I think you made a slight mistake, 1665513 m = 1665.5 km, not 166.55 :P
B-But... JackX, doesn't that depend on the air pressure, tempurature, and constituents of the air, which we have no idea of the measurements (save for the fact that Ambient Heat is a thing and it contains at least -some- oxygen and CO2 since things can burn and plants can grow)? :c
I still think using the pressure system ( ID:2165414 ) is better, as particles in TPT can go faster than the photons default speed, which would break the laws of physics in reality, and the speed of photons is changable anyway making it unreliable. The speed of sound in TPT is constant and cannot be changed, so that should be more reliable, and it works out the scale as roughly 1m/px
plutonium critical mass is 50kg in tpt 200 pix.
I remember seeing a save with the same name before...
lol, i dont know about that . +1
Light calculations usually gave scales that are extreme, considering most TPT saves.
Scale is again relative to saves.
