1V=......mV 1V=......kV 1kV=.....mV 1mV=......1kV (ghi ra giúp em cả cách tính nữa ạ)

`Đáp` `án:`

`1V=1000mV`

`1V=1/1000=0,001KV`

`1kV=1.000.000 mV`

`1mV=`$\dfrac{1}{1.000.000}$ `=0,000001``KV`

 _ _ _ _ __ _ _ _ _ _ _ _ _ _ _ _ _

$\text{Ta có quy luật sau : }$

`1V=1000mV`

`1KV=1000V=1.000.000 mV`

`Vd:`

`_` `5V=5.1000= 5000mV`

`_``7V=``7.`$\dfrac{1}{1000}$ `=  0,007    KV  `

`_``6mV=6.`$\dfrac{1}{1.000.000}$ `=0,000006``KV`
