Water Footprint of Food Calculator
Example: 200g beef = 3,100 litres
Food requires water to grow, process, and transport. A single burger can require over 2,000 litres. This calculator uses data from the Water Footprint Network to estimate the water footprint of a meal and show which ingredients account for most of it.

How We Calculate This
Water footprint = sum of (grams × litres_per_kg / 1000) for each ingredient. Data from Water Footprint Network global averages: beef 15,500 L/kg, chicken 4,300 L/kg, cheese 5,000 L/kg, rice 2,500 L/kg, vegetables 300 L/kg, etc.

Frequently Asked Questions
Why does beef use so much water?
Beef cattle require years of feed (grain, grass) before slaughter, and each kg of feed requires water to grow. The water footprint includes all water used throughout the supply chain - about 15,500 litres per kg of beef.
What is a water footprint?
A water footprint measures the total freshwater used to produce something, including water for growing crops, raising animals, processing, and manufacturing. It's often called "virtual water" or "hidden water".
Where does this data come from?
Data is based on global averages from the Water Footprint Network, which has extensively studied water use in agriculture. Actual values vary by region, farming practices, and climate.
How can I reduce my water footprint?
The biggest impact comes from reducing meat (especially beef) and dairy consumption. Eating more vegetables, reducing food waste, and choosing locally-grown produce also helps reduce water usage.
