How to estimate it

Fermi’s official “Napkin math”

Start with everyone on Earth, about 8 billion people. How much garlic does one person get through? Plenty eat none, but kitchens across Asia use loads. Call it a bulb a week, and a bulb is about 50 grams.

World population
8,000,000,000
A bulb a week, 50 g × 52
≈ 2.6 kg each
8B × 2.6 kg
≈ 21,000,000 t

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference
World garlic harvest, 2024 (FAOSTAT)
29,690,764 t
Of which China
≈ 21.6M t (73%)
Rounded
≈ 29,700,000
