  The hubble constant being simplified to Hertz and then it's inverse ending up as an approximation of the age of the universe absolutely blew my mind.

  I love how it feels like the background music is equally upset about all of this as the narrator

  Fuel consumption of an excavator is measured in liters per cubic meter, which is dimensionless.

  The little detail of the piano seemingly following a random walk on a whole tone scale while random walks are being discussed is amazing

  Calculating the Hubble constant as a music note (all notes are just frequencies) gets us an E 67 octaves below middle C.

  In high school, I had an extra credit questions for the precise speed of light in a vacuum (299,792,458 m/s). I wrote 1 light year / yr. Got my points.

  In my PChem class the instructor made the error of saying he didn&apos;t care what energy units we used on a test. &nbsp;He really meant it didn&apos;t matter to him whether we used joules or calories, but I took him at his word and turned in my test with all the energies expressed in liter-atmospheres.

  In middle school I wondered why rain was measured in mm instead of something logical like litres/m^2 until it clicked and I realized they are the basically the same unit.

  My favorite is s^-1 / s^-1, where the units don&apos;t actually cancel.<br><br>(One is a frequency, the other is an <i>angular</i> frequency, and so is off by a factor of 2pi.)<br><br>In general, anything involving radians is &apos;fun&apos;, because people declare it to be unitless and then omit the unit, and then get really confused.

  <a href="https://www.youtube.com/watch?v=kkfIXUjkYqE&amp;t=100">1:40</a> -- &nbsp;WOW, in an instant, this took the area measurement of fuel efficiency from &quot;utterly boggling and incomprehensible&quot; to &quot;the most obvious and intuitive way to express fuel efficiency&quot;
