求初中物理的单位换算,比如100cm=1m.长度和面积,速度等等的换算

1km=1000m
1dm=0.1m
1cm=0.01m
1mm=0.001m
1um=0.000001m
1nm=0.000000001m
1h=3600s
1min=60s
1ms=0.001s
1us=0.000001s
1ns=0.000000001s
1ml=1cm2
1L=1dm2
1m|s=3.6km|s
1khz=1000hz
1kwh=3.6*1000000J
1kw=1000w
1mA=0.001A
1uA=0.000001A
1kv=1000v
1mv=0.001v
1kΩ=1000kΩ
1mΩ=1000000Ω
