The picometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: pm) or picometer ( American spelling) is a unit of length in the International System of Units (SI), equal to 1 × 10−12 m, or one trillionth ( 1 1 000 000 000 000) of a metre, which is the SI base unit of length.

The centimetre ( SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m ). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.

What is Pictometry & how does it work?
A picometre is a measurement. It is one millionth of a millionth of a metre. It is also one billionth of a millimetre. This is very small. Many atoms are larger than this. A picometer is 1×10−12 m (1 / 1,000,000,000,000 m). 1 picometer equals 0.001 nanometre , 0.01 angstrom or 1000 femtometre .
Pictometry. Pictometry is a patented aerial survey technique for producing oblique georeferenced imagery showing the fronts and sides of buildings and locations on the ground. Photos are captured by low-flying airplanes, depicting up to 12 perspectives (shot from a 40 degree angle) as well as an orthogonal (overhead) view of every location ...

The term micron and the symbol μ were officially accepted for use in isolation to denote the micrometre in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted μ, during the creation of the SI in 19...
The official symbol for the SI prefix micro- is a Greek lowercase mu. Unicode has inherited U+00B5 µ MICRO SIGN from ISO/IEC 8859-1, distinct from the code point U+03BC μ GREEK SMALL LETTER MU. According to the Unicode Consortium, the Greek letter character is preferred, but implementations must recognize the micro sign as well for compatibility wi...
Picotechnology. The term picotechnology is a portmanteau of picometre and technology, intended to parallel the term nanotechnology. It is a hypothetical future level of technological manipulation of matter, on the scale of trillionths of a metre or picoscale (10 −12 ). This is three orders of magnitude smaller than a nanometre (and thus most ...
