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'.
no; however, femto- is an SI prefix meaning 10-15
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.
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.

Femto is the SI prefix standing for 10-15, kilo is the prefix for 103. so the difference between kilo and femto is 3-(-150) or 3+15 = 18. So there are 1018 fg in one kg. That is 1 000 000 000 000 000 000 femtogram.
Quite a lot of things are. Any gram quantity with the prefix nano, pico and femto, i.e. nanogram, picogram, femto, and indeed atto even are smaller than a microgram. In a microgram, there are 1000 nanograms, 1000000 picograms, 1000000000 femtograms, 1000000000000 attograms.
pico- is a prefix that can be added to any measurement to mean divide by 1,000,000,000,000. femto- is smaller and means / 1,000,000,000,000,000. atto- is even smaller and means / 1,000,000,000,000,000,000.
Pico refers to 10^-12; femto is a thousand times less, atto is a thousand times less than that, then zepto, and finally yocto at a whopping 10^-24
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.
