What is Degrees of Separation?

The concept of "six degrees of separation" suggests that any two people on Earth are connected through a chain of no more than six acquaintances. This idea was popularized by the play "The Six Degrees of Kevin Bacon" and later studied in social network theory.

On Facebook, degrees of separation refers to the number of steps needed to connect two users through mutual friends. Each step represents one level of connection in the social graph.

How to Use This Calculator

1. Enter the number of friends the starting person has
2. Enter the number of friends the target person has
3. Select the degree of separation you want to calculate (1-6)
4. Click "Calculate" to see the estimated number of connections

The calculator uses the average number of friends to estimate the potential connections between two people at a given degree of separation.

How the Degrees of Separation Calculation Works

The calculation is based on the average number of friends each person has. The formula used is:

For example, if the average number of friends is 200 and you're calculating for degree 3, the calculation would be:

This means there are potentially 8 million paths of degree 3 connections between two people with an average of 200 friends each.

Real-World Examples

Let's look at some real-world scenarios to understand how degrees of separation works:

Example 1: Close Friends

If you have 100 friends and your friend has 150 friends, the number of degree 2 connections would be:

This means there are potentially 15,000 paths of degree 2 connections between you and your friend.

Example 2: Strangers

If you have 50 friends and the target person has 30 friends, the number of degree 3 connections would be:

This shows the potential connections grow exponentially with each additional degree of separation.
