I have a silly question:
Is there anything smaller then a mm? i can't remeber
yes there is a micrometer,nanometer,picometer,femtometer,and attometer but that is as far as i can go
Yes, there are many units smaller than a millimeter. Going DOWN by a factor of 1000 for each, we have the following:
micrometer
nanometer
picometer
femtometer
attometer
zeptometer
yactometer
Here is a good web site.

No question is silly! And yes, there are units of measurement that are smaller than a millimeter (mm). In the metric system, the millimeter is one-thousandth of a meter. There are several smaller units used for extremely small measurements:
1. Micrometer (μm): It is one millionth of a meter or one thousandth of a millimeter. To visualize its size, the average diameter of a human hair is about 70 micrometers.
2. Nanometer (nm): It is one billionth of a meter or one millionth of a millimeter. It is often used in fields like nanotechnology, where the scale of objects being studied is extremely small. For example, a DNA molecule is about 2.5 nanometers in diameter.
3. Picometer (pm): It is one trillionth of a meter or one billionth of a millimeter. Picometers are commonly used in physics and chemistry to describe atomic and molecular scales. The size of an atom is typically a few picometers.
So, if you need to measure something smaller than a millimeter, you can consider using micrometers, nanometers, or even picometers, depending on the scale of the object or phenomenon you are dealing with.
