A femto is in metric prefix terms a quadrillionth, whereas a centimeter is a hundredth. The femto was added in 1964 and was derived from the word femten meaning 'fifteen'.
'Nano-' is 10-9, if that's what you mean. 'Pico-' is 10-12. 'Femto-' is 10-15.
In the metric system, the units atto, femto, and pico are related by their respective powers of 10. Atto is 10-18, femto is 10-15, and pico is 10-12. This means that atto is smaller than femto, which is smaller than pico.
I think you pico rather than pica. The prefix pico- represents a factor of 10-12, or 0.000 000 000 001. The next smallest prefix is femto- 10-15, or 0.000 000 000 000 001. Pico- is one step down from nano- which is 10-9, 0.000 000 001.

your teeth comes out and its just there, just deal with the fact its there.
well, if you think about it, it is infinite. the furthest I know is exa, tera, giga, mega, centa, deca, deci, centi, milli, micro, nano, pico, femto, atto. so, did that help?
There are 10-15 seconds in a femtosecond.
Femto is 10-15, atto is 10-18 for a start
Femto is a prefix (see all prefixes) to a unit and means that it is 10-15 times this unit, or, one quindecillionth (European) or one quadrillionth (American). Examples are one femtosecond or one femtometre.
Its a quadrillionth of a unit (3 more zeros than a trillion has)
