Pressure is a measure of force per area.
The SI unit of pressure is a Pascal (Pa) which is equivalent to a Newton per meter squared (N/m2).

What is the SI unit of pressure. What units of pressure are commonly used in the US Why are these common units more convenient to use than the SI unit?
SI unit is the Pascal. The US uses psi (pound per square inch). The last q depends a little on who is asking. It does have the advantage of showing the components. Pascal is equal to a Newton per meter cubed which is not obvious by looking at unit. I suppose its also better for measuring pressures over smaller volumes.
What is the unit of measuring atmospheric pressure?
Millibars. Inches of mercury or feet of water
What is value of R In the ideal gas law?
0.0821 L·atm/mol·K -Apex
Why is SI base units in science?
The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units are derived. These SI base units and their physical quantities are:[1]metre for lengthkilogram for masssecond for timeampere for electric currentkelvin for temperaturecandela for luminous intensitymole for the amount of substance.The SI base quantities form a set of mutually independent dimensions as required by dimensional analysis commonly employed in science and technology. However, in a given realization of these units they may well be interdependent, i.e. defined in terms of each other.[1]The names of all SI units are written in lowercase characters (e.g. the metre has the symbol m), except that the symbols of units named after persons are written with an initial capital letter (e.g. the ampere has the uppercase symbol A).Many other units, such as the litre, are formally not part of the SI, but are accepted for use with SI
The different between si units and metric units?
Si and metric are the same thing. SI was a redefinition of metric in 1960.
Why should si units be used instead of other units?
There are different units for measuring different attributes.
What are the fundamental and derived units?
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
Importance of SI units?
SI units are important because it is a universal means of communicating different types of measurements.
What is the units for Pressure?
The unit of pressure in SI is Pascal (equal to 1 N/m2).
The product of pressure and volume has the same si base units as?
Energy
Why is pressure a derived quantity?
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.
What are the three basic si units of measurement?
There are not three, but seven base units in the SI. See the list here: http://en.wikipedia.org/wiki/SI_base_units The first three in the list are the ones used in mechanics.
What is the SI derived unit for pressure?
In SI system of units the pressure has the unit: N m^-2. The same has been noted as pascal just in the memory of the scientist Pascal.
How does SI help scientists in different part of the world?
By knowing the SI units of length,mass,liquid,and other SI units helps them figure out stuffs
2 units of mass?
There are several different units of mass used. Grams, kilograms, and milligrams are all different SI units of mass.
How can if different units are used in measurement problems be overcome by using SI unit?
If you have different units, converting to any common unit will help. Of course, using standard units, i.e. SI units, is better than any other arbitrary unit. Also, SI units for a consistent set of units; as a result, you can often omit proportionality factors from formulae.
