How to convert Yard to Light year
$$\text{Length}_{\text{ly}} = \text{Length}_{\text{yd}} \cdot 9.665215626321083800159307035892003e - 17$$
Examples
Example 1
Convert $20.0\ \text{yd}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 20.0 \cdot 9.665215626321083800159307035892003e - 17$$
$$\text{Length}_{\text{ly}} = 0.000000000000001933043125264216760031861407178401$$
$$\therefore \ 20.0\ \text{yd} = 0.000000000000001933043125264216760031861407178401 \ \text{ly}$$
Example 2
Convert $85.0\ \text{yd}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 85.0 \cdot 9.665215626321083800159307035892003e - 17$$
$$\text{Length}_{\text{ly}} = 0.000000000000008215433282372921230135410980508203$$
$$\therefore \ 85.0\ \text{yd} = 0.000000000000008215433282372921230135410980508203 \ \text{ly}$$
Example 3
Convert $120.0\ \text{yd}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 120.0 \cdot 9.665215626321083800159307035892003e - 17$$
$$\text{Length}_{\text{ly}} = 0.0000000000000115982587515853005601911684430704$$
$$\therefore \ 120.0\ \text{yd} = 0.0000000000000115982587515853005601911684430704 \ \text{ly}$$
Example 4
Convert $140.0\ \text{yd}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 140.0 \cdot 9.665215626321083800159307035892003e - 17$$
$$\text{Length}_{\text{ly}} = 0.0000000000000135313018768495173202230298502488$$
$$\therefore \ 140.0\ \text{yd} = 0.0000000000000135313018768495173202230298502488 \ \text{ly}$$
Example 5
Convert $200.0\ \text{yd}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 200.0 \cdot 9.665215626321083800159307035892003e - 17$$
$$\text{Length}_{\text{ly}} = 0.00000000000001933043125264216760031861407178401$$
$$\therefore \ 200.0\ \text{yd} = 0.00000000000001933043125264216760031861407178401 \ \text{ly}$$
