Mass, Length & Time are fundamental physical quantity while velocity is derived physical quantity.

Temperature is one of the basic (fundamental) physical quantities.

CGS. units of density. is $g cm^{-3}$ where as in MKS unit it is $kg/m^3$.

We get Kilogram metre per second as the MKS units of force.

$1$ $hp = 745.699872 W$. 

Work done by a force   $W = FS$
Units of work   $W = kg.ms^{-2}\times m = kg \ m^2 \ s^{-2}$

The newton (symbol: N) is the International System of Units (SI) derived unit of force which is equivalent to $kg  m  { s }^{ -2 }$

1 joule (or 1J) is expressed in other SI units as $kg  { m  }^{ 2 } { s }^{ -2 }$

$1$ newton (or $1\ N$) is expressed in other SI units as $kg  m  { s }^{ -2 }$.

1 pascal (or 1Pa) is expressed in other SI units as $kg  { m }^{ -1 }  { s }^{ -2 }$
