Pressure is often measured in inches of Mercury when describing barometric pressure in weather reports. This term is also known as "inches of mercury vacuum".
There's no such thing as "mercury vacuum". A volume of space can have solid mercury, liquid mercury, or mercury vapor in it, or it can be a vacuum. The weight of the "standard atmosphere" on any area is the same as the weight of a column of mercury 29.92 inches high on that same area, with no air above the mercury.
It is vacuum
Yes, we are vacuum cleaners of the vacuum cleaners, which are the floor cleaners
The dielectric strength of vacuum is infinite because there is no molecule in the vacuum.
The "official" speed of light in a vacuum is 299,792,458 metres per second So in a millisecond - which is one-thousandth of a second - it will travel 299,792.458 metres. The Imperial equivalent of that is 186.2824 miles, or 186 miles, 495 yards, 5 inches.
18 to 21 inches of vacuum is a normal reading on a vacuum gauge.
You need a vacuum gauge and it is reed in inches.
30in is 762000 microns of vacuum
18 to 21 inches of vacuum is factory on all engines.
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
18 to 21 inches at idle
Your distributor needs vacuum to advance your timing during acceleration. That's why you hook up your line to the port that has no vacuum at idle. :O)

Quality vacuum gage is required ;-) engine at running temperature around 18 to 20 inches Hg = vacuum
That engine should have 18 to 21 inches of vacuum at an IDLE. You can find a vacuum source on the intake manifold.
18 to 21 inches.
hg is a measurement of Vacuum measured in Inches of Murcury.
