There are many units of pressure. Some common ones are:
The unit of pressure in SI is Pascal (equal to 1 N/m2).
For a table comparing the different units of pressure, refer to the related links.
Pressure is often measure in units of force per area. In the standard system of units, the SI, that would be Newton / meter2 - this unit is also called Pascal. Other commonly used units are bar (equal 100,000 Pascal), and atmosphere (the atmospheric pressure under standard conditions - close to one bar).
boost is pressure. units of pressure is pounds per square inch(psi), atmospheres (bar), and kilo pascals (kpa)

Systolic pressure is the upper number and diastolic pressure is the lower number.
In the SI system, because that's the way it is defined. Pressure is defined as force divided by area. SI units are newton / square meter, this derived unit is called the pascal. This is the way it is defined in the SI, and in some other systems of units. You could just as well create a system of units in which pressure is a base unit, and force is derived (as the product of pressure x area). The decision, which units are base units and which units are derived, is more or less arbitrary.
You can't convert between units of pressure and units of force (or mass).
It can be measured in N/cm2
Mega Pascal - measurement of pressure
The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.
The unit of pressure in SI is Pascal (equal to 1 N/m2).
