The SI unit of the pressure p = F / A (force F divided by area A) is the pascal, equivalent to N/m² (N = newtons).
Pascal is the SI unit for pressure and is derived from other SI units using the following relationship: Pa = (kg×m/s²)/m² = kg/m×s² = N/m². Since 1 pascal is a very low pressure being 1/100 of a millibar, it's use is limited to ultra low gas pressure applications such as measuring the pressure differences in ventilation systems.
The pascal is more commonly used as larger multiples of the unit which are the hectopascal (hPa), kilopascal (kPa) and the megapascal (MPa) unit, these are more practical when measuring mid range pressures.

Chemistry commonly uses atmospheres (ATM), torr, or mm Hg
1 ATM = 101,325 Pa = 760 torr = 760 mm Hg
For chemical calculations, Pa is an "ugly numbe

What is the derived unit of pressure in the SI?
pascal or newton/meter square
What is the SI for pressure which is equal to 1N exerted over 1m2?
That unit is also known as "Pascal".
Is newtons a unit of pressure?
No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
What is Force per unit area called?
That is called "pressure". The SI unit for pressure is the Pascal, equal to newtons per square meter.
What is the formula and SI unit for pressure?
The SI unit of pressure is Nm-2 which in words is newtons per metre squared. The units are derived from the equation for pressure which is P=F/A or pressure is equal to the force applied divided by the area over which that force is exerted.
What is a SI unit of pressure?
The appropriate measurement unit is a Pascal.
The SI unit of pressure is?
Pascal...
The pascal is the SI unit for?
Pressure.
What's the SI unit for pressure?
The Pascal
SI unit for pressure?
The SI unit for pressure is the pascal, which is equivalent to newton per square meter.
Is pascal a si unit?
Yes, it is the derived unit for pressure.
Whic unit measure atmospheric pressure?
The SI unit for pressure is the Pascal.
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.
Is pascal a unit of surface area?
No, it is not. Pascal is the unit (SI) of pressure. 1 Pascal=1 Newton/metre2
What is the SI unit it of pressure which is equal to 1 N exerted over 1 m2?
'Newton' is a unit of force, not pressure. They're different.The pressure on some area is the total force on the whole area divided by the area.The SI unit of pressure is the Pascal. 1 pascal of pressure means 1 newton of forcespread out over 1 square meter of area.
How do you calculate Pascal As in the SI unit for pressure?
Pressure [pascal] = force [newton] divided by area [m2].
What is the SI unit of pressure how is it defined?
The SI unit is the pascal, which is equivalent to a newton per square metre.
