About Oil Calculator Pro

1. For products, lube oils and crude there are two tools for calculating final density when blending two components: one tool that calculates the blend after loading the 2nd component, and another tool that lets the user choose the two components and advises which component to load first, based on density 15C or API 60F and actual temperature of the components.

2. The app can calculate for crude oil, black and white products, lubrication oils and special applications, and input can be changed between density in vacuum at 15 and 20 deg C/ API / relative density / observed density, and degrees Celsius / Fahrenheit by touching the applicable buttons.

3. Aside from the conversion screen with conversions between API, observed density, density 15, density 20 and relative density for petroleum products/Crude Oil and Lubrication Oil, there is also a screen with conversions used in LPG / NGL, as well as an LPG density calculator.

4. The user can also calculate weights of LPG / NGL, using either density @ 15C, relative density @60F, observed density or density @ 20C.

5. All other parameters are then calculated accordingly using the entered temperature, density (and pressure if 2004 version table is used).

6. The user has the choice to calculate using observed M3 / M3 at 15 / observed Barrels / Barrels 60 / Metric tons air/Metric tons vac / Ltons / Gallons.

7. The app has both ASTM 1980 and 2009 tables, and users can select which table to use for the calculator in the settings screen.

8. Contains an export utility so the user can copy calculator screen data into a database for future reference.

9. Oil Calculator Pro is the Pro version of Calculator for Oil enhanced, the indispensable companion for cargo and bunker surveyors, expeditors, chief officers on oil and gas tankers, and other professionals in the oil and gas industry.

10. IMPORTANT NOTE: for users who have problems with the keyboard (dot or comma not showing): some of the newer Android devices seem to have a bug in the soft keyboard, that results in the absence of dot / comma on the number keypad.

11. Users can also select whether they want to calculate using SI Metric or Imperial units.
