### What does Centimeters of Mercury mean?

CmHg, or centimeters of mercury, is a unit of pressure commonly used in medical and scientific contexts. It is based on the height of a column of mercury in a barometer, with one centimeter of mercury representing the pressure exerted by a column of mercury one centimeter in height.

CmHg is often used to measure blood pressure, with the systolic pressure (the pressure in the arteries during a heartbeat) and diastolic pressure (the pressure in the arteries between heartbeats) reported in units of mmHg (millimeters of mercury). For example, a blood pressure reading of 120/80 mmHg indicates a systolic pressure of 120 mmHg and a diastolic pressure of 80 mmHg.

CmHg is also commonly used in the field of respiratory medicine to measure lung function. In this context, it is used to measure the amount of pressure that a person can generate when exhaling forcefully, known as the forced expiratory volume in one second (FEV1). The FEV1 is typically reported in units of liters per second, but it can also be reported in units of cmHg, with one liter per second approximately equal to 10 cmHg.

CmHg is a useful and widely recognized unit of pressure, but it is important to note that mercury is a toxic substance and can be dangerous if it is not handled properly. In recent years, there has been a shift towards using alternative units of pressure that do not involve the use of mercury, such as kilopascals (kPa) or millimeters of water (mmH2O).

### What does Millimetre of Mercury mean?

Millimeters of mercury (mmHg) is a unit of pressure measurement that is commonly used in medicine and meteorology. It is also known as millimetres of water column, which is abbreviated as mmWC.

The mmHg unit is defined as the amount of pressure exerted by a column of mercury that is 1 millimeter high and has a density of 13.5951 g/cm³, which is the density of mercury at 0°C. This unit of pressure is used extensively in medicine, especially in the measurement of blood pressure.

To understand the concept of mmHg, it is important to first understand what pressure is. Pressure is the amount of force exerted per unit area. In the case of mmHg, it is the amount of force exerted by a column of mercury that is 1 millimeter high.

The normal range for blood pressure in adults is around 120/80 mmHg. This means that the pressure exerted by the blood in the arteries when the heart beats (systolic pressure) is around 120 mmHg, and the pressure exerted when the heart is at rest (diastolic pressure) is around 80 mmHg.

In addition to medicine, mmHg is also commonly used in meteorology to measure barometric pressure, which is the pressure exerted by the Earth's atmosphere. Barometric pressure is an important factor in weather forecasting as it helps predict weather patterns and changes.

Another unit of pressure measurement that is commonly used is the kilopascal (kPa). To convert mmHg to kPa, the following equation is used: 1 mmHg = 0.133 kPa.

In summary, millimeters of mercury (mmHg) is a unit of pressure measurement that is commonly used in medicine and meteorology. It is defined as the amount of pressure exerted by a column of mercury that is 1 millimeter high and has a density of 13.5951 g/cm³. This unit is used extensively in the measurement of blood pressure and barometric pressure.

### 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.

### How to convert Centimeters of Mercury to Millimetre of Mercury : Detailed Description

Centimeters of Mercury (cmHg) and Millimetre of Mercury (mmHg) are both units of Pressure. On this page, we provide a handy tool for converting between cmHg and mmHg. To perform the conversion from cmHg to mmHg, follow these two simple steps:

Steps to solve

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

Step 1

• Find out how many Millimetre of Mercury are in one Centimeters of Mercury. The conversion factor is 10.0 mmHg per cmHg.

Step 2

• Let's illustrate with an example. If you want to convert 10 Centimeters of Mercury to Millimetre of Mercury, follow this formula: 10 cmHg x 10.0 mmHg per cmHg = mmHg. So, 10 cmHg is equal to mmHg.
• To convert any cmHg measurement to mmHg, use this formula: cmHg = mmHg x 10.0. The Pressure in Centimeters of Mercury is equal to the Millimetre of Mercury multiplied by 10.0. With these simple steps, you can easily and accurately convert Pressure measurements between cmHg and mmHg using our tool at Pyron Converter.

FAQ regarding the conversion between cmHg and mmHg

Question: How many Millimetre of Mercury are there in 1 Centimeters of Mercury ?

Answer: There are 10.0 Millimetre of Mercury in 1 Centimeters of Mercury. To convert from cmHg to mmHg, multiply your figure by 10.0 (or divide by 0.1).

Question: How many Centimeters of Mercury are there in 1 mmHg ?

Answer: There are 0.1 Centimeters of Mercury in 1 Millimetre of Mercury. To convert from mmHg to cmHg, multiply your figure by 0.1 (or divide by 10.0).

Question: What is 1 cmHg equal to in mmHg ?

Answer: 1 cmHg (Centimeters of Mercury) is equal to 10.0 in mmHg (Millimetre of Mercury).

Question: What is the difference between cmHg and mmHg ?

Answer: 1 cmHg is equal to 10.0 in mmHg. That means that cmHg is more than a 10.0 times bigger unit of Pressure than mmHg. To calculate cmHg from mmHg, you only need to divide the mmHg Pressure value by 10.0.

Question: What does 5 cmHg mean ?

Answer: As one cmHg (Centimeters of Mercury) equals 10.0 mmHg, therefore, 5 cmHg means mmHg of Pressure.
