## Step-by-Step Guide for Converting cm to m

- Understand the conversion factor. The basic unit of length in the metric system is the meter. One meter is defined as 100 centimeters. Thus, the conversion factor between centimeters and meters is 100.
- Write down the length conversion formula:
**Length in meters (m) = Length in centimeters (cm) ÷ 100** - Apply the formula:
To convert

**3 cm**to meters, divide 3 by 100.**0.03 m = 3 cm ÷ 100**
