The ideal companion for professionals in the oil industry, bunker and cargo surveyors!
This is the newly updated free app provided by MMC (Mooring Marine Consultancy) especially designed for marine cargo surveyors and deck officers on oiltankers to help with cargo calculations. 

If you would like the full version, which contains both 1980 and 2004 ASTM tables, as well as LPG/NGL calculations and much more, please take a look at "Oil Calculator Pro" by MooringMarineConsultancy instead! Please see the link here: http://bit.ly/1i9xQd5

Calculator for oil enhanced replaces the old Calculator for Oil app which can no longer be updated. The new app does NOT contain any ads or other 'noise', and it is TOTALLY FREE just like the old one.

NEWLY ADDED FEATURES:
On request the following features have been added:
- Table 53 (A, B, D) for converting observed density to density at 15 deg C.
- Background and text colors are now customisable, in the settings screen.

All tables exactly match ASTM 1980 table values
- Calculate using either table 6A/6B/6D or 54A/54B/54D
- Calculate Metric Tons in Air using Table 56 or using (density in vacuo - 11 points)
- Conversion of API and density using table 3 instead of formulas

NOW ALSO AVAILABE FOR THE iPHONE IN THE APPSTORE: http://bit.ly/YvpDpv

The app uses the ASTM tables (1980) and formulas to calculate weights and volumes based on entered density@15 or API, observed volume and temperature, and calculates the following:
- Volume correction factor (to number of decimals of your own choice)
- Metric tons (vacuum)
- Metric tons (air)
- GSV (M3 @15)
- BBLS (@60)
- Longtons
- Gallons

Furthermore, the app can convert API to density @15 and vice versa.
Precision for VCF, GSV, MTons, LTons and Bbls can be changed using a settings screen. Settings are saved in the app so that when you use the app next time it will calculate with your chosen settings.

The app can calculate for crude oil, black and white products and lubrication oils, and input can be changed between density in vacuum / API, M3 and Barrels, and degrees Celsius / Fahrenheit.

Now also with settings to switch between calculation using ASTM Table 6A / 6B /6D (especially for US) and ASTM Table 54A / 54B, and an option to calculate Metric Tons in air using either Table 56 or (dens in vacuo - 11 points).

If you like the app, please rate, and submit any request for changes/improvements using the comments section in Google Play.
