The symbol for pascal is Pa. There are 133.3223684 pascals in a mmHg. What is millimeters of mercury (mmHg)? ppm = (milligrams of solute) / (liters of solution).
gennemsnitsværdien altid skal være under 100 ppm Danish. Gennemsnitsværdien ved undersøgelsens start var 99, 4 mmHg. (snabbt utsläpp).
A measurement in ppm-hours is known as a Ct value, i.e., concentration x time. 1029 ppm-hours is the dosage you'd get from 1029 ppm in one hour, the dosage you get from 2058 ppm in a half hour, the dosage you get from 514.5 ppm in 2 hours. If you had a concentration of 362 ppm, you would have to wait 1029/362 = 2.84 hours or 2 hours and 50 minutes.
Färskvattenräka (P. pugio): 220 ppm.
In this equation, the constant of proportionality is called the solubility coefficient of oxygen in blood (aO2). It is equal to 0.0031 mL / mmHg of oxygen / dL of blood.
1 mbar to mmHg = 0.75006 mmHg. 5 mbar to mmHg = 3.75031 mmHg. 10 mbar to mmHg = 7.50062 mmHg. 20 mbar to mmHg = 15.00123 mmHg. 30 mbar to mmHg = 22.50185 mmHg. 40 mbar to mmHg = 30.00246 mmHg. 50 mbar to mmHg = 37.50308 mmHg.
