Convert Light year to Astronomical unit
Unit definitions
Light year
A light year is equal to the distance light travels in a Julian year ($365.25$ days). It is exactly $9\,460\,730\,472\,580\,800$ meters.
Astronomical unit
An astronomical unit is the average distance from the center of the Earth to the center of the Sun.
How to convert Light year to Astronomical unit
$$\text{Length}_{\text{ua}} = \text{Length}_{\text{ly}} \cdot 63241.07708426628026865358318231731$$
Examples
Example 1
Convert $25.0\ \text{ly}$ to $\text{ua}$.
$$\text{Length}_{\text{ua}} = 25.0 \cdot 63241.07708426628026865358318231731$$
$$\text{Length}_{\text{ua}} = 1581026.927107$$
$$\therefore \ 25.0\ \text{ly} = 1581026.927107 \ \text{ua}$$
Example 2
Convert $65.0\ \text{ly}$ to $\text{ua}$.
$$\text{Length}_{\text{ua}} = 65.0 \cdot 63241.07708426628026865358318231731$$
$$\text{Length}_{\text{ua}} = 4110670.010477$$
$$\therefore \ 65.0\ \text{ly} = 4110670.010477 \ \text{ua}$$
Example 3
Convert $115.0\ \text{ly}$ to $\text{ua}$.
$$\text{Length}_{\text{ua}} = 115.0 \cdot 63241.07708426628026865358318231731$$
$$\text{Length}_{\text{ua}} = 7272723.864691$$
$$\therefore \ 115.0\ \text{ly} = 7272723.864691 \ \text{ua}$$
Example 4
Convert $145.0\ \text{ly}$ to $\text{ua}$.
$$\text{Length}_{\text{ua}} = 145.0 \cdot 63241.07708426628026865358318231731$$
$$\text{Length}_{\text{ua}} = 9169956.177219$$
$$\therefore \ 145.0\ \text{ly} = 9169956.177219 \ \text{ua}$$
Example 5
Convert $185.0\ \text{ly}$ to $\text{ua}$.
$$\text{Length}_{\text{ua}} = 185.0 \cdot 63241.07708426628026865358318231731$$
$$\text{Length}_{\text{ua}} = 11699599.260589$$
$$\therefore \ 185.0\ \text{ly} = 11699599.260589 \ \text{ua}$$
