  • 4200cmkubik/menit=.....dmkubik/detik
    = (4200 : 1000) : 60
    = 0,07 dm3/detik
     
    18mkubik/menit=......m3/detik
    = 18 : 60
    = 0,3 m3/detik

    72km/jam=....m/detik
    = (72 x 1000) ; 3600
    = 20 km/jam

    16m/detik=....cm/detik
    = 16 x 100
    = 1600 cm/detik

    1200dam/jam.....km/jam
    =1200 : 100
    = 12 km/jam

    2,8hm/detik=......m/detik
    =2,8 x 10000
    = 28000 m/detik

    70m/detik=.......m/detik
    = 70 m/detik

    300dmkubik/menit=......cmkubik/menit
    = 300 x 1000
    = 300.000 cm3/menit

    36dmkubik/menit=.......mmkubik/menit
    = 36 x 1.000.000
    = 36.000.000 mm3/detik
