Pressure Unit Converter

To perform conversion between various pressure or stress units, start by selecting the original unit using the “From:” drop-down list and the target unit from the “To:” drop-down list. Then enter the original value into the input field on the left. The tool will instantly display the converted value at the top of the page.  

This converter supports the following  pressure or stress measurement units:

Newton/square meter (N/m²):

• The unit of pressure in the International System of Units (SI). It is defined as one newton of force per square meter. 1 N/m² = 1 pascal (Pa).

Atmosphere (standard) (atm):

• A unit of pressure based on the average atmospheric pressure at sea level on Earth. 1 atm is approximately equal to 101325 pascals.

Atmosphere (technical) (at):

• Another unit of pressure, often used in technical contexts. 1 atm is equivalent to 1.01325 bar.

Bar:

• A unit of pressure in the metric system. 1 bar is equal to 100,000 pascals.

Centimeter mercury (cmHg):

• A unit of pressure, commonly used in measuring blood pressure. It represents the height of a column of mercury in a barometer in centimeters.

Centimeter water (cmH₂O):

• A unit of pressure often used in fluid mechanics. It represents the pressure exerted by a column of water one centimeter high.

Decibar:

• A unit of pressure commonly used in oceanography, equal to one-tenth of a bar.

Kilogram-force/square centimeter (kgf / cm²) :

• A unit of pressure in the metric system, representing the force of one kilogram acting on one square centimeter. 1 kilogram-force/square centimeter equal  to 98066.5Pa.

Kilogram-force/square meter (kgf / m²):

• A unit of pressure in the metric system, representing the force of one kilogram acting on one square meter.  1 kilogram-force/square meter equal  to 9.80665Pa.

Kip/square inch  (kip / in²) :

• A unit of pressure in the imperial system, where a kip is a unit of force equal to 1000 pounds.

Millibar (mbar):

• A unit of pressure equal to one-thousandth of a bar, commonly used in meteorology.

Millimeter mercury (mmHg):

• A unit of pressure, often used in measuring atmospheric pressure. It represents the height of a column of mercury in a barometer in millimeters.

Pascal (Pa):

• The SI unit of pressure, defined as one newton per square meter.

Kilopascal (kPa):

• A metric unit of pressure equal to 1000 pascals.

Megapascal (MPa):

• A metric unit of pressure equal to one million pascals.

Poundal/square foot:

• A unit of pressure in the imperial system, where a poundal is the force required to accelerate one pound at one foot per second squared.

Pound-force/square foot (lbf / ft²):

• A unit of pressure in the imperial system, representing the force of one pound acting on one square foot.

Pound-force/square inch (lbf / in² or psi):

• A unit of pressure in the imperial system, representing the force of one pound acting on one square inch.

Torr:

• A unit of pressure, often used in vacuum measurements. It is defined as 1/760th of an atmosphere.
