The amount of matter or stuff is measured by the mass, measured in kilogrammes and other units like grammes or pounds. It not the same as weight, which (if you are an astronaut) changes with where you are.
It depends on what you are measuring! Distance is measured in metres Time is measured in seconds Mass is measured in kilogrammes Volume is measured in litres Force is measured in newtons Energy is measured in joules Temperature is measured in kelvin Power is measured in watts Electromotive force is measured in volts Electric current is measured in amperes ...and so on
grammes and kilogrammes
It is a measure of mass, equivalent to 58,000 grams.
On Earth it weighs 20 kilograms.
The Newton is the unit of force, not of mass. Mass is constant but weight varies depending upon how and where this force is being measured. So, a context would be necessary to describe weight as measured in Newtons. Mercury's mass is 3.3 x 10^33 kilogrammes; if you were to weigh it at sea-level on Earth that would exert about 3.2 x 10^34 Netwons of force.

2000000 kilogrammes
A kilogram is a measure of mass with dimensions [M]. There is no such thing as a cubic kilogram.
Mass is measured in kilograms.
12 kilogrammes is larger in mass than 12 milligrammes by a factor of 1,000,000.
Mass is measured with a Triple Beam Balance. Yes it is.
