Reptile [31]

1.54 x 10⁶kW

Explanation:

The problem here is converting from megawatts into kilowatts.

Given 1540megawatts.

The mega- and kilo- watts are prefixes that denotes multiples of units.

1 megawatt = 10⁶watts

1 kilowatt = 10³watts

Now given 1540megawatts power to Kilowatt power;

We see that :

1000kW = 1mW

1540mW x $\frac{1000kW}{1mW}$ = 1.54 x 10⁶kW
