12 cm converted to m

Answer 1

Since there are 100 cm in 1 m, you must divide 12 by 100. This gives you 12/100, which can be reduced to 3/25, or 0.12 in decimal form. Whenever you are converting in metric units, you only have to move the decimal based on the different measurements. In this case, a meter is 100 centimeters, so the decimal is moved two places over. Which direction you move it depends on which way you are converting. Converting from a smaller size to a bigger one requires you to move the decimal to the left, and converting from a larger size to a smaller one requires you to move the decimal to the right, adding zeroes as necessary.
