Oilcalcs HD, the iPad version of Oilcalcs is now available for download in the Appstore here:
Oilcalcs HD for iPad
The iPad version of Oilcalcs is equipped with the same utilities and capabilities as Oilcalcs for iPhone.
Obviously the layout of the various utilities has been adapted to suit the iPad version, and one advantage of this version is that all utilities are visible in the main menu and the user can comfortably jump between the various tools as required.
Oilcalcs HD recognizes all rotations and automatically adjusts the layout for any changes in orientation:
Calculator in portrait mode
Calculator in landscape mode
Most of the tools fit into the screen without scrolling, both in landscape and portrait mode. Only the following tools need scrolling a bit (but only in landscape mode):
Oil conversions tool (ASTM tables):
Oil converter screen
In portrait mode the tool shows completely:
Oil conversion using table C
Gas conversions tool:
LPG/NGL Converter screen
The same goes for the gas conversion tool in portrait mode:

Just like Oilcalcs for iPhone, the user can export the data in the calculator screen into the Quantity Record Database and view/edit this data as needed, by pressing the ‘Calculate’ button. The app will then ask for an appropriate title for the entry, and after the entry has been stored, the user can look up the entry in the Quantity Record Editor:
After selecting entry in the database
LPG density calculator: the density calculator works the same as in the iPhone version, and has an error info label at the bottom of the screen that displays appropriate information regarding any missing or wrong entries:
Error in LPG density calculation (sum of constituents > 1)
Fuel blending tools: 2 blending tools are included, one that calculates the final density or API (depending on whether in settings Metric of Imperial has been selected) after loading a 2nd parcel into a tank with known density / API, temperature and observed volume. The final observed volume and temperature are also known:
Blending 2nd parcel into a tank
The other blending tool lets the user enter the details of two parcels, with their individual density /API, temperature and volume, and calculates both the final density and which parcel needs to be loaded first in order to obtain a homogeneous blend:
Blending two components and deciding the load sequence
Settings: the user can set the following items both in the settings screen and in the calculator screen:
– ASTM table version: use 1980 version or 2004/2007 version
– Whether to use Metric or Imperial units / algorithms
– Whether to use Table 56 or (density – 11 points) for calculating Metric tons in air
If you want to change the precision of individual items such as Longtons, Barrels etc, these can only be changed in the settings screen, and the VCF precision setting is automatically set when you select which ASTM table version to use (although this can be overridden manually):
Settings – Metric units / Tables 2007
Settings – imperial units / Tables 2007
