Time to drop into Wikipedia and take a gander, I think. EDIT: I'll be damned, TIL that the Earth has an area of 510.06 10^6 km², but Mars' is only 144.37 10^6 km², only about 1⁄3 the size (28.3%). permalink fedilink source parent hideshow 4 child comments replies: [–] JackbyDev@programming.dev 10 points 1 year ago* (last edited 1 year ago) (2 children) The circumference is roughly 40,000 kilometers. The original definition for a meter was such that 10,000 kilometers was the distance from the equator to the poles (so a quarter of the circumference). They got the math slightly wrong and didn't want to people to think the process was wrong so they didn't correct it. I forget the actual circumference but that is close enough for very rough estimates. permalink fedilink source parent hideshow 2 child comments replies: [–] dragonfucker@lemmy.nz 5 points 1 year ago (1 child) the distance from the equator to the poles is a quarter of the circumference permalink fedilink source parent hideshow 1 child comment replies: [–] JackbyDev@programming.dev 2 points 1 year ago Yeah idk why I got circumference and diameter mixed up.
