Confused here... $F=mg=m \frac{GM}{r^2}$ We know 'g' is an acceleration which is $$ms^{-2}$$ Now to calculate 'g' we use $g=\frac{GM}{r^2}$ $$G=6.674 \times 10^{-11}$$ $$M=5.972 \times 10^{24}$$ $$r=6371$$ putting all this into that equation I get $$9.81 \times 10^6$$ Acceleration due to gravity is definitely not 9 million. Can anyone tell where I messed up? or what I'm not understanding.
