## How to perform key conversions involving length measurements

The formulas for conversion are represented below:

### Centimeters to Astronomical Units Formula

UA = cm / 1,496x1013

Example: 30 Centimeters in Astronomical Units:

UA = cm / 1,496x1013

UA = 30 / 1,496x1013

UA = 2,0054x10-12

### Astronomical Units to Centimeters Formula

cm = UA * 1,496x1013

Example: 50 Astronomical Units in Centimeters:

cm = UA * 1,496x1013

cm = 50 * 1,496x1013

cm = 7,48x1014

## Frequently asked questions involving length and distance

### 100 Centimeters are equal to how many Astronomical Units

Considering that 1 Centimeter is equivalent to 6.684x10-14 Astronomical Units, you can use a rule of three to obtain that 100 Centimeters equals 6.684x10-12 Astronomical Units.

1 cm - 6,684x10-14 UA

100 cm - x

Apply the rule of three and get:

x cm = 100 x 6,684x10-14 UAcm

x = 6,684x10-12 UA

### 100 Astronomical Units equal how many Centimeters?

If for every 1 Astronomical Unit we have 1,496x1013 Centimeters, just multiply the amount of Astronomical Units (100) by 1,496x1013, so you will get that 100 AU equals 1.496x1015 cm. Observe the calculation below:

cm = UA * 1,496x1013

cm = 100 * 1,496x1013

cm = 1,496x1015
