Picometer is a length unit used to express distance, size or travel range in practical measurement work.
The prefix pico- (one trillionth) was adopted with the SI in 1960; the picometer is used for atomic radii and bond lengths.
Measurement system: Metric, imperial and internationally standardized length usage. SI equivalent: 1 pm = 1.000000e-12 m.
