Convert these measurements. 39 cm to m

Hint: To convert the given dimensions into meters, we will use the scale \[1{\text{ cm}} = \dfrac{1}{{100}}{\text{ m}}\] and we will convert the given measurement 39 cm to find the required value.

Complete step by step answer:

We are given that the measurement is 39 cm.
We know that the scale is \[1{\text{ m}} = 100{\text{ cm}}\].
Rewriting the given scale for 1 cm, we get
\[ \Rightarrow 1{\text{ cm}} = \dfrac{1}{{100}}{\text{ m}}\]
First, we will convert the given measurement 39 cm by using the above scale.
\[
   \Rightarrow 39 \times \dfrac{1}{{100}}{\text{ m}} \\
   \Rightarrow \dfrac{{39}}{{100}}{\text{ m}} \\
   \Rightarrow 0.39{\text{ m}} \\
 \]
Hence, the required value is \[0.39\] m.

Note: We divide the measurements in cm by 100 to find the required value in meters. Students multiply the measurements by 100 instead of divide, which is wrong. You should be familiar with the conversion of all the units in meters. If it is not given in the question that in which unit we have to convert, then we will convert the given value in meters. Avoid calculation mistakes.
