Plea to use for pressure not .
Reasons to use or avoid upper case:
1. Many of the pages about pressure use . Example: https://en.wikipedia.org/wiki/Ideal_gas_law There's a disclaimer that different fields use lower case and others use upper case . I think MOST audiences are like college students. Most of them will be using . In some grad school classes they use , but it cannot be stressed enough by me that those audiences are smaller.
2. Per https://en.wikipedia.org/wiki/Intensive_and_extensive_properties , there intensive things tend to be lower case. This would be why to stick with lower case for pressure.
3. Momentum has the same letter and is lower case. Momentum and pressure having the same variable is confusing.
2/3 reasons say raise case. Please, let's vote and pick the case most people are really using in real situations for the pressure. If I lose the vote so be it, then let's change all the uppercases to lower cases. To be using both cases is blatant tyranny. Jason Arthur Taylor Jasontaylor7 (talk) 20:28, 29 March 2021 (UTC)
