The international system of units chooses seven independent quantities as basic quantities. The first is length. Its basic unit name is meter, the English abbreviation is m, and decimeter is not an international unit.
Conversion of length units:
10? Cm = 1 decimeter (dm)
100? Millimeter (mm) = 1 decimeter (dm)
10 decimeter (dm) = 1 meter (m)
0. 1 decimeter (dm)= 1 cm.
0.0 1 decimeter (dm) = 1 millimeter (mm)
10000 decimeter (dm)= 1 km.
Extended data:
Commonly used units are millimeter (mm), centimeter (cm), decimeter (dm), kilometer (km), meter (m), micron (micron), nanometer (nm) and so on. Length units play an important role in various fields.
The meter is the name of the SI-based wood length unit, and the units of physical quantities such as length, width, thickness, radius, perimeter and distance are all expressed in meters or their decimal multiples.
For example, centimeter is the unit for measuring length, gram is the unit for measuring mass, and second is the unit for measuring time. As an example of mathematics, it can also be said that 1 is the unit of natural number, and the fraction with the numerator of 1 is the unit of fraction.
