Convert Astronomical unit to Kilometer
Unit definitions
Astronomical unit
An astronomical unit is the average distance from the center of the Earth to the center of the Sun.
Kilometer
A kilometer is $1\,000$ meters in length.
How to convert Astronomical unit to Kilometer
$$\text{Length}_{\text{km}} = \text{Length}_{\text{ua}} \cdot 149597870.7$$
Examples
Example 1
Convert $30.0\ \text{ua}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 30.0 \cdot 149597870.7$$
$$\text{Length}_{\text{km}} = 4487936121$$
$$\therefore \ 30.0\ \text{ua} = 4487936121 \ \text{km}$$
Example 2
Convert $85.0\ \text{ua}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 85.0 \cdot 149597870.7$$
$$\text{Length}_{\text{km}} = 12715819009.5$$
$$\therefore \ 85.0\ \text{ua} = 12715819009.5 \ \text{km}$$
Example 3
Convert $100.0\ \text{ua}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 100.0 \cdot 149597870.7$$
$$\text{Length}_{\text{km}} = 14959787070$$
$$\therefore \ 100.0\ \text{ua} = 14959787070 \ \text{km}$$
Example 4
Convert $145.0\ \text{ua}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 145.0 \cdot 149597870.7$$
$$\text{Length}_{\text{km}} = 21691691251.5$$
$$\therefore \ 145.0\ \text{ua} = 21691691251.5 \ \text{km}$$
Example 5
Convert $180.0\ \text{ua}$ to $\text{km}$.
$$\text{Length}_{\text{km}} = 180.0 \cdot 149597870.7$$
$$\text{Length}_{\text{km}} = 26927616726$$
$$\therefore \ 180.0\ \text{ua} = 26927616726 \ \text{km}$$
