About Chain
Gunter's chain equals 66 feet (20.1168 m) and underpins the US Public Land Survey System: 10 square chains make one acre.
Common uses: land surveying, cadastral records, cricket pitch length.
About Picometer
The picometer (pm) is a unit of distance and length. One picometer equals 1.000000 × 10^-12 metres. UnitConvertLab converts it against every other length unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: length calculations, engineering and science, education.
