问几个物理换算的题
3.5cm= m= mm
36km= m= nm
37.5dm= m= um
70um= cm= mm
1.3h= min
4h24min= h
900s= min= ms
0.15s= ms= us
要用科学计数法啊...

3.5cm=3.5*10^-2m=3.5*10^2mm
36km=3.6*10^4m=3.6*10^13nm
37.5dm=3.75m=3.75*10^5um
70um=7*10^-3cm=7*10^2mm
1.3h=7.8*10^1min
4h24min=4.4h
900s=1.5*10^1min=9*10^5ms
0.15s=1.5*10^2ms=1.5*10^5us
3.5cm=3.5x10^(2) m=35 mm
36km= 3.6x10^4m= 3.6x10^13nm
37.5dm= 3.75m= 3.75x10^(-6)um
70um= 7.0x10^(-3)cm= 7.0x10^2mm
1.3h= 78min
4h24min= 4.4h
900s= 15min=9x10^5 ms
0.15s= 150ms= 1.5x10^5us
也不知道你用不用科学计数法~~
3.5cm= 0.035m= 35mm
36km= 36000m= 36000000000000nm
37.5dm=3.75 m= 3750000um
70um=0.007 cm=0.07 mm
1.3h= 80min
4h24min= 4.4h
900s= 15min= 900000ms
0.15s=150 ms= 150000us
3.5cm= 0.035m= 35mm
36km= 36000m= 3.6*10的13次方nm
37.5dm=3.75 m= 3750000um
70um= 0.007cm= 0.07mm
1.3h= 1.3*60=78min
4h24min= 4.4h
3.5cm= 0.035m= 35mm
36km= 3.6x10^4m= 3.6x10^13nm

70um=0.007cm=0.07mm
1.3h=78min
4h24min=4.4h
900s=15min=900000ms
0.15s=150ms=150000us
3.5cm=3.5x10^(2) m=35 mm
36km= 3.6x10^4m= 3.6x10^13nm
