To go the other way, from psi to bar: divide by three, take two of those thirds, and take a zero off the end of it.ġ800 psi ÷ 3 = 600 x2 = 1200 remove a zero 120 bar but who cares? You ever have one of those buddies with an AI computer who tells you their pressure to the single digit? Yeah. And gives us a super-easy 2:3 ratio.Īll you need to do to go from bar to psi: add 50% then tack a zero onto the end.ġ60 bar +80 (which is 50%) = 240 tack on a zero and you get 2400psi. Those are actual numbers that an SPG can read. So it stands to reason that if 1 = 15 then 20 = 300. Because **** it pressure gauges aren't that accurate anyway. A pattern I'm pretty annoyed no one ever told me about.ġ bar = 14.5 psiBut for math in our head let's call it 1 bar = 15 psi. ![]() If it was my strong suit I'm sure I would have noticed the pattern much, much quicker than the two 90 minute dives it took me today. Instead, every 20 minutes or so, I wound up doing math in my head. I could have just gone lazy about it and just trusted that my 5 minute switches were keeping the tanks even enough. But it's rare that I have to convert so frequently on the fly as I did today, constantly switching sidemount regs and making sure that my tanks were balanced. I've grown very comfortable switching between the two for gas planning purposes, so talks on the surface were a piece of cake. What's more, in our team we had some people who are used to metric and some used to imperial. Which is in a different format than the SPG on my right tank. Had to resort to the spare sidemount SPG on my left tank. Because I forgot my Teric (again) and, therefore, couldn't use my fancy transmitter. So today I wind up with a sidemount pressure gauge in bar and one in psi. Because I've simply accepted that it is so. ![]() You don't see me screaming about how gravity is corny and that we never got a sequel for Buckaroo Banzai, do you? No. Whether you like it or not is irrelevant. Americans, let's take it as a given that the whole rest of the world uses metric.
