I tried to post this yesterday, but I don't think it went through. If a repeat, I apologize.

"The Martian" is a popular book available possibly only on Kindle, about an astronaut who is abandoned on Mars and tries to stay alive until a rescue mission can reach him. The author is no Hemingway, but the book is somewhat gripping. The metric angle is that there are pages and pages devoted to detailed discussions of distances, quantities of water and fuel, areas of solar panels and indoor crop growing, weights, sizes of pieces of equipment, energy requirements, and so forth--and it is ALL in SI. Only complaint is the term "kph" used.

It is staggering to think how complicated the book's discussion of these items would be in "customary". Supposedly all the math was carefully researched and is accurate.
