Convert Light year to Meter
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.
Meter
The meter (metre (UK)) is the SI unit of length. It is defined as the distance traveled by light in vacuum during a time interval of $\frac{1}{299\,792\,458}$ of a second.
How to convert Light year to Meter
$$\text{Length}_{\text{m}} = \text{Length}_{\text{ly}} \cdot 9460730472580800$$
Examples
Example 1
Convert $25.0\ \text{ly}$ to $\text{m}$.
$$\text{Length}_{\text{m}} = 25.0 \cdot 9460730472580800$$
$$\text{Length}_{\text{m}} = 236518261814520000$$
$$\therefore \ 25.0\ \text{ly} = 236518261814520000 \ \text{m}$$
Example 2
Convert $90.0\ \text{ly}$ to $\text{m}$.
$$\text{Length}_{\text{m}} = 90.0 \cdot 9460730472580800$$
$$\text{Length}_{\text{m}} = 851465742532272000$$
$$\therefore \ 90.0\ \text{ly} = 851465742532272000 \ \text{m}$$
Example 3
Convert $105.0\ \text{ly}$ to $\text{m}$.
$$\text{Length}_{\text{m}} = 105.0 \cdot 9460730472580800$$
$$\text{Length}_{\text{m}} = 993376699620984000$$
$$\therefore \ 105.0\ \text{ly} = 993376699620984000 \ \text{m}$$
Example 4
Convert $150.0\ \text{ly}$ to $\text{m}$.
$$\text{Length}_{\text{m}} = 150.0 \cdot 9460730472580800$$
$$\text{Length}_{\text{m}} = 1419109570887120000$$
$$\therefore \ 150.0\ \text{ly} = 1419109570887120000 \ \text{m}$$
Example 5
Convert $170.0\ \text{ly}$ to $\text{m}$.
$$\text{Length}_{\text{m}} = 170.0 \cdot 9460730472580800$$
$$\text{Length}_{\text{m}} = 1608324180338736000$$
$$\therefore \ 170.0\ \text{ly} = 1608324180338736000 \ \text{m}$$
