How to convert Centimeter to Millimeter
$$\text{Length}_{\text{mm}} = \text{Length}_{\text{cm}} \cdot {10}^{1}$$
Examples
Example 1
Convert $40.0\ \text{cm}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 40.0 \cdot {10}^{1}$$
$$\text{Length}_{\text{mm}} = 400$$
$$\therefore \ 40.0\ \text{cm} = 400 \ \text{mm}$$
Example 2
Convert $75.0\ \text{cm}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 75.0 \cdot {10}^{1}$$
$$\text{Length}_{\text{mm}} = 750$$
$$\therefore \ 75.0\ \text{cm} = 750 \ \text{mm}$$
Example 3
Convert $115.0\ \text{cm}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 115.0 \cdot {10}^{1}$$
$$\text{Length}_{\text{mm}} = 1150$$
$$\therefore \ 115.0\ \text{cm} = 1150 \ \text{mm}$$
Example 4
Convert $135.0\ \text{cm}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 135.0 \cdot {10}^{1}$$
$$\text{Length}_{\text{mm}} = 1350$$
$$\therefore \ 135.0\ \text{cm} = 1350 \ \text{mm}$$
Example 5
Convert $200.0\ \text{cm}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 200.0 \cdot {10}^{1}$$
$$\text{Length}_{\text{mm}} = 2000$$
$$\therefore \ 200.0\ \text{cm} = 2000 \ \text{mm}$$
