How to convert Light year to Kilometer
$$\text{Length}_{\text{km}} = \text{Length}_{\text{ly}} \cdot 9460730472580.8$$
Examples
Example 1
Convert $40.0\ \text{ly}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 40.0 \cdot 9460730472580.8$$
$$\text{Length}_{\text{km}} = 378429218903232$$
$$\therefore \ 40.0\ \text{ly} = 378429218903232 \ \text{km}$$
Example 2
Convert $85.0\ \text{ly}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 85.0 \cdot 9460730472580.8$$
$$\text{Length}_{\text{km}} = 804162090169368$$
$$\therefore \ 85.0\ \text{ly} = 804162090169368 \ \text{km}$$
Example 3
Convert $105.0\ \text{ly}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 105.0 \cdot 9460730472580.8$$
$$\text{Length}_{\text{km}} = 993376699620984$$
$$\therefore \ 105.0\ \text{ly} = 993376699620984 \ \text{km}$$
Example 4
Convert $145.0\ \text{ly}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 145.0 \cdot 9460730472580.8$$
$$\text{Length}_{\text{km}} = 1371805918524216$$
$$\therefore \ 145.0\ \text{ly} = 1371805918524216 \ \text{km}$$
Example 5
Convert $190.0\ \text{ly}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 190.0 \cdot 9460730472580.8$$
$$\text{Length}_{\text{km}} = 1797538789790352$$
$$\therefore \ 190.0\ \text{ly} = 1797538789790352 \ \text{km}$$
