What food water footprint from 0.3 kg beef and the rest of the week? 15,030 L / week. Virtual water, not the tap.
Food water footprint
Type weekly masses and milk litres. 0.3 beef, 0.4 pork, 0.5 chicken, 0.3 rice, 3 L milk, 6 eggs and 0.7 bread give 15,030 L / week. Virtual water, not the meter.

How it works
Food water footprint in this calculator is virtual water per week. 0.3 kg beef, 0.4 pork, 0.5 chicken, 0.3 rice, 3 L milk, 6 eggs and 0.7 bread give 15,030 L / week. 0.5 / 0.2 / 0.3 / 0.2 / 2 / 4 / 0.5 give 14,140 L / week. 0.1 / 0.3 / 0.8 / 0.4 / 5 / 8 / 1 give 15,680 L / week.
Beef uses 15400 L/kg, pork 6000, chicken 4300, rice 2500, milk 1000 L/L, an egg 200 L, bread 1300 L/kg. The result is litres per week, not CO₂.
15,030 L / week is not a utility bill. 14,140 L / week is not a survey. 15,680 L / week is another basket. The calculator does not know the farm country.
Diet carbon footprint next door counts kg CO₂e/day from kcal. Waste and recycling count methane from kilograms. Here water stays: 0.3 kg beef in the first basket stays inside 15,030 L / week.
Type 0.3, 0.4, 0.5, 0.3, 3, 6 and 0.7, then Calculate. A comma in 0.3 parses. A seven-field sketch, not a supply-chain audit.
The first basket gives 15,030 L / week. The second gives 14,140 L / week. The third gives 15,680 L / week. More beef at the same rest raises 15,030.
Formula
L/week = beef×15400 + pork×6000 + chicken×4300 + rice×2500 + milk×1000 + eggs×200 + bread×1300.
How to use
- Type weekly beef 0.3 and pork 0.4.

Common questions
What water footprint from 0.3 kg beef and the rest of the week?
15,030 L / week. Virtual water, not a bill.
How much for the second basket?
14,140 L / week. 0.5 beef and less of the rest.
How much for the third basket?
15,680 L / week. More chicken, milk and eggs.
Is 15,030 L tap water?
No. Virtual water from masses and fixed L/kg. The home meter sits outside this calculator.
Is the result CO₂?
No. Litres per week. Diet CO₂e lives on the neighbour card.
Where does 15400 L/kg beef come from?
A constant in the code. You do not load it from a table on the page.
Do blank persons split 15,030?
No. Options stay empty. The result is the week sum, not per person.
Does a comma in 0.3 work?
Yes. 0,3 and 0.3 are the same mass.
Is this a supply-chain audit?
No. Seven typed fields. Farm country does not enter.
