Mass, measured in kilograms is also called inertia (resistance to acceleration). Newton's second rule in its modern form... .... defines the mass of an isolated object, when force is in Newtons and acceleration is in m/s/s.
The kilogram is defined as the mass of a particular (unique) platinum iridium cylinder kept in a vault at Servrés near Paris for the last three hundred years. |

The four quantities defined in the MKSA system are the meter, kilogram, second and Ampere. |
