Apologies if I dont understand how this works properly, but I would like to comment on the article about Mars atmosphere. I am very interested in understanding how greenhouse theory might also apply to Mars. and other planets. To do this I wanted to understand how much CO2 was in the Mars atmosphere...both the concentration and the pressure. This article states that the pressure of Mars atmosphere is 610 Pa or 0.088 psi. This assumes the normal conversion factor which applies on Earth... but cannot be true for Mars. The Pascal unit for pressure is is based on a N/ m2  where the Newton has a gravity component F=ma  to convert pressure in Pa to a mass per unit area such as kg/m2 or psi you have to divide by the gravitational constant which is 9.8 on Earth but only 3.7 on Mars. Therefore the pressure on Mars might be 610 Pa OR .088 psi but it CANNOT be both of them. I would really like to be sure which it is. ? TFMANN (talk) 12:29, 22 January 2020 (UTC)
