    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!

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

      @@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.

    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!!

    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).
