Intensity table for common goods.
Total water = quantity × intensity. Beef / chocolate / coffee are liters per kg; cotton shirt is liters per shirt.
Embedded water ≈ 7,708 L
Human-readable impact: that is roughly 385.4 20-liter drinking-water cans worth of virtual water—most of it rainfed or upstream in the supply chain, not poured from your tap.
Virtual Water Footprint Calculator helps you intensity table for common goods. It is commonly used by engineers, lab users, field operators for virtual water, water footprint food, cotton shirt water.
Constants (liters)
- Beef **15,415 / kg**
- Chocolate **17,285 / kg**
- Coffee **18,900 / kg**
- Cotton shirt **2,500 each**
Figures are order-of-magnitude supply-chain “virtual” water from common footprint literature, not a single farm audit.
