I saw a planck length once. But I don't like to boast about it.
A millimeter is 25.4 times smaller than one inch.
A milligram is ten times smaller than a centigram.
Pretty small. Although the exact mass of these particles (there are three "flavors" of neutrinos) is unknown, the maximum possible mass of the heaviest possible neutrino is about a millionth of the mass of an electron.
In the SI, the usual SI prefixes would be used for smaller units - prefixes such as milli, micro, etc.
The "Planck units" are generally the smallest units used - except for the Planck unit for mass, which is fairly large.
a pico second
The electron has not other components, it is a fundamental particles. But neutrinos are smaller than the electron.
No, it cannot be smaller than a smaller unit!
a femto second is 1000 times smaller 10-15 an atto second is 1000000 times smaller 10-18 According to current thinking, one Planck time = 5.39 * 10-44 seconds is the smallest unit of time that it will ever be possible to measure.

Yes, the unit grams is smaller than the unit kilograms.
A microgram is the unit which is smaller than a milligram.
An attosecond is one quintillionth (10 to the power of minus 18) of a second. As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times. In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
1/2 unit, 1/4 unit,
There is no metric unit smaller than a millimeter. But , there are many other units which are smaller than mm . those are : nanom , picom , micrometer, fero meter ,etc.
Because the number of larger units will be less than the number of smaller units, and when you divide the answer is usually smaller than the number you started with.
