A vinegar dilution calculator uses the standard C1V1 = C2V2 formula to determine exactly how much concentrated vinegar and water you need to reach a target acidity. Whether you are diluting cleaning vinegar for household use, preparing pickling vinegar at the right strength, or safely working with glacial acetic acid, this tool gives you precise measurements instantly.

Common Vinegar Concentrations & Uses
| Type | Concentration | Common Uses |
|---|---|---|
| Mild Vinegar | 1 - 3% | Hair rinse, gentle cleaning, salad dressings |
| Table Vinegar | 4 - 7% | Cooking, pickling, canning, marinades |
| Cleaning Vinegar | 6 - 10% | Household cleaning, descaling, laundry |
| Horticultural | 10 - 20% | Weed killer, garden pest control |
| Industrial | 20 - 30% | Commercial cleaning, industrial processes |
| Glacial Acetic Acid | 99 - 100% | Laboratory use, chemical manufacturing |
How to Use the Vinegar Dilution Calculator
Diluting vinegar to the right concentration is important for food safety, effective cleaning, and safe handling. This free vinegar dilution calculator uses the standard C1V1 = C2V2 formula to tell you exactly how much concentrated vinegar and water to combine, eliminating guesswork and ensuring consistent results every time.
Step 1: Enter Your Starting Concentration
Select a preset or type in the acetic acid percentage of your vinegar. Standard white vinegar is 5%, cleaning vinegar is usually 6-10%, and industrial vinegar can be 20-30%. Check the bottle label for the exact acidity. If you are working with glacial acetic acid (99-100%), take appropriate safety precautions before handling.
Step 2: Set Your Target Concentration
Enter the acidity you want to achieve. For cooking and pickling, 5% is the standard. For a milder rinse or cleaning solution, 1-3% works well. The target must be lower than your starting concentration since you are diluting with water.
Step 3: Specify the Amount and Unit
Enter how much diluted vinegar you want to make and choose your preferred unit: cups, milliliters, fluid ounces, or liters. The calculator will determine the exact volumes of vinegar and water needed to produce that total amount at your target concentration.
Step 4: Review Your Results
Click Calculate Dilution to see clear mixing instructions. The results show the exact amount of vinegar to measure, the amount of water to add, the vinegar-to-water ratio, and the dilution factor. If your starting concentration is above 10%, a safety warning reminds you to wear protective equipment.
Understanding C1V1 = C2V2
The dilution formula C1 × V1 = C2 × V2 states that the amount of solute (acetic acid) stays constant when you add water. C1 is your starting concentration, V1 is the volume of concentrated vinegar you need, C2 is your target concentration, and V2 is the total final volume. Solving for V1 gives you V1 = (C2 × V2) / C1, and the water needed is simply V2 minus V1. This calculator handles all the math instantly in your browser.

FAQ
Is this vinegar dilution calculator free?
Yes, completely free with no limits, no account, and no signup. All calculations run locally in your browser using JavaScript. Nothing is stored or sent to any server.
Is my data safe and private?
Absolutely. Everything runs entirely in your browser. No data is transmitted to any server or shared with anyone. You can use the tool offline once the page has loaded.
What formula does this calculator use?
It uses the standard dilution equation C1 x V1 = C2 x V2, where C1 is your starting concentration, V1 is the volume of concentrated vinegar needed, C2 is your target concentration, and V2 is the total volume you want to make. The calculator solves for V1 and derives the water amount as V2 minus V1.
Can I dilute glacial acetic acid with this tool?
Yes, but exercise extreme caution. Glacial acetic acid (99-100%) is highly corrosive and can cause severe burns. Always wear chemical-resistant gloves and eye protection, work in a well-ventilated area, and add the acid to water, never water to acid. This calculator handles any starting concentration up to 100%.
What concentration of vinegar is safe for cooking?
Standard table vinegar for cooking is typically 4-7% acetic acid, with 5% being the most common in the US. For pickling and canning, the USDA recommends vinegar with at least 5% acidity to ensure food safety. Never use industrial-strength vinegar for food without proper dilution.
What is the difference between cleaning vinegar and regular vinegar?
Regular white vinegar sold for cooking is typically 5% acetic acid. Cleaning vinegar is usually 6-10% acetic acid, making it about 20-100% more acidic. Some industrial or horticultural vinegar products can be 20-30% acetic acid. Higher concentrations are more effective for cleaning but require careful handling.
Can I use this calculator for other acid dilutions?
The C1V1=C2V2 formula works for any simple dilution where you are mixing a concentrated solution with water. While this tool is designed for vinegar and acetic acid, the math applies equally to diluting citric acid solutions, hydrogen peroxide, or similar single-solute liquids.
