Talk:API gravity

What is the history of API Gravity? How was the arbitrary scale developed?

The API standards commitee developed it around 1910(?) I wasn't able to find much historical discussion of the API gravity scale on the net. The arbitrary scale was just a formula based on specific gravity so that the values would be between 10 and 70... why 10 and 70? ... I have no clue. Best bet would be to contact the API standards committee directly or talk to someone in the petrochemical industry for more info. -- jonathan888 29Jun05

The degrees Baumé information given by Gene Nygaard allowed me to track down the history of API gravity and I added a few more pages about degrees Baumé and Antoine Baumé. -- jonathan888 26Sep05

Editing Notes

Under the "Direct Measurement of API gravity (Hydrometer method)" I wasn't sure how the first word "Thvus" should be read and/or editted. Overall very insightful article, thanks for starting it.Snapdogs1966 (talk) 13:30, 19 April 2012 (UTC)

Comment / Proposal for Update

The API has deprecated the term "specific gravity". See, for example, Manual of Petroleum Measurement Standards Chapter 11.1 (2004) section A.10:

<<Quote>>

Following the convention specified in 15.2.4.8 of API Publication 2564, Second Edition, and with the concurrence of the Institute of Petroleum, the term “specific gravity” was discontinued. It was replaced with the term “relative density.”

<<Unquote>>

As this article relates to the API gravity, it would make sense to use API terminology. Should SG therefore be removed, and replaced by RD? 81.187.236.11 (talk) 12:55, 28 November 2013 (UTC) Mike Seabrook
