TechComm “F” – My Altitude Review

The first rule of technical communications is to never assume anything about your audience/reader. I downloaded the app the find out the sea level for my location. I opened the app and there is a number across the top with a dozen other numbers below. Am I supposed to somehow magically know that the number on top is the relative sea level? There is no indication what this number represents! Also, I switched from metric to imperial and the temperature remained in Celsius.
