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)

What is absolute value in chemistry?
In chemistry, absolute value is a term used to describe the positive value of a quantity, regardless of its sign. For example, the absolute value of -5 is 5. It is used in calculations involving properties such as temperature, concentration, or energy.
Why absolute value of enthalpy of system cannot be measured?
The absolute value of enthalpy cannot be measured because enthalpy is a state function, which means its value depends on the initial and final states rather than the absolute value. Only changes in enthalpy can be measured experimentally through processes like calorimetry.
The ratio of the weight of a given volume of a substance in a vacuum at a given temperature to the weight of an equal volume of water in a vacuum at a given temperature is known as?
This ratio is called the specific gravity.
What is the percent error in the measurement of the density of a substance, rounded to the appropriate number of significant figures?
The percent error in the measurement of density is calculated by taking the absolute difference between the measured value and the accepted value, dividing it by the accepted value, and then multiplying by 100. The result is rounded to the appropriate number of significant figures.
Why are vacuum flasks called vacuum flasks?
Vacuum flasks are named so because they have a double-wall design with a vacuum-sealed space between the walls. This vacuum insulation helps to minimize heat transfer by conduction or convection, keeping hot liquids hot and cold liquids cold for an extended period of time.
Distance a number is from zero?
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.
What number has the absolute value as -4?
no number; absolute value is always positive. The absolute value of a negative number is positive. For example absolute value of -4 is +4
Is there a difference between empty space and an absolute vacuum ie Does an absolute vacuum posses a Higg's field?
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.
What is the absolute value of -19?
The absolute value of 19 is 19. If x is positive , absolute x equals x.
Information about absolute value?
Absolute value is the distance of a number from zero on a number line.
What is the integer's absolute value?
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.
What is absolute value and why is it useful?
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
What is the absolute value of-607?
The absolute value of something is its difference from 0. Absolute value of -607=607
What is the absolute value of 14?
Absolute value of 14 is 14.
How does the absolute value of -7 compare to the absolute value of 7?
They are the same. the absolute value is always positive
What is an absolute function?
The absolute value function returns the absolute value of a number.
Is the absolute value of negative 7 less than the absolute value of 7?
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
