Dimensional Analysis Explained!

[@willismajor1113]

Super helpful. I’m taking an online college chemistry class. Needed to watch how it’s done rather than just in the text! Thanks very much!

[@partyhah6622]

Oh. This is usually taught in college? My teacher is making us do this in 8th grade. Kinda sucks for me though.

[@gingerale1591]

@@partyhah6622 It's not that it's taught in college. Most college freshmen (like me) just forget it by the time college rolls around. A lot of us haven't had to do this stuff for a few years. My advice to you is to keep this stuff fresh in your mind before you start college so that you don't have to cram-review everything. Best of luck with 8th grade.

Insanely helpful taking algebra 1 and I’m a freshman this cleared up any doubts or inconsistencies I possessed, thanks!!

Amazing video! I'm a 30 year old software developer and I just understood unit conversion for the first time XD. Thank you so much!

[@RobinReaction]

wow that's awesome! hope you have to convert some units soon so you can get practice!

[@parkersorensen7602]

Why did you even need to learn it?

[@Infernovogel]

@@parkersorensen7602 because I need to convert units a lot. Are you looking for a more specific information?

[@sarahtaylor2586]

I have a test in chemistry on dimensional analysis Monday, and I have to say this video helped me tons!! Thank you! I didn’t understand this really at all before I watched this but I would totally recommend this video if you need help.

[@RobinReaction]

aww yay! I'm so glad it helped you!

[@chezarctica7386]

Great video!! You explain everything so crystal clear. Wish every teacher was as clear as you are.

[@RobinReaction]

aww ty so much! good luck in your course!

[@alanamendez339]

Thank you for this video. I was stuck on a complex problem and getting frustrated but this video (especially the last question) helped me so much. Now I'm solving these with ease!

[@thecaptainasian]

nice my teacher is showing this video for us in elementary accelerated math and it helped greatly

[@Super-vk4xh]

YOU NEED MORE SUBS IM ON A ROBIN BIENGE RIGHT NOW

[@RobinReaction]

hahaha lol thank you!!!!

[@klsoto3481]

This video is a gem! Thank you for taking the time to share this with us. I am confused about how the calculations after multiplying the numerators gave us a 10^16. How did the exponents go from 10^9 to 10^16, and then in the final answer it is 10^10. Thank you!!

[@dgrassey]

That was so WELL explained! Well. done!

[@daveyoung3207]

that told me a lot about unit conversions! THANK YOU FOR HELP!

[@sophiaduncan347]

This is the very first time I have ever understood dimensional analysis. Thank you

[@dekumidoriya7583]

Perfect! used it for my Physical Science class

[@twentysecondcenturywoman]

Thank you so much for this video & the even slower one. I can't get this subject down for some reason. Wonderful explanation.

[@susanw3532]

In your last problem, the 78 mph to miles per second if I remember correctly, you had scientific notation for 10 >16, I did not see where you got that. This video was super helpful, I just got lost at that point.

[@qzorn4440]

sweet video. 😎 thanks. A very relaxing voice to learn by. 🥰

[@jakezhenry007]

Thanks that was a good refresher 🙏🏽

[@taylorgulbrandson7962]

Thank you so much! My teacher confused my so much and now I understand.

[@sophiaduncan347]

My professor had me so confused, I dropped the course.

[@nora7535]

thank you this has helped me so much !!

[@RobinReaction]

yay I'm glad!

[@lyndseymeagenwalker3057]

The division for the last nm conversion did not give me the same result you found. What did you do to find 3.5x10^10th? Otherwise amazing explanation. Thank you!

[@magdajohnson3848]

The best tutorial ever. Thank you!

[@jeremiahnathan3623]

I have learned a lot from you channel Thanks

[@RobinReaction]

you're so welcome!

[@gracemostek1976]

best explanation out there!!

[@RobinReaction]

ty!!

[@이민지-x3u]

Omg, than you!! I literally watched every single video of yours!! Now I get it!! yay

[@lcdp9459]

Thank you!! ❤

[@shyletchikara3936]

very much appreciated

[@daisyshaw635]

THANK YOU SO MUCH ROBIN

[@youarestellar1131]

tysm! This really helped 😊

[@nacerlifa]

Good video. Keep it up

[@MsArocha241]

How did you get 10^16 nm? I am so confused by that

[@MsArocha241]

And then followed by 10^10 nm/s *crying lol

[@wyattmcinerney4702]

Thank you!

[@RobinReaction]

you're welcome!

[@tatiz111]

Can someone explain how she got 1.255x10^16nm plz.

[@cynthiagonzalez8702]

I love your channel

[@RobinReaction]

thanks! glad you enjoy it!

[@Dave45784]

Can you link me to your easy version please

[@bme7995]

My given number is 1.50 x 10^6, is there power of 10 in chemistry picket fence formula? I’m so confused and my teachers aren’t even explaining it.

[@bahablastisbadbahamama844]

thank you for explaining this i have a quiz tomorrow

[@quesiachagas5446]

It would be more helpful if you had explained how did you get 10^16. I got everything but this part.

[@ChemEICast]

Using Scientific notation method. I explained it if you're interested

[@mckaylamurphy126]

THANK YOU

[@Natalia_marin22]

Thank you!!!!!!

[@arniarora8066]

tysm have a test tmw

[@RobinReaction]

good luck!!!!

[@94mac]

At 11:04 did you mean 10^-9 not 10^9? Nano is -9

[@ChemEICast]

10^-9 should be on the bottom, so it will be 10^9 above

[@chemistryhoff2353]

Check out another video on Dimensional Analysis: kzbin.info/www/bejne/r32xqI1sn5h_lZI

[@kanikapaul523]

Nice

[@DamnHotWasabi]

God damn your my new hero.

[@georgeonyeka5224]

What value of x, y, and z, will the equation P^x v^y T^z = constant, become Boyles law? (P ∝1/V at constant T)

[@alexanderchang8376]

Thank you so much, I am a god at da now lets go

[@theywontfindme1471]

got a final tomorrow and thinkin of throwing myself off a building because if I fail this ill have to take summer school

[@chezarctica7386]

How did you do?

[@lachlandudley7478]

Awesome stuff! Clear explanation. However, if I could offer one comment for improvement; you sound bored! You obviously enjoy math, so why not put a bit of energy into it! :)

[@RobinReaction]

lachlan dudley haha I’ll keep your note in mind. I’m usually concentrating very hard while making the videos so I think that’s why my voice could come off as unemotional.

[@fernandobezerrademenezes1622]

Dear Robin, first congratulations for your channel. I would only suggest an easier way for converting 78 mph into nm/s. I would start with 1 mile = 1609 m. Then we have 78 miles/h = (78 x 1609) m/h = [(78 x 1609)/3600 ] m/s = [(78 x 1609)/3600] x 10^9 nm/s = 35 x 10^9 nm/s = 3.5 x 10^10 nm/s (with appropriate rounding).

[@nirajbhusal9961]

Nepali to english medium

[@davidmutchock9261]

do the math???????????? but where do you get the 3.5x10,10 they always come to the end, the part I dont get and say "and do the answer" ta dah

[@legallyblind3631]

Omfg you are the best thing ever. Can you give me a thumbs up down there??

[@RobinReaction]

lol here you go!

[@izoki1213]

eighth grade math sucks 😩

[@Jay-uo5of]

was helpful until you pulled out those grid things to do multiplication and division. it needless complicated it to the point i had to restart the video and mute you, and work on it by myself.

[@hwana6773]

POOOOOOOOOOOOOGGGGGGGGGGGGGGGGGGGG

[@Misslayer99]

Great explanation really helpful! I got the last one right 😄

[@robertturner1308]

Thank you!
