Water has a density of 1.94 slug/ft³. What is the density expressed in SI units? Express the answer to three significant figures.

Solution:

$\rho _w=\left(\frac{1.94\:slug}{1\:ft^3}\right)\left(\frac{14.59\:kg}{1\:slug}\right)\left(\frac{1\:ft^3}{0.3048^3\:m^3}\right)=999.6\:\frac{kg}{m^3}=1.00\:Mg/m^3$
