Crude Oil Density conversion to 15 C from observed temperature as per ASTM 53A  and volume Correction as per Petroleum tables ASTM 54A using an App developed. The App developed converts a) Density at 15 Deg C from observed density and temperature and b) calculates the bulk volume from natural to volume at 15 deg C, US barrels at 60 deg F and weight in MT. Large volume of crude moves from production to user refineries globally. Oil Industry uses ASTM tables published by API/IP/ASTM  to account Oil quantity on board of the tankers for calculating quantity.  Following publication is in IS system where mass is in Kg, volume is in Kg/Cu.M and temperature is in Centigrade and followed most of Europe, Asia, Africa & Commonwealth countries with standard temperature as 15 deg C. It may be noted that the above tables ASTM 53 A and 54 A are for Crude oil and not for refined petroleum products for which there are different ASTM tables for Corrections. See different...

An App is developed for Jet A-1 Density conversion to 15 C from observed temperature as per ASTM 53B.  Large volume of Jet A-1 after refining moves from production to airports globally. Oil Industry uses ASTM tables published by API/IP/ASTM  to account Oil quantity for calculating quantity. For insuring quality of these sensitive products density is the only convenient and easy factor to measure in the field outside the laboratories.  The density is measured at the ambient temperature and then converted to standard temperature say 15 or 20 deg C. The converted density at 15 deg C is compared with the parent or source density at 15 Deg C and the difference in this limited to a certain limit gives assurance of the Quality of the product.  JIG gives this variation in density at 15 Deg C as 3.0 Kg/Cu.M. Following publication is in metric system where mass is in Kg, volume is in Kg/Cu.M and temperature is in Centigrade and followed most of Europe, Asia, Afr...
