- Multiply by the conversion factor: 5 x 201.168
- The result is: 1,005.84 dm
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 Decimeter
The decimeter (dm) is a unit of distance and length. One decimeter equals 0.1 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.
