Do you want to know how much gas you are using? What is the maximum depth we can dive with Nitrox?
With the dive calculators simply input your data and it will mash them into the desired answer. Many settings and options are available. You can change easily from one system of measurement to another and even input from different ones in the same calculation.
A quick unit converter has also been included to help you to do the calculations.
MOD or Maximum Operating Depth
Enter the gas percentage, fraction or FO2 either in % or in decimal 0.XX. You can then choose the desired PO2.
Gas oxygen contentBest gas mix
Enter the depth and select the unit. Then select a PO2.
Enter the depthConverts units
To convert from one system of unit to another
Convert lengthEND or Equivalent Narcotic Depth
Enter the depth and select the units. Enter Helium content in fraction eg: 0.40 or in percentage eg: 40.
DepthEAD or Equivalent Air Depth EAD
SAC and RMV
To calculate the SAC or surface Air Consumption you will need to calculate the number of bar used.
Average depthLift bag required gas
Enter the weight of the object and its volume. Then pick the type of water.
Volume of the objectTank gas content
To calculate the total volume of gas in a tank according to the pressure and size.
Enter tank internal volumeCalculate required gas
Calculate the required gas volume for the bottom time of a dive. It does not integrate ascent consumption and is used only for informative purpose.
Bottom depthRelative altitude depth
Calculate the equivalent depth between sea level and altitude. Since there is no salty body of water at altitude, fresh water is used in calculations.
DepthThe values used in the conversions and calculations
It is important to remember that 10 meters are not exactly 1 bar. There is also a slight difference between the type of water where the dives take place. This can lead to disparities.
