20 bars to psi full#

Because a base 10 system that even works across different types of measurements is apparently far inferior to a system based on who knows (or cares) the antiquated **** what.

Seriously, I'm pretty bummed no one ever showed me this.Īnd now we can wait for the Americans to start screaming about how the whole rest of the world should change to THEIR system. Again, in my head (I didn't need my fingers for this one) I just sorted out that 1700 psi = 110 bar.Īctual conversion using software: 117 bar But, you know, I divided by way less than what I actually had, so I'm just gonna throw another 10 bar at it for good measure. I'm looking for bar, so I'l just add a zero to the 10 and have 100. Divide by three? Yeah, **** that, I'm gonna divide 15 by 3 and get 5. In my head (and on my fingers) I just now sorted that 170 bar = 2500psiĪctual conversion using conversion software: 2465 psiġ700 psi. We're looking for psi so we just add two zeros. So 25 (I know because I just now counted it using my fingers). We'll call it 8 because that's half of 16. And you'll be close enough for government work.ġ70 bar We'll work from 17.

Just work through the 2:3 ratio in whichever direction you need to go and then assume that there's two zeros if you're going into psi and only one if you're going into bar.Īnd, obviously, just squidge it by 100psi or 10 bar in whichever direction you need to go if you wind up working with a number that isn't divisible by 2 or 3. Or you can further streamline this, as I did, because working in smaller numbers makes me feel safer because I am a mathematical nincompoop. 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. 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.

Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.Americans, let's take it as a given that the whole rest of the world uses metric. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.Ĭ provides an online conversion calculator for all types of measurement units. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Its official symbol is 'bar' the earlier 'b' is now deprecated, but still often seen especially as 'mb' rather than the proper 'mbar' for millibars. The word bar is of Greek origin, báros meaning weight. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). bar to kilogram-force/square millimeter.Psia to bar, or enter any two units below: Enter two units to convert From:
