## Bar

### Definition

The bar is a non-SI unit of pressure derived from the atmospheric pressure at sea level, equal to 100 kilopascals. It was originally defined as “the atmospheric pressure that will support a column of mercury 760 millimeters high at 0 degrees Celsius”.

### Origin

The bar was introduced in 1814 by French physicist André-Marie Ampère. It is derived from the atmospheric pressure at sea level, which can vary depending on location and altitude.

In addition to its use as a unit of pressure, the bar has also been used as a unit of length since the 19th century; this unit is unrelated to pressure measurement, however, and should not be confused with it.

### Application

The bar is used in many different industries to measure pressures greater than one atmosphere. These include aviation and car engineering, meteorology and oceanography (to measure barometric pressure), scuba diving (to measure water depths greater than 10 meters), and other scientific settings like physics labs or medical equipment.

Despite the introduction of the **SI** unit of pressure, the pascal, in 1978, the bar is still used extensively in many areas due to its historical prevalence. It is important to remember that bar and pascal measurements are not interchangeable and must be converted appropriately when dealing with different units of pressure.

For example, a scuba diver should always use bars for depth readings; if a depth gauge reads “3 bars,” this equates to 300 meters (984 feet). If it were expressed in Pa, it would need to be multiplied by 100,000 and divided by 101,325 to get an accurate reading in meters or feet. Similarly, when measuring atmospheric pressures like barometric pressure, Pa should be used instead of bar.

Now, let’s have a look at **Psi**.

## Psi

### Definition

The pound-force per square inch (psi) is a unit of pressure used in the imperial and US customary systems. It is measured by how much pressure is put on an area of one square inch by a force of one pound-force. The psi can be converted into other units such as pascals (Pa) by multiplying it by 6,894.75729 or dividing it by 144; conversely, 1 Pa is equal to 0.000145037738 psi, so psi can be calculated by multiplying Pa by this number.

### Application

The pound-force per square inch is widely used across many industries, including automotive engineering and hydraulic equipment, tire and rubber manufacturing, oil drilling and production, plumbing fixtures and appliances, and natural gas distribution. It is also used to measure the pressure of gases in refrigeration systems and air-conditioning equipment.

In addition, psi is commonly used for measuring pressures greater than one atmosphere in scuba diving; so a diver reading “20 psi” would be equivalent to a pressure of 1.3 bars or 130 m (424 ft) of seawater depth. As with the bar, it’s important to note that different units of pressure like psi should not be interchanged without first converting them appropriately.

### Origin

The psi was first used in the 19th century and is derived from the pound-force, which is a unit of force that has been part of the imperial system since 1799. It was originally defined as the weight exerted by a one-pound mass at sea level.

In conclusion, both bars and psi are important units of pressure but should not be interchanged without first converting them appropriately. To ensure accurate readings, it’s best to use the appropriate unit for each context; for example, when measuring atmospheric pressures like barometric pressure, Pa should be used instead of either bar or psi. By understanding how to convert between different measurements of pressure correctly, you can ensure that your results are precise and reliable.

## F.A.Q Bar to psi

### What is the psi of 1 bar?

1 bar is equal to 14.5037738 PSI (pounds per square inch). To convert bar to psi, multiply the bar unit by 14.5037738. For example, 1 bar = 14.5037738 PSI (14.5037738 x 1 = 14.5037738).

### What is 2 O bar in psi?

2 O bar is equal to 29.0075476 PSI (pounds per square inch). To convert 2 O bar to psi, multiply the 2 O bar unit by 14.5037738. For example, 2 O bar = 29.0075476 PSI (14.5037738 x 2 = 29.0075476).

### How much kg is 1 bar?

1 bar is equal to 100,000 kg (kilograms). To convert 1 bar to kg, multiply the bar unit by 100,000. For example, 1 bar = 100,000 kg (100,000 x 1 = 100,000).

### How much psi in 1 kg?

1 kg is equal to 0.0000145037738 psi (pounds per square inch). To convert 1 kg to psi, divide the kg unit by 6894.75729. For example, 1 kg = 0.0000145037738 PSI (6894.75729 ÷ 1 = 0.0000145037738).

## Conclusion

In conclusion, bar to psi conversion is a complex mathematical process that requires time and energy to solve. It involves taking the appropriate units of measure and applying four simple steps in order to accurately convert from one unit to another.
