问题描述:
单位换算:7.5km=___m;5.85mm=___m;0.068m=___nm;16.4m=___微米;1.8h=___min;45min=___h.
答
7.5km=_7500__m;5.85mm=__0.00585_m;0.068m=__6.8*10^7_nm;16.4m=_1.64*10^7__微米;1.8h=_108__min;45min=__0.75_h.
答
7.5km=7500m
5.85mm=0.00585m
0.068m=68000000nm
16.4m=16400000微米
1.8h=108min
45min=0.75h
参考:
1 微米=1000 纳米(nm)
1 毫米(mm)= 1000 微米=1000000纳米
