How to Convert square millimeter to square kilometer
1 square millimeter [mm^2] = 1.E-12 square kilometer [km^2]
1 square kilometer [km^2] = 1000000000000 square millimeter [mm^2]
we use cross multiplication method
square millimeter [mm^2] → square kilometer [km^2]
1 → 1.E-12
1.5 → ?( suppose x)
=>1.5*1.E-12=1*x
by simplifying
x=1.5E-12
