On a standard ruler, 1.3 cm is slightly more than the 1 cm mark and just a little less than the 1.5 cm mark. It is typically located a third of the way between the 1 cm and 2 cm marks. If you closely observe the ruler, you'll see that it's just past the first full centimeter, indicating that it measures 3 millimeters beyond the 1 cm mark.
1m=100cm 0.13mX100cm=13cm Therefore, 0.13m is equal to 13cm.
