The letter representation of centimeter is: cm
This is the unit of length: meter----m, decimeter----dm, centimeter----cm, millimeter ----mm, kilometers----km.
Light-year, photometer (Pm), megameter (Mm), kilometer (km), decimeter (dm), centimeter (cm), millimeter (mm), silk meter ( dmm), centimeters (cmm), micrometers (μm), nanometers (nm), picometers (pm), femtometers (fm), ammi (am), etc.
Their conversion relationship with meters is as follows:
1 light year = 9.46PM (approximately, light year)
1Mm=1×10^6m (megameter)
< p>1km=1×10^3m (kilometer)1dm=1×10^(-1)m (decimeter)
1cm=1×10^(- 2)m (centimeter)
1mm=1×10^(-3)m (millimetre)
1dmm=1×10^(-4)m (silk meter)< /p>
1cmm=1×10^(-5)m (hurt meter)
1μm=1×10^(-6)m (micrometer)
1nm =1×10^(-9)m (nanometer)
1pm=1×10^(-12)m (picometer)
1fm=1×10^(- 15)m (femt)
1am=1×10^(-18)m (ami)
