Okay, when we're converting 235 millimeters of mercury into tor, we're going to be using this and this conversion.
00:10
So we're going to take 235 millimeters of mercury, and then on the diagonal, you're going to have 760 millimeters of mercury, and then 760 tor on the top.
00:24
The millimeters of mercury will cancel.
00:26
Obviously, 760 over 760 is 1, so you're really multiplying by 1.
00:31
So this becomes 235 tor.
00:34
For psi, we're going to convert from millimeters of mercury here over to psi here.
00:41
We don't have to stop off through tor to get there.
00:44
So we're going to take 235 millimeters of mercury.
00:49
And then on the diagonal, you'll have 760 millimeters of mercury.
00:53
And on the top, you're going to have 14 .7 psi, millimeters of mercury will cancel.
01:01
So 235 times 14 .7 divided by 760.
01:05
We're going to round this off to three significant figures.
01:08
This is going to be 4 .55 psi...
