100 psi = 6.89475729 Bar
Wow, everyone should be using metric, this is so much easier!
are you stupid or sarcastic?
Stucastic! I knew it!
pheww i thought i was talking to an american for a sec
I was also confused about this, and started to make a comment about it, then I remembered that this post is on the Shitposting community, and dropped it
yes
The unit of pressure in the SI is, in fact, the pascal. 100 psi = 689.5 kPa. For whatever reason we use bars for the tyres, tho. My car tyres run at 2.3 bar, which is a nice and easy number to remember not like the equivalent 33.358679678 psi, so ugly and difficult.
Me when some projects I've been on decide to use bar as the preferred unit with two decimal places typically shown: My sibling in engineering, at that point why not just use whole number kPa 😢
SI master race.
Of course I'll take bar any day over anything non-metric.
* Cries in practically all valve manufacturers using imperial valve coefficients. 😭😭😭 *
Or 689kpa.
Yeah seriously with 100 psi it’s all zeros after the decimal. Look how precise you can get when you convert to bar.
6 bar is 87.022642638 psi. What's your point? Metric is superior in every way. Nearly the entire world was smart enough to come to that conclusion.
Check the community
You might be missing a few decimal points there. It's not precise enough.
I'd argue it's inferior for estimating by eye and dividing in half.
Jesus. My bike tires have less than that.
I think race bicycles are around 6-7 bars. Is there a risk there?
Much smaller tire, and so much less stored energy
They're made for those pressures. Most normal car tires aren't.
Thin tires get high pressures to account for narrow points of contact. Tires are designed with this in mind. Now picture putting 6 bars in a fat tire, that bike won't be happy.
