    \[m*10^3 =km\] so we use this conversion \[ \frac{km}{m*10^3}\] \[1.5*10^{11}m * \frac{km}{m*10^3}= \frac{1.5*10^{11} km}{10^3}= 1.5*10^8km\]

    I got 6.24*10^4nm and it seems wrong.

    you will need to multiply what you have by 10^9 in order to convert it to nano meters.

    That's why the -7 turns into 2 because -7 + 9 = 2
