Length conversion 9um=_______ m 4.8km=————m_____ nm 520cm=_______ m 168nm=_______ dm 0.28km=_______ m=______ cm 83um=_______ nm=______ m

9um =9×10^(-6)m
4.8km=4800m=4.8×10^12nm
520cm=5.2m
168nm=1.68×10^9dm
0.28km=280m=28000cm
83um=83000nm=0.000083m

Conversion between physical lengths

1km = 1000m, 1m = 10dm, 1dm = 10cm, 1cm = 10mm, 1mm = 1000 μ m, 1 μ M = 1000 nm
