Question

How do you convert 410mm to meters? 410cm to meters? 410mm to cm?

Answer 1

.410
4.10
41.0

Use this as a guide: mm, cm, dc, m

Thats the order.  As you go from left to right (mm to m) you move the decimal to the left one place each time you move.  As you go from right to left (m to cm) you move the decimal to the right one place.
