Here's the pattern to metric prefixes:
#color(red)("K" color(white)(000)"H" color(white)(0000)"D" color(white)(0000)"M" color(white)(0000)"D" color(white)(0000)"C" color(white)(0000)"M")#
#color(blue)("Kilo, Heco, Deca, Meter, Deci, Centi, Mili")#
Lets start with Meter. Lets not worry about the units before it.
#color(red)("M" color(white)(0000)"D" color(white)(000000000)"C" color(white)(000000000)"M")#
#color(blue)("Meter, Decimeter, Centimeter, Milimeter")#
#color(green)("Meter")# is going to stay in the #color(orange)("ones")# digit.
#color(green)("Decimeter")# is going to be the #color(Orange)("tenths")# place.
#color(green)("Centimeter")# is going to be in the #color(orange)("hundredths")# place, and
#color(green)("Milimeter")# is going to b in the #color(orange)("thousandths")# place.
Since you want to change the 6 meters into centimeters, you will just change it to the #color(orange)("hundreths")# place. This will change the 6 meters to 600 centimeters.
