# Derive the dimensional formula for pressure.

##### SOLUTION
$Pressure = \dfrac{Force}{Area}$

$= \,\dfrac{{M\, \times \,\frac{{velocity}}{{Time}}}}{{{{\left( {length} \right)}^2}}}$

$= \,\,\dfrac{{M \times \,\frac{{length}}{{time\, \times \,time}}}}{{{{\left( {length} \right)}^2}}}$

$= \,\dfrac{M}{{{{\left( {time} \right)}^2}\, \times \,length}}$

$= \,\dfrac{M}{{{T^2}\, \times \,L}}$

$= \,M \,{L^{ - 1}}\,{T^{ - 2}}$

You're just one step away
