I’m aware that I can use codecogs to do latex images, but I didn’t feel like going to the hassle.
kWh is a common unit of energy, and “number of those units used in a single year” feels fairly natural to me. An answer in kW would be notationally simpler, but to understand what it was referring to, I’d need to convert back to “units of energy / time”, which is what kWh/year already is. And any answer expressed in kW is going to be an average power consumption over some period of time; kWh/year suggests that it’s probably averaged over a year.
I think we used both miles and km and converted when necessary. The number I had in my head was 1,800 miles, not the equivalent number of km; but we knew that the radius of the earth was 6,400 km, not the equivalent number of miles. I reported circumference-over-four in miles for consistency.
BTW, LessWrong does support LaTex, if you’re willing to work at it:
“Annual power usage” seems like a bit odd of a phrasing to me. Then you get kW h/year, when it could have been expressed as simply kW.
You had your discussion of length in terms of miles?
