1.5 bars

147 kilopascals

that's what i've found too, guess the 10 kg/m3 is coming back then

It's really not that easy to find the information you're looking for. There's plenty of websites that talk about the atmospheric pressure on Titan, but that's not the same as it's density.

Titan's atmospheric pressure is about 1.5 atmospheres or 147kPa, but Titan itself is much smaller (and less dense) than earth, so the atmosphere must be denser to account for the loss of gravity.

I couldn't find a useful way to convert pressure to density in the proper units, but after some more digging, I found a reasonable source to confirm that Titan's atmospheric density is around 10-12 kg/m³ at "sea level".

aight, guess i'll use that for now
