Question

What is diamention of pressure physical quantity? ​

Answer 1

Answer:

The unit of a physical quantity follows from the dimension expression. For example, since velocity has dimension [LT−1] and length is measured in m while time is measured in s, the unit for velocity becomes m/s. Similarly, force has dimension [MLT−2] and unit kg\, m/s2. The k parameter in (1) is measured in kg\,s−2
