This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!
