servings
How to estimate it
Fermi’s official “Napkin math”
Start with the world's 8 billion people. Coke is everywhere, but not everyone drinks one on a given day. Say 1 in 4 people has a serving.
- World population
- 8,000,000,000
- Have a Coke today
- ~1 in 4
- 8B ÷ 4
- ≈ 2 billion
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Countries and territories Coca-Cola sells in
- 200+
- Company reported servings per day
- ~1.9 billion
- Equivalent to per second
- ~22,000
Reference cited by Fermi: The Coca-Cola Company FAQ: "more than 1.9 billion servings of our drinks are enjoyed in more than 200 countries each day"
