One Pascal is the pressure exerted by a force of one newton, normally on an area of one square meter. Atmospheric pressure is the force per unit area by the weight of air on a point. One atmospheric pressure is related with the Pascal as: \(1 \,atm =101325 \,Pa\)
The prefix \(10^{18}\) is Exa. Its symbol is \(E\). Giga \((G)\) represents \(10^9\). Nano \((n)\) represents \(10^{-9}\). Kilo represents \(1000\). Thus, \(1 \,kg =1,000\, g\)

Explanation:
as all non-zero digits are significant and the zeros at the beginning of a number are not significant. the zeros trailing decimal point are not significant. Therfore number \(161 \,cm , 0.161 \, cm\) and \(0.0161 \,cm\) have \(3,3\) and \(3\) significant figures respectively
