1km/h=1000m/3600s为1/3.6m/s1m/min=0.001km/min
1.21.6km/h2.88km/h1/30*3.6km/h30m/s因为1m/s=3.6km/h2.s=3.8*10的八次方mv=3.0*10的八次方m/st=s/t=3.8*10的八次方m/3.0
1)=0.036km/h\x0d2)=5/18m/s\x0d
化单位.怎么搞的啊?1m/s=100cm/(1/60)min=6000cm/min.1km/h=1000m/60min=50/3m/min很基本的啊,小学都知道大化小乘以进率,小化大除以进率,都顺口溜
1(1)3m/s,18000cm/min(2)0.54km/h,900cm/min3.10/94.3125,1255.(L1+L2)/(v2-v1)(L1+L2)/(v1+v2)6.328
600厘米=6米70米=700分米5000米=5千米
2.5km=2500m=250000cm
200000m=2×10^2km,500000cm=5×10^3m,0.0035mm=3.5×10^(-6)m,0.005m=5×10^(-6)km,0.007μm=7×10^(-9)m,0.0005
2.5KM=2500m=250000CM一个一千倍.一个一百倍
3.6km=3600m=36000dm=360000cm3.2m=3200000um再问：那个第二个我输错是3.2MM=M=UM再答：3.2mm=0.0032m3.2mm=3200um
1000M
72Km/h=(20)m/s1m/s=(1)m/s340m/s=(1224)km/h30cm/min=(0.005)m/s请写出计算节果
0.36km/min=6m/s9km/h=2.5m/s7m/s=25.2km/h5.4km/h=1.5m/s81cm/s=0.81m/s
1km=1000m1m=100cm所以1km=100000cm附：‘km’全称Kilometer（公里,千米）厘米,长度单位符号为:cm.1厘米=1/100米也就是1m=100cm
12.5mm=1.25*(0.01)m=1.25*(0.00001)km
12m=(120)dm500cm=(50)dm4000m=(4)km1m=(100)cm1dm=(10)cm4cm5cm=(50)mm
6300km=6300000m=630000000cm=6300000000000um
“sunyellow”：您好.1cm=0.00001km1km=1000m1m=100cm1公里=1千米=1000米1米=100厘米1千米=100000厘米1厘米=0.00001千米我是个很土很土的土
18cm=(0.18)m=(0.00018)km
5.8km=(5800)m=(5)km(800)m
