Convert FSW to PSIG
Multiply FSW by .445

Convert PSIG to FSW
Divide PSIG by .445

Convert FSW to ATA
Add 33 to the FSW then divide by 33 = ATA

Convert PSIG to ATA
Add 14.7 to the PSIG then divide by 14.7 = ATA

Convert ATA to FSW
Subtract 1 from the ATA then multiply by 33 = FSW

Convert ATA to PSIG
Subtract 1 from the ATA then multiply by 14.7= PSIG

Convert ATA to mmHg
Multiply ATA by 760 = mmHg

Convert mmHg to ATA
Divide the mmHg by 760 = ATA

Convert mmHg to %
Divide the mmHg by 7.6

Convert % to mmHg
Multiply the % by 7.6

Convert Celsius to Kelvin
Add 273

Convert Fahrenheit to Rankin
Add 460

To find the PP of Inspired Oxygen?
 Multiply the Total Pressure by % of gas(FIO2)
 PO2=PTotal x FIO2

Find the Arterial Partial Pressure of inspired oxygen.
 Subtract the partial pressure of water (PH2O =47) from the PTotal. Multiply that by the FIO2 then subtract the partial pressure of carbon dioxide in the alveoli (PCO2)
 PAO2=[(PTotalPH2O)xFIO2]PCO2

Dalton's Law
PTotal=ppN2 +ppO2 +PP of other gases.

Henry's Law formula
 P1/A1 = P2/A2
 A=amount ie: Liters, CC etc.

GayLussac's Law Formula
 P1/T1 = P2/T2
 Temp is absolute & Volume is constant IE: scuba tank.

Charles Law Formula
 V1/T1 = V2/T2
 Temp is in absolute & Pressure is constant because container is flexable IE:balloon at Sea Level

Boyle's Law Formula
P1 x V1 = P2 x V2

General or Combined Gas Law Formula
(P1xV1)/T1 = (P2xV2)/T2
