What does Standard Atmosphere mean?

Standard Atmosphere is used as a unit of pressure.

Definition

Standard Atmosphere is defined as the pressure exerted by 760 mm of mercury at standard gravity and 0 °C temperature. It is approximately equal to the average atmospheric pressure at the sea level of Earth.

1 atm ≡ 101,325 Pa i.e. 1 Standard Atmosphere is equal to 101,325 Pascal

1 atm ≡ 1.01325 bar i.e. 1 Standard Atmosphere is equal to 1.01325 Bar

1 atm ≡ 760 Torr i.e. 1 Standard Atmosphere is equal to 760 Torr

1 atm ≡ 14.695 9 psi  i.e. 1 Standard Atmosphere is equal to 14.6959 Pound per square inch

What does Pressure mean?

Pressure is a kind of force. In the language of physics, a force is an object that changes or tries to change its state by acting on it or that changes or tries to change its motion by acting on a moving object.

For example, if someone pushes against a wall, the force is applied whether it changes its position or not. This effort is called force. On the other hand, the force exerted on a single area is called pressure.

This means that if we apply a force in a single case, it will be a force.

Pressure = (force ÷ area)

As an example, it is easy to take a photo with a pin because the area is less. Again, more pressure is required in the area.

The Unit of Pressure

Pressure scalar quantity, because it has value but has no direction. The SI unit of pressure is Pascal, which is equal to Newton per square meter (N/m²). Since an object or group of objects under pressure can act on its surroundings, the pressure is also measured as static energy in a single volume. It is related to the density of energy and can be expressed in joules unit per cubic meter (joules/m³, which is equal to Pascal). To make this concept precise, we use the idea of pressure. The pressure is defined to be the amount of force exerted per area.

Thanks for reading this article! Hopefully, it helps you understand what pressure is and how we measure the pressure of an object.

How to convert Millimetre of Water to Standard Atmosphere : Detailed Description

Millimetre of Water (mmH2O) and Standard Atmosphere (atm) are both units of Pressure. On this page, we provide a handy tool for converting between mmH2O and atm. To perform the conversion from mmH2O to atm, follow these two simple steps:

Steps to solve

Have you ever needed to or wanted to convert Millimetre of Water to Standard Atmosphere for anything? It's not hard at all:

Step 1

  • Find out how many Standard Atmosphere are in one Millimetre of Water. The conversion factor is 0.00009678411 atm per mmH2O.

Step 2

  • Let's illustrate with an example. If you want to convert 10 Millimetre of Water to Standard Atmosphere, follow this formula: 10 mmH2O x 0.00009678411 atm per mmH2O = atm. So, 10 mmH2O is equal to atm.
  • To convert any mmH2O measurement to atm, use this formula: mmH2O = atm x 0.00009678411. The Pressure in Millimetre of Water is equal to the Standard Atmosphere multiplied by 0.00009678411. With these simple steps, you can easily and accurately convert Pressure measurements between mmH2O and atm using our tool at Pyron Converter.

FAQ regarding the conversion between mmH2O and atm

Question: How many Standard Atmosphere are there in 1 Millimetre of Water ?

Answer: There are 0.00009678411 Standard Atmosphere in 1 Millimetre of Water. To convert from mmH2O to atm, multiply your figure by 0.00009678411 (or divide by 10332.274585156592).

Question: How many Millimetre of Water are there in 1 atm ?

Answer: There are 10332.274585156592 Millimetre of Water in 1 Standard Atmosphere. To convert from atm to mmH2O, multiply your figure by 10332.274585156592 (or divide by 0.00009678411).

Question: What is 1 mmH2O equal to in atm ?

Answer: 1 mmH2O (Millimetre of Water) is equal to 0.00009678411 in atm (Standard Atmosphere).

Question: What is the difference between mmH2O and atm ?

Answer: 1 mmH2O is equal to 0.00009678411 in atm. That means that atm is more than a 10332.274585156592 times bigger unit of Pressure than mmH2O. To calculate mmH2O from atm, you only need to divide the atm Pressure value by 0.00009678411.

Question: What does 5 mmH2O mean ?

Answer: As one mmH2O (Millimetre of Water) equals 0.00009678411 atm, therefore, 5 mmH2O means atm of Pressure.

Question: How do you convert the mmH2O to atm ?

Answer: If we multiply the mmH2O value by 0.00009678411, we will get the atm amount i.e; 1 mmH2O = 0.00009678411 atm.

Question: How much atm is the mmH2O ?

Answer: 1 Millimetre of Water equals 0.00009678411 atm i.e; 1 Millimetre of Water = 0.00009678411 atm.

Question: Are mmH2O and atm the same ?

Answer: No. The atm is a bigger unit. The atm unit is 10332.274585156592 times bigger than the mmH2O unit.

Question: How many mmH2O is one atm ?

Answer: One atm equals 10332.274585156592 mmH2O i.e. 1 atm = 10332.274585156592 mmH2O.

Question: How do you convert atm to mmH2O ?

Answer: If we multiply the atm value by 10332.274585156592, we will get the mmH2O amount i.e; 1 atm = 10332.274585156592 Millimetre of Water.

Question: What is the atm value of one Millimetre of Water ?

Answer: 1 Millimetre of Water to atm = 0.00009678411.
