The picometer conversion selector above selects the length/distance measurement unit to convert to starting from picometers (pm). To make a conversion starting from a unit of length other than picometer, simply click on the "Reset" button.
The picometer is a unit of length in the metric system equal to one trillionth of a meter (1 pm = 10-12 m), the base unit of length in the International System of Units (SI).
The picometer (pm) is also equal to 0.01 angstroms (Å) (a non-SI unit of length), or 0.001 nanometers (nm), or 10-6 micrometers (μm), or 10-9 millimeters (mm) or 10-10 centimeters (cm), which are SI units of length.
The picometer is used as a unit of measurement for dimensions in quantum physics and particle physics. For example, the diameters of atoms range from 62 pm to 520 pm.
Alternative names: picometre (plural: picometres, Int. spelling), micromicron (plural: micromicrons), stigma, or bicron
