relative humidity
which formula can be measured to solve density
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.

The amount of water vapor in the air changes significantly with location and temperature. so a listing of percentage of gasses in the atmosphere would be different depending on how much water was in the air sampled. That would not be useful, because the other gases in the atmosphere do not change all that much. So it is more helpful to describe the making of the atmosphere as dry air (containing no moisture) and then adjust if needed for the humidity at any one place and time.
relative humidity
relative humidity
The percentage of saturation of the air at a given temperature.
Oxygen saturation is the extent to which the blood is carrying as much oxygen as it is capable of doing. It is measured as a percentage. Oxygen saturation is the percentage of oxygen in the blood stream. Doctors become concerned when that percentage drops below 90%. It simple terms, at 82%, your brain other other organs are not receving enough oxygen to properly function. Anyone's oxygen saturation level varies from one moment in time to another. If you had a full copy of your sleep study report you might see reference to peak saturation (the highest saturation seen during the study), average saturation, saturation nadir (the lowest saturation recorded during the study), among other terms.
atmosphere can be measured in barometers.
relative humidity
How close to 100 % saturation of moisture in the air that it actually is.
Hydrometer? Reative humidity, measured in per-cent. (Percentage of the concentration of water vapor which saturates the local atmosphere).
Sp02 stands for Saturation of Peripheral Oxygen. This is an indirect way to measure the level of oxygen i n the blood. The level of oxygen can be measured using a pulse oximeter.
Vehicle gradeability is measured in percentage.
Dose is a measured portion of a medicine.
