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!

[Infernovogel]

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!

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

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.

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

YOU NEED MORE SUBS IM ON A ROBIN BIENGE RIGHT NOW

[alanamendez]

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!

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.

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

[dgrassey]

That was so WELL explained! Well. done!

[taylorgulbrandson]

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

[nora]

thank you this has helped me so much !!

[sophiaduncan]

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

[daveyoung]

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

[twentysecondcenturywoman]

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

[lyndseymeagenwalker]

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!

[jeremiahnathan]

I have learned a lot from you channel
Thanks

[dekumidoriya]

Perfect! used it for my Physical Science class

[fernandobezerrademenezes]

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).

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