Supposed to get to the mid 80's today.

It's been utterly divine here lately.

[edna]

It's cold here.

[The Seeker]

Here too.

[Levis]

here three.

I'm so confused...

[Kevin]

You're loving that cold , eh , Dehli -girl ? Go get 'comfy ' .

[RonJonSurfer]

Summer is still hangin on...80 plus today.

what kind of unit is that btw? inch?

for air pressure I only know (hecto)pascal and (milli)bar

in = inch

Normally I post in both English and Metric, but I forgot.

[Farin]

don't worry about that

I was just curious how air pressure can be measured in a unit of length...

Quite simply; atmospheric pressure can either be measured in inches of mercury or in millibars. 29.92 inches of mercury is equal to 1013.25 millibars. Pressure is basically defined as force per unit area. Inches are a unit of area.

In a barometer, there's a rod of mercury, usually about 33 inches long.

Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir.

that's interesting, I never heard of that

on the other hand, the inch refer to the column of mercury, not the pressure itself (inch isn't a unit of area either )

thanks for explaining

I'm aware of that, that's what I said. It's the measurement on the rod of mercury that determines the pressure. And an inch is a unit of area. Area = length x width x height and all those things can be measured in inches.
