Fahrenheit to Celsius: History of the thermometer

How do thermometers work and how were they invented? Why does water freeze at 32 degrees on the Fahrenheit temperature scale but zero on the Celsius scale? And have you ever heard of the Réaumur temperature scale?

Watch this to find out everything you need to know about the history of thermometers and the temperature scales we use today.

I'm shocked at the low viewership/comments here. Excellent video, lads. Thank you for putting this together.

A thermo scope was created in A. Greece in the 3rd Century BC. The difference between a thermo scope and thermometer is the use of a scale. The credit of the first thermometer goes to Santorio Santorio around 1614. However, a consistent scale was needed since many thermometers were being created around the world. Daniel Fahrenheit and Anders Celsius create the system of measurements we use today. With Fahrenheit being an American standard and Celsius being a global standard in 1948. This video made me realize how many systems of measurements exist in the world of thermodynamics. I didn’t know there was a separate scale used for Italian and Swiss cheese production!

Thank you for this video! It helped me and my kiddos understand all this so much better!

That is some good drawing that went into this video.

6:21 Should be using Mrs. Fahrenheit's internal temperature. It is more accurate.

@7:53 what's the freezing point and boiling point for crickets:)

Interesting .... This is a good video 👍 it's very easy when you have with narrator and lyrics

So when did people start measuring weather and use temperature information in daily life? Origin, popularity and impact I really wonder. I had the same curiosity on clocks/time measuring, it was eye-opening.

Excellent video! I wish it was available in French too. I could have shown it to my students ;-)

Very ineresting explanation of something we take a simple advantage.Being heated from the sun, what suns action would effect the malfuntion of the thermometer.

To say that Fahrenheit was born in Gdansk is a massive anachronism. In a massive part of history, this place was Danzig, a German town in the German land of Prussia.
And so it was in his time, Fahrenheit obviously, as the name tells you, was a German!

Granddad had a Reaumur meter on his winter set of double glass windows.

How did that Greek guy make ice? Did he wait for winter? How did he know how the make 4° increments?

POV: ur a bukitsion student watching this in physics with miss raya

[Qwepo]

Is it just me or did someone else come here because their teacher asked them to watch this video

How did Galenus get ice for experiment in 180AD when artificially making water to ice was invented in around 1800 AD and Greece barely has snowfall.

As a child my body temperature was measured with a thermometer on my armpit

wow










































































what a waste of time..

The whole world should get rid of the stupid Celsius scale for measuring temperature and use Fahrenheit it's more precise the whole world should use metric in everything else measured just not temperature. For example kilometers is more precise than mph. just not the metric temperature scale
