What is the smallest unit of weight?

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

The smallest unit of weight ever recorded is the nanogram. This unit off weight is a mere fraction of a gram.

Answer 5

the smallest unit of length is plank's length.It is"1.616 199 multiplied by 10 minus 35 metres in size

Answer 6

The planck weight was proven to be the lowest weight. everything lower means nothing at all.

Answer 7

The yoctogram which is 0.000 000 000 000 000 000 000 001 grams.

Answer 8

less than nano gram
