We investigate what relative humidity is, why it matters, and what it means for your home.

On a calm, clear night, the ground cools very efficiently by radiating heat back into the atmosphere. This lowers the ...

Mike Moss: Relative humidity is not related to temperature and dew point in quite that direct a manner, although they certainly are interdependent quantities. There are some online calculators ...

We tend to measure humidity in terms of Relative Humidity (RH). This looks at how much water vapour there is in the air compared to how much there could be at that temperature.

What is the difference between dew points and relative humidity? — Nancy, Tulsa In short, the dew point is the exact measurement of how much moisture is in the air.

Most people understand relative humidity, but the dew point is a much better measure of how humid it really feels.

So, what is the difference, if there really is one? To find out, let’s dive into what dewpoint is and what relative humidity is. Dewpoint is a more direct measure of moisture in the air.

How can you measure the humidity level in your home? If you’ve been searching for the answer to this question, you may have come across the two terms: relative humidity and absolute humidity.

However, the relative humidity in this case would only be 52%, giving no indication of the true feel of the air. Dew point and frost or snow The dew point is also a useful measure in other seasons.

Some weather stations measure relative humidity and other key metrics from outside your home.

Comparison As noted earlier, when looking at relative humidity, Alaska is the most humid state. This is a function of the low temperatures. A cold airmass simply cannot hold a lot of moisture.

There are several ways to measure humidity. The most commonly used is relative humidity, which compares the amount of water vapor in the air to the total amount that air can hold. This measure ...
