How to convert Point to Light year
$$\text{Length}_{\text{ly}} = \text{Length}_{\text{pt}} \cdot 3.728864053364615663641707961378088e - 20$$
Examples
Example 1
Convert $25.0\ \text{pt}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 25.0 \cdot 3.728864053364615663641707961378088e - 20$$
$$\text{Length}_{\text{ly}} = 0.0000000000000000009322160133411539159104269903445219$$
$$\therefore \ 25.0\ \text{pt} = 0.0000000000000000009322160133411539159104269903445219 \ \text{ly}$$
Example 2
Convert $60.0\ \text{pt}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 60.0 \cdot 3.728864053364615663641707961378088e - 20$$
$$\text{Length}_{\text{ly}} = 0.000000000000000002237318432018769398185024776826853$$
$$\therefore \ 60.0\ \text{pt} = 0.000000000000000002237318432018769398185024776826853 \ \text{ly}$$
Example 3
Convert $120.0\ \text{pt}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 120.0 \cdot 3.728864053364615663641707961378088e - 20$$
$$\text{Length}_{\text{ly}} = 0.000000000000000004474636864037538796370049553653705$$
$$\therefore \ 120.0\ \text{pt} = 0.000000000000000004474636864037538796370049553653705 \ \text{ly}$$
Example 4
Convert $140.0\ \text{pt}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 140.0 \cdot 3.728864053364615663641707961378088e - 20$$
$$\text{Length}_{\text{ly}} = 0.000000000000000005220409674710461929098391145929323$$
$$\therefore \ 140.0\ \text{pt} = 0.000000000000000005220409674710461929098391145929323 \ \text{ly}$$
Example 5
Convert $160.0\ \text{pt}$ to $\text{ly}$.
$$\text{Length}_{\text{ly}} = 160.0 \cdot 3.728864053364615663641707961378088e - 20$$
$$\text{Length}_{\text{ly}} = 0.00000000000000000596618248538338506182673273820494$$
$$\therefore \ 160.0\ \text{pt} = 0.00000000000000000596618248538338506182673273820494 \ \text{ly}$$
