How the Hot 100 is formulated

Questions often arise about how the Hot 100 is tabulated. Here is the formula:

Sales are divided by 10

(so 100,000 downloads sold = 10,000 chart points)

Impressions are divided by 10,000

(so 100 million impressions = 10,000 chart points)

Streamings are divided by 500

(so 50,000 streams = 100 chart points)

In common terms, 100,000 downloads is equal to 100 million impressions.

I found this interesting. :P
