si unit of pressure is pascal, which is equal to one newton per square metre.
si unit of pressure is pascal, which is equal to one newton per square metre.
si unit of pressure is pascal which is equal to?
one newton per square metre
combinations of base and derived units may be used to express other derived units. for example, the si unit of force is the newton (n), the si unit of pressure is the pascal (pa)—and the pascal can be defined as one newton per square metre (n/m).

the gas constant occurs in the ideal gas law, as follows:









































where "p" is the absolute pressure (si unit pascals), "v" is the volume of gas (si unit cubic metres), "n" is the amount of gas (si unit moles), "m" is the mass (si unit kilograms) contained in "v", and "t" is the thermodynamic temperature (si unit kelvins). "r" is the molar-weight-specific gas constant, discussed below. the gas constant is expressed in the same physical units as molar entropy and molar heat capacity.

from the ideal gas law "pv" = "nrt" we get:
