I have a silly question:

Question

Is there anything smaller then a mm? i can't remeber

Answer 1

yes there is a micrometer,nanometer,picometer,femtometer,and attometer but that is as far as i can go

Answer 2

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.
