How can we help?

Concerning Algebra 1 : Rate Conversions. Also known as Dimensional Analysis.

I think the hints, and how they are written, need to be revised and improved. Maybe an extra video. But definitely the hints could be more detailed / explanatory.

Background and legitimacy of my suggestion: I've spent 4.5 hours on this relatively minor area. But it's a very important skill to master in math. Being able to convert weird dimensions such as km/m^3 to m/m^2 etcetera. I've 1.5million points and this is only the second time I've had to really, really go somewhere else to get my head around this part.

That all said, I'm looking forward to continuing my journey with Khan after this mental block, it seems. First time it's happened like this to me so far on Khan.

Hi Oscar,

Thanks for the feedback! I'll forward this to the relevant content team so they can review and potentially revise our content on unit conversions!

In the meantime, if you have any specific questions about unit conversion, I suggest you post your questions on a related video or article. This will allow other members of our community to help explain the topic to you and is the fastest way to get your questions seen and answered.

I hope this helps! Please let me know if you have any additional questions!

Hi Evan,

Concerning the subject matter found at Algebra 1 > Working With Units

FYI this Youtube video did explain Unit Conversion adequality: (11) Unit Conversion the Easy Way (Dimensional Analysis) - YouTube

Thanks to this video I was able to complete Algebra 1 > Working With Units after a bit more practice.

I think it's very important Khan improves Algebra 1 > Working With Units because:

Over-confident math students might start off at Algebra 1, instead of, say, Year 5 or 6 for example (I personally started from Year 1 a year ago). And if a portion of the over-confident students are met early on in Algebra 1 with video's that, in my opinion, do not explain a process of doing unit conversions, then Khan might have a higher than normal drop-off-rate at this particular point in the course (Algebra 1 > Working With Units). If so, that'd be shame because they may be put off too early yet Khan actually does such an incredible job in all his other videos, except all the videos in Algebra 1 > Working With Units (except for the very last video where Khan started to explain the process better).
