There are several units of measure to use while dealing with vacuum.
The absolute units start from full vacuum then approach atmospheric pressure.
The "Gauge" ones use atmospheric pressure as a baseline- but Atm. Pressure varies with each day, with altitude, temperature and even with Hurricanes.
Some absolute units are: Torr, Millitorr, Mbar
Some "Gauge" units are: "Hg, Psig, "H20 (inches of water)

I don't know, ask google!
This ratio is called the specific gravity.
why are vacuum flasks called vacuum flask
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
This is called absolute zero. The temperature is 0 Kelvin or -273.15 degrees Celsius.
THEORETICALLY: An absolute vacuum has no mass contained. In empty space there is no mass, so an absolute vacuum is empty space and empty space is an absolute vacuum. There is no difference. Although, there may be energy passing through the empty space or vacuum in the form of electromagnetic waves, or gravitational or magnetic fields.
That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.
no number; absolute value is always positive. The absolute value of a negative number is positive. For example absolute value of -4 is +4
The absolute value of 19 is 19. If x is positive , absolute x equals x.
Depends on If it's absolute or relative. Vacuum in any unit is zero in absolute pressure. Vacuum in any unit is -normal air pressure in relative pressure.
An interger's absolute value is how far away it is from 0, so an interger's absolute value will always be positive. The absolute value of -83 is 83. The absolute value of 178 is 178. etc.
Absolute value is the distance of a number from zero on a number line.
The absolute value is when even if a negative number when put in absolute value signs is positive such as.. l-23 l the absolute value is 23. l..l are absolute value signs
the absolute value of negative 7 is 7 and the absolute value of 7 is also seven so they are equal. Therefore, the absolute value of negative 7 is not less than the absolute value of 7. Remember that absolute value means the positive of a number
Absolute value of 14 is 14.
The absolute value of something is its difference from 0. Absolute value of -607=607
They are the same. the absolute value is always positive
