It seems to be converted in Pascal here zed_wrapper_nodelet.cpp:2964

The chart is my downstairs data. It looks like the unit should be Pascal*100, but the press change of ZED2i is very bad. The chart on the right side is the barometer of my phone

Hi @arenas7307979 the ROS units for the pressure is Pa, according to the topic definition. I agree that there is a bug in units conversion, we're fixing it.

Regarding the measurement. The sensor is inside a closed case, so you must take it into consideration.
