1. $a) 1,1A = 1100mA$

   $b) 1,75mA = 0,00175A$

   $c) 520kV = 520000V$

   $d) 54,2V = 54200mV$

   $1A=1000mA$

   $1mA=0,001$

   $1V=1000mV$

   $1mV=0,001V$

   $1kV=1000V$

   $1V=0,001kV$

2. `a)1,1A=1100mA`

   `b)1,75mA=0,00175A`

   `c)520kV=520000V`

   `d)54,2V=54200mV`

   Giải thích:

   `1A=1000mA`

   `1mA=0,001A`

   `1kV=1000V`

   `1V=1000mV.`
