This depends what you are measuring.
The metric system uses prefixes to change the size of units.
Litres can have the prefix milli. Millilitres are a thousandth of a litre.
Similarly, millimetres are a thousandth of a metre.
Other prefixes are:
micro = 1/1 000 000; 10-6
nano = 10-9
pico = 10-12
femto = 10-15
There is no smallest metric unit of mass.
Mass is only in kg (kilograms).
But there might be several prefixes depending is value greater or smaller then kg.
So you can use milligram (10^-3), microgram (10^-6), nanogram (10^-9) etc...
Smallest prefix from a SI table would be yoctogram (10^-24 kg) but since it's very rare it can be just used 10^-24 kg or, by the same principle, you can use smaller (or every other prefix) as 10^-28, 10^-16 regardless prefix name.
The smallest unit of weight that has a name is a picogram, which is 1/1000th of a nanogram.
1 gigatonne(Gt)=1 000 000 000 000 000 g
1 megatonne(Mt)=1 000 000 000 000 g
1 tonne(t)=1 000 000 g
1 kilogram(kg)=1 000 g
1 gram(g)=1 g
1 milligram(mg)=0.001 g
1 microgram(µg)=0.000 001 g
1 nanogram(ng)=0.000 000 001 g
1 picogram(pg)=0.000 000 000 001g
The smallest unit of weight ever recorded is the nanogram. This unit off weight is a mere fraction of a gram.
the smallest unit of length is plank's length.It is"1.616 199 multiplied by 10 minus 35 metres in size
The planck weight was proven to be the lowest weight. everything lower means nothing at all.
The yoctogram which is 0.000 000 000 000 000 000 000 001 grams.
less than nano gram
cell
The smallest unit of a chemical element is the iron.
A cell is the smallest unit of life
The smallest unit of matter is an atom, which is made up of protons, neutrons, and electrons. Protons and neutrons are made up of quarks, while electrons are thought to be fundamental particles.
The cell is the smallest unit.
yes
If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.
This smallest unit is the atom.
A cell is the smallest unit of an organism
Smallest unit of a compound is a molecule.
A molecule is a compounds smallest unit
