Re: Scope and format of world data sheets in SF
I for one use metric for “sciencey” and mechanical stuff (car repair) and regular US units for life in general. Grew up in Texas but have been tinkering on VWs and Hondas since high school and work on Japanese-made semiconductor manufacturing equipment. Use a 12mm wrench and add a quart of oil, 2.3 liter engine with 220 horsepower, water in my machines flows at 40 L/min with the bath at 20.1C, but it’s 52F outside... it’s all a mix of US and metric now for me, and same for quite a few others.
Planetary data is definitely Science enough to go full in. kPa and m/sec and km all work for what you’re doing, I think. It’s easy enough to convert if really necessary, and metric makes it more future/space SF in tone and feel.
