The Eiffel tower is Paris’s most recognizable landmark, and is of key importance to @mlscience. So far, the Eiffel tower has been used in three separate calculations as a reference (one of which hasn’t been posted yet!). Really, we wouldn’t know what to do without it.

Melting the entire puddle iron structure of the Eiffel Tower (which means this excludes the stone foundations, paint, etc.) and compessing it into a big ball would give you this.

The sphere would have a volume of ~935,000 Liters and would weigh ~7,300,000 Kilograms.

Some more calculations regarding the Chemistry and Physics of the composition of the Eiffel Tower can be found here: http://www.thechalkface.net/resources/melting_the_eiffel_tower.pdf

It’s still pretty big.

LES HAUTEURS DES COLLÉGIENS V1.0

(Graphic made by Admin AT. Click here to view the full image in higher quality.)

(Adrien Agreste was used as a reference. To see how we retrieved Adrien’s height, click here and here.)

Using the pixel-proportion method, we now have a realistic and somewhat accurate list of the heights of the “collégiens”, or Marinette, Adrien and their classmates, minus Alix, Kim, and Max. This took a long time to do for various reasons, including the countless attempts to draw proper perspective lines on the reference image and the numerous calculations involving counting pixels, plugging the numbers on a calculator, and making that graphic above.

While we do have some pretty specific numbers up there, those shouldn’t be taken as 100% accurate results, due to some rounding off and other stuff that may have happened during the multiple stages of this project.

We might produce a more accurate version if we get more decent screenshots.

HOW TALL IS CHAT NOIR?

~PART 2~

Yes, this post looks familiar. No, this isn’t the same post. Here we are again trying to calculate Adrien/Chat Noir’s height even though we clearly already did in this previous post.

A LOT OF YOU said some things along the lines of ”Chat Noir is so tall wtf” and “How tall are the adults?” (~~which we will someday totally calculate btw~~), and Admin AT agreed that yes, Adrien does look a little bit… too tall for a french ~15 year old.

So we did it again. This time with fencing swords.

TL;DR We pulled out four possible heights from these calculations; ~156.5cm (5′2″), ~166.6cm (5′6″), ~171.7cm (5′8″) and ~181.7cm (less than half an inch shy of 6′0″), based on four different sizes of modern regulation fencing foils and épées.

“@mylittlehony said:

Just a quick correction to your height calculations for Chat Noir - 180cm may be equivalent to 5.9 feet, but that’s according to a decimal system. There are 12 inches to one foot, so 180cm is actually closer to 5′11″. Chat Noir is just shy of six foot, in that case.”

(The post concerned.)

Whoops. 8D

Thanks for pointing it out! I’ve changed the feet values in the post to 5′11″ and 5′5″. Hopefully everyone notices. (Also, Adrien is huge. What)

On a sidenote: I’m never trusting those instant Google conversions ever again.

~~Y’know what? I’m gonna calculate Adrien’s height again using his Mercedes.~~

HOW TALL IS CHAT NOIR?

As a science and mathematics blog, @mlscience needs a lot of data to calculate stuff. One such piece of data would be dimensions; length, height, width, etc. These dimensions are crucial in order to calculate how fast things go, how heavy things are, and how much volume everything has.

We needed to find someone’s height, so we set our eyes on one of the easiest candidates: Chat Noir. We also needed something that we can compare him to in real life, and that thing turned out to be Leonardo da Vinci’s masterpiece, the Mona Lisa.

TL;DR: Chat Noir is about ~180cm (5′11″) tall, assuming that Copycat and Chat Noir are exactly identical in height and that the Mona Lisa portrayed in the show has the same dimensions as the real life Mona Lisa.

(Special thanks to @madelinelime for providing us with HD screenshots, and to @mylittlehony for pointing out an error in the cm to feet conversions!)
