8814.6dm= um?0.000037km= dm?687um= 0.0096nm= cm?37690um= km?128cm=m?236m=dm?

我告诉你换算关系,自己算
1km =1000m =10^3m
1dm =0.1m =10^-1m
1cm =0.01m =10^-2m
1mm =0.001m =10^-3m
1um =0.001mm =10^-6m
1nm =0.001um =10^-9m

1km= m= dm= cm= mm= um= nm 1M= KM= DM= CM= MM= UM= NM 5×10^-3m=( )um 8.6×10^7cm=( )km 4dm=( )nm 15cm=()um=()nm 35nm=()mm=()km 270dm=()nm=()um 5min=()s=()h 0 1m=( )dm=( )cm=( )um=( )nm 1dm=( )mm=( )cm=( )nm=( )um 1.7dm= cm= mm nm um 350um=多少m?,10um=多少nm?,25dm=多少km?,2×10的负二次方=多少cm? 4.76X10的-5次方km= m= dm= um= nm 4.2nm=?cm 6.7dm=?km 0.18=?m 7dm=?cm=?mm=?nm=?um 20min=?h 0.5 3.6km= m= dm = cm 3.2= m= um 1um等于多少nm ,cm,km,mm dm,m
