At least one use of femto- is in pulsed laser physics. Laser pulses of 50 femtoseconds can precisely remove material one atomic layer at a time without heating the surroundings. They can laser cut explosives without setting them off.
Its in the SI system known as the metric system
You need to state what pico relates to. For instance one picocoulomb is 1x10-12 coulomb.
1 Pico Gram = 1 x 10^-12 Grams
Pico means 1/1,000,000,000,000. Micro means 1/1,000,000. Therefore there are 1,000,000 picograms in a microgram.
"pico..." = 10-12 (one trillionth) 1 second = one trillion picoseconds = 1012 picoseconds = 1,000,000,000,000 picoseconds
They are different prefixes for amounts less than unity:kilo = 1/1000micro = 1/1,000,000nano = 1/1,000,000,000pico = 1/1,000,000,000,000
The prefix "pico" means ten to the power -12; 1 divided by that is 10 to the power 12.This applies whether you use the prefix "pico" with meters, seconds, or any other measure.
The prefix pico refers to 1x10-12 of a unit.
Pico means 10-12 = 0.000000000001
Pico (symbol p) is a prefix in the metric system denoting one trillionth.

It indicates 10-12 of a unit.
"Micro micro" was an older designation used for a metric prefix that is now known as the prefix "pico," which represents one trillionth (1/1,000,000,000,000). The use of "micro micro" was eventually replaced by the standardized SI prefixes to avoid confusion.
Pico- (symbol p) is a prefix in the metric system denoting one trillionth, a factor of 10^−12 (0.000000000001).
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.
It's pico, and it is 10-12
