Dilution Ratio Calculator
The Dilution Ratio Calculator determines how much concentrate and water (or solvent) to mix for a desired dilution. Enter a ratio like 1:10 and total volume to get exact measurements — ideal for cleaning products, chemicals, fertilizers, and lab solutions.

What is a Dilution Ratio?
A dilution ratio specifies how much concentrate to mix with a diluent (usually water). A 1:10 dilution ratio means 1 part concentrate to 10 parts water, creating 11 total parts. In chemistry, dilution follows the formula C₁V₁ = C₂V₂ to maintain the same amount of solute.
Dilution ratios are critical in cleaning (1:32 for floor cleaner), agriculture (1:100 for pesticide spray), medical labs (serial dilutions for blood tests), photography (1:4 for developer solutions), and food service (concentrated syrups and juices).
Fórmulas e Equações Utilizadas
Esta Dilution Ratio Calculator usa 5 equações principais:
1 Concentrate Amount ▼
For 1:10 dilution of 1 liter total: Concentrate = 1000ml / (10+1) = 90.9 ml.
2 Water Amount ▼
For 1 liter at 1:10: Water = 1000 - 90.9 = 909.1 ml.
3 Serial Dilution ▼
Starting at 1M with three 1:10 dilutions: Final = 1 × (1/10)³ = 0.001 M.

Perguntas Frequentes
What does a 1:10 dilution ratio mean? ▼
A 1:10 ratio means 1 part concentrate mixed with 10 parts water, giving 11 total parts. To make 1 liter: use 90.9 ml concentrate and 909.1 ml water.
How do I convert dilution ratio to percentage? ▼
Divide 1 by the total parts and multiply by 100. A 1:20 dilution = 1/21 × 100 = 4.76% concentrate. A 1:4 dilution = 1/5 × 100 = 20% concentrate.
What is the difference between 1:10 and 1/10 dilution? ▼
In many contexts, 1:10 means 1 part to 10 parts (11 total). But in scientific notation, a 1/10 dilution means 1 part in 10 total parts. Always clarify whether the ratio is part:part or part:total.
How do I dilute concentrated bleach for disinfecting? ▼
The CDC recommends 1:48 (1 tablespoon per quart) for general disinfection with regular 5.25% bleach. For heavy contamination, use 1:10. Always check the bleach concentration label.
What is a serial dilution? ▼
A serial dilution performs multiple dilution steps sequentially. Each step dilutes by the same factor. Three 1:10 dilutions create a total 1:1000 dilution. This technique is used in microbiology to count bacteria and in medicine for antibody titers.
