Astronomical Units and Lightyears do just fine. Maybe the rest of the world will try them someday though, I guess terameters and petameters are useful if you need to know how many microns it is to Jupiter.
- Someone 3y agoA light year is 9.46×10^¹⁵m. I think rounding that to 10¹⁶m (ten petameter) is fine for armchair astronomers. ‘Real’ astronomers like to use the parsec, too (about 4.2 light years, IIRC)
- AA-BA-94-2A-56 3y agoAU is also very easy for me to understand as a lay person.
