## Redshift Distance Formula

The following formula is used to calculate the Redshift Distance.

**RD = v / H**

- Where RD is the Redshift Distance (Mpc)
- v is the velocity (km/s)
- H is the Hubble Constant (km/s/Mpc)

## How to Calculate Redshift Distance?

The following example problems outline how to calculate Redshift Distance.

Example Problem #1:

- First, determine the velocity (km/s).
- The velocity (km/s) is given as: 150.

- Next, determine the Hubble Constant (km/s/Mpc).
- The Hubble Constant (km/s/Mpc) is provided as: 74.

- Finally, calculate the Redshift Distance using the equation above:

RD = v / H

The values given above are inserted into the equation below and the solution is calculated:

RD = 150 / 74 = 2.02 (Mpc)

Example Problem #2:** **

For this problem, the variables needed are provided below:

velocity (km/s) = 200

Hubble Constant (km/s/Mpc) = 69.8

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
