How many km in 120000000mm?

Answer 1

Just remember KHDMDCM

Km would be at the top. So go from mm (which is at the bottom) and count how many steps you have to do, so this one is 6. So since we moved to the left, we have to move the decimal point 6 to the left. So 120,000,000.00 would be changed to 120.000000. Do you see how we moved it? It went from the end and then moves 6.
