- Patel's Density Conversion for Liquefied Petroleum Gas (LPG)  from observed temperature to 15 C without use of  ASTM Table.  (Density unit Kg/m3).   A separate post for the density unit Kg/L is given here.  An exact conversion in Android /iOS App is given at the end of this article. Following simple method help in easily converting LPG density to 15 deg C, without using ASTM Tables, and without help of calculators. It is very handy for field persons who are taking density for comparing parent density for Quality Control purpose.  LPG is transported in pipeline or marine tankers in cryogenic conditions and usually sample temperature is around 02 -15 deg C. Two different alternate simplified ways are prescribed here. User may find their own alternative. Option 1.     For LPG.  (Density range 5Xx  to 590  Sample Temperature range ----------. ) Simplified   Formula     ...

Secondly, as per request from one of the users, LPG density units used here is Kg/L.   ( 1000 Kg/L = 1 Kg/m3).  Two different alternate simplified ways are prescribed here. User may find their own alternative. Option 1.    For LPG.  (Density range ...

Petroleum Products API Gravity conversion to 60F from observed temperature as per ASTM 5B  and volume Correction VCF as per Petroleum tables ASTM 6B using an App developed. Scrolling Down The App developed converts a) API Gravity at 60 Deg F from observed API Gravity and temperature and b) calculates the bulk volume from natural to volume at 60 deg F, US barrels at 60 deg F, US Gallons at 60F for Petroleum Products. Large volume of petroleum products 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. It may be noted that this App is using tables ASTM 5B and 6B,  for Petroleum Products and not for Crude Oil for which there are different ASTM tables for Corrections. See different Apps suiting this. US, Canada, Persian Gulf, etc where  FPS system   with API Gravity, US Barrels, and Deg F is more prevalent Standa...

Crude Oil API Gravity conversion to 60F from observed temperature as per ASTM 5A  and volume Correction VCF as per Petroleum tables ASTM 6A using an App developed. The App developed converts a) API Gravity at 60 Deg F from observed API Gravity and temperature and b) calculates the bulk volume from natural to volume at 60 deg F, US barrels at 60 deg F for Crude oil cargoes. 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. It may be noted that this App is using tables ASTM 5A and 6A,  for Crude oil and not for refined petroleum products for which there are different ASTM tables for Corrections. See different Apps suiting this. US, Canada, Persian Gulf, etc where  FPS system   with API Gravity, US Barrels, and Deg F is more prevalent Standard temperature being 60 deg F. Certain countries use...

An App is developed for Aviation products like Aviation Gasoline, Jet A-1 etc Density conversion to 20 C from observed temperature as per ASTM 53B.  Density Conversion to 20 Deg C for Aviation Products as per ASTM 53B. Large volume of Aviation products  after refining moves from production to airports globally.  Oil Industry uses ASTM tables published by API/IP/ASTM  to account Oil quantity on board of the tankers 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. 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, Africa & Commonwealth countries with standard temperature as  15 deg C. Certain countries use  2...
