Personal Hygiene Calculators

What exactly will personal hygiene calculators calculate?

• Dilution of hygiene and disinfectants– based on the initial concentration (C1), target concentration (C2) and the desired final volume, the tool indicates how much concentrate and how much solvent should be measured. Perfect for preparing mouthwash, antibacterial agents or concentrates for cleaning the bathroom.
• Water consumption in the shower- based on the shower flow (l/min) and bathing time, the following are calculated: liters of water used, approximate cost of a single shower, annual consumption and approximate CO₂ emissions related to water heating.
• Hand washing effectiveness– you enter the time to rub your hands with soap, and the calculator shows whether you meet the recommended minimum of 20 seconds and what the estimated washing effectiveness is in percentage.
• Toothpaste stock planning- based on the weight of the tube, the dose of toothpaste per wash and the number of washes per day, the tool calculates how many days the packaging will last, when it will approximately run out and how many tubes you use per year.
• Joint control over the budget and ecology- thanks to clear numbers, you can easily calculate the impact your bathroom habits have on your water bills and the natural environment.

How to use calculators step by step?

1. At the top of the module, selectnumber precision– how many decimal places you want the results to have. Greater precision is useful when diluting solutions, less precision when estimating costs and days of using the paste.
2. In the section you are interested in (solution, shower, hand washing, paste), enter the data according to the field descriptions. You can change just one parameter and immediately observe the impact on the result.
3. In the handwashing module, click the"Check"button, and in the rest, use the"UPDATE ALL CALCULATIONS"button to calculate the entire set of calculators at once.
4. Read the results in the highlighted fields: see how many liters of water are lost in the shower, how many days a tube of toothpaste will last, what the dilution of the solution is and whether you wash your hands at a sufficiently high level of effectiveness.
5. Experiment: shorten the shower, change the dose of toothpaste or the concentration of the solution and check how quickly the annual values, costs and hygiene levels change - it's a great tool for practicing conscious habits.
