Answer 1

1.4 min= 1,4 *60s= 84s
52kg/m3= (52*1000g)/(0,001dm^3)=52 000 000 g/dm3
35000g/cm3=(35000 * 0,1dag)/(0,001)=3 500 000 dag/mm3
0,5kW=0,5 * 1000W=500W=500*0,01hW= 5 hW
13cm3=13*0,01m *0,01m*0,01m=0,000 013 m^3= 1,3 * 10^(-5) m^3
1,25min=1,25*60s= 75 s
32000hPa=32 000*1000 Pa= 32 MPa
80dm/s=(80*0,1*0,001 km)/(1/60min)= 0,48 km/min
0,02km/min=(0,02 * 1000m)/(1/60h)= 1200 m/h  
287,03cJ=287,03 * 0,01J=2,8703 J =0,0298703 hJ
