Metre sea water[edit]

When you made this edit to Metre sea water, had you seen the discussion at Talk:Metre sea water? Multiple definitions abound, so I'm very tempted to revert your amendments as by giving undue emphasis to one source I don't believe they actually improve the article. --RexxS (talk) 11:26, 27 July 2017 (UTC)


@RexxS:: No, I had not seen that discussion. I agree with you that these units are not very rigorously defined. I think my edit actually emphasizes that fact, since I mention that the USNDM gives two slightly different conversions into psi! Feel free to modify the article after my edit, but don't revert! I fix'd several things.

By the way, another thing that influences the pressure change per foot or per metre (besides the density of the sea water) is the strength of gravity (or to be more accurate, gravity minus centrifugal force!). That changes considerably from one part of the world to another, similar to changes in density.

Indeed, Eric, the inconsistency in the USN Dive Manual is why it wasn't specifically attributed before, although Peter (I think) had used it as a reference. It's not a big deal, and as you say, the unit is a rather fuzzy quantity. I'm not going to revert your edits over such a small matter. Cheers --RexxS (talk) 16:09, 27 July 2017 (UTC)
