Astronomical unit [ua]

Unit definitions

$\frac{1}{10^{3}}$ of a meter is a millimeter.

An astronomical unit is the average distance from the center of the Earth to the center of the Sun.

$$\text{Length}_{\text{ua}} = \frac{\text{Length}_{\text{mm}}}{149597870700000}$$

Convert $20.0\ \text{mm}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = \frac{20.0}{149597870700000}$$

$$\text{Length}_{\text{ua}} = 0.0000000000001336917424453689099199190674042127$$

$$\therefore \ 20.0\ \text{mm} = 0.0000000000001336917424453689099199190674042127 \ \text{ua}$$

Convert $70.0\ \text{mm}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = \frac{70.0}{149597870700000}$$

$$\text{Length}_{\text{ua}} = 0.0000000000004679210985587911847197167359147445$$

$$\therefore \ 70.0\ \text{mm} = 0.0000000000004679210985587911847197167359147445 \ \text{ua}$$

Convert $105.0\ \text{mm}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = \frac{105.0}{149597870700000}$$

$$\text{Length}_{\text{ua}} = 0.0000000000007018816478381867770795751038721168$$

$$\therefore \ 105.0\ \text{mm} = 0.0000000000007018816478381867770795751038721168 \ \text{ua}$$

Convert $145.0\ \text{mm}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = \frac{145.0}{149597870700000}$$

$$\text{Length}_{\text{ua}} = 0.0000000000009692651327289245969194132386805423$$

$$\therefore \ 145.0\ \text{mm} = 0.0000000000009692651327289245969194132386805423 \ \text{ua}$$

Convert $185.0\ \text{mm}$ to $\text{ua}$.

$$\text{Length}_{\text{ua}} = \frac{185.0}{149597870700000}$$

$$\text{Length}_{\text{ua}} = 0.000000000001236648617619662416759251373488968$$

$$\therefore \ 185.0\ \text{mm} = 0.000000000001236648617619662416759251373488968 \ \text{ua}$$
