overview - ThoughtCo

Jul 29, 2019 · The Dew Point vs. the Frost Point . The warmer the air, the more water vapor it can hold. The dew point on a warm and humid day can be fairly high, in the 70s F or in the 20s C. On a dry and cool day, the dew point can be quite low, approaching freezing. If the dew point is below freezing (32 F or 0 C), we instead use the term frost point.Get price
