About Pressure Converter

Pressure is defined as the physical force exerted continuously on an object by something in contact with it. Specifically, it is the force applied perpendicular to the surface of an object per unit area. The International System of Units (SI) measures pressure in Pascals (Pa), but depending on the industry, you'll encounter a vast array of other units.

Atmospheric vs. Industrial Pressure

In everyday life, the most common pressure measurement in the US is PSI (Pounds per Square Inch), which dictates the inflation of car tires and basketballs. In meteorology, weather forecasters discuss barometric pressure dropping using millibars (mbar) or inches of mercury (inHg). In industrial piping and scientific settings, atmospheres (atm), Torr, and Bar are frequently used.

Common Use Cases

Automotive Maintenance: Converting the manufacturer's recommended tire pressure from Bar (used in European manuals) to PSI (used on US air compressors).
Scuba Diving: Calculating underwater pressure limits, where every 10 meters of depth adds roughly 1 Atmosphere (atm) or 1 Bar of pressure.
Meteorology: Pilots and meteorologists convert between millibars and inches of mercury to analyze high-pressure or low-pressure weather systems.

PSI stands for Pounds per Square Inch. It is the most common unit of pressure measurement used in the United States, frequently used for measuring car tire pressure, air compressors, and plumbing water pressure.

One standard atmosphere (1 atm) is defined as the baseline atmospheric pressure at sea level on Earth. It is equal to exactly 101,325 Pascals, 1.01325 bar, or approximately 14.6959 PSI.

One Bar is equal to exactly 100,000 Pascals (or 100 kilopascals). Because 1 Bar is very close to 1 standard atmosphere (1 atm), the two are often used interchangeably in general contexts, though they are mathematically slightly different.

This dates back to early barometers, which used a glass tube filled with liquid mercury. As atmospheric pressure increased, it pushed the mercury higher up the tube. Normal sea-level pressure pushes mercury up to about 29.92 inches.

Water is extremely dense. For every 33 feet (or 10 meters) you descend into the ocean, the pressure increases by exactly 1 Atmosphere (1 atm) or roughly 14.7 PSI.
