The unit of pressure, in SI units, is related to its unit in CGS units as

If force (F), velocity (V) and surface tension (S) were taken as the ‘fundamental units’, the dimensional formula, for momentum (p), would be

There are 20 divisions in 4 cm of the main scale. The vernier scale has 10 divisions. The least count of the instrument is

The ‘dimensions’, of the constant a, in the Van-der-wall equation of state $(p+\frac{a}{V^2})(V-b)=nRT\backslash left(p+\backslash frac\{a\}\{V^2\}\backslash right)(V-b)=nRT$ can be obtained by multiplying the dimensions, of the universal gas constant, G, by
