Unit Explanations

Barbar

Source Unit

The bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.

1 bar = 100,000 Pa

Current Use

The bar is widely used in various fields including meteorology for atmospheric pressure, and in industries such as automotive and aviation for tire pressure and cabin pressure monitoring. It is especially favored in contexts where moderate pressures need to be measured with a single-digit number, avoiding the unwieldy values that would result from using pascals.

Fun Fact

The bar is almost exactly the atmospheric pressure on Earth at sea level.

Centimeter of WatercmH₂O

Target Unit

A centimeter of water (cmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly 1 centimeter high at a specific temperature and gravity. It is commonly used in fields such as fluid mechanics and engineering, particularly for measuring low-pressure environments. The pressure generated is a result of the weight of the water column pressing down due to gravitational forces. This unit is particularly useful in applications where small pressure variations are significant, such as in medical devices and fluid systems.

P = ρgh

Current Use

Today, the centimeter of water is widely used in various industries, including medical, HVAC, and environmental engineering. It is particularly relevant in areas such as respiratory therapy, where pressure settings are critical for patient care, and in HVAC systems where pressure drop across filters is monitored.

Fun Fact

1 cmH₂O is approximately equal to 98.0665 pascals, making it useful for measuring low pressures.

Definition

The bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.

History & Origin

The bar as a unit of pressure was introduced in the early 20th century. It was created to provide a convenient metric unit for expressing pressures without having to resort to using large numbers, as can occur with the pascal. The bar was defined in 1909 by the International Union of Pure and Applied Chemistry (IUPAC) to be equivalent to 100,000 pascals, simplifying conversion with the SI system.

Etymology: The word 'bar' comes from the Greek word 'baros', meaning weight.

History & Origin

The centimeter of water as a unit of pressure emerged from the need to measure small pressures in fluid systems, particularly in the 19th century as engineering practices advanced. It was established to provide a practical measurement scale for pressure that could be easily understood and applied in various scientific fields.

Etymology: The term 'centimeter' comes from the French 'centimètre,' which is a combination of 'centi-' meaning one hundredth and 'metre' meaning measure. The 'water' part denotes the fluid used to create the pressure column.
