How to convert Light year to Millimeter
$$\text{Length}_{\text{mm}} = \text{Length}_{\text{ly}} \cdot 9460730472580800000$$
Examples
Example 1
Convert $25.0\ \text{ly}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 25.0 \cdot 9460730472580800000$$
$$\text{Length}_{\text{mm}} = 236518261814520000000$$
$$\therefore \ 25.0\ \text{ly} = 236518261814520000000 \ \text{mm}$$
Example 2
Convert $75.0\ \text{ly}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 75.0 \cdot 9460730472580800000$$
$$\text{Length}_{\text{mm}} = 709554785443560000000$$
$$\therefore \ 75.0\ \text{ly} = 709554785443560000000 \ \text{mm}$$
Example 3
Convert $100.0\ \text{ly}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 100.0 \cdot 9460730472580800000$$
$$\text{Length}_{\text{mm}} = 946073047258080000000$$
$$\therefore \ 100.0\ \text{ly} = 946073047258080000000 \ \text{mm}$$
Example 4
Convert $130.0\ \text{ly}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 130.0 \cdot 9460730472580800000$$
$$\text{Length}_{\text{mm}} = 1229894961435504000000$$
$$\therefore \ 130.0\ \text{ly} = 1229894961435504000000 \ \text{mm}$$
Example 5
Convert $165.0\ \text{ly}$ to $\text{mm}$.
$$\text{Length}_{\text{mm}} = 165.0 \cdot 9460730472580800000$$
$$\text{Length}_{\text{mm}} = 1561020527975832000000$$
$$\therefore \ 165.0\ \text{ly} = 1561020527975832000000 \ \text{mm}$$
