Dye Bath Ratio Calculator

Summary

Enter fabric weight and liquor ratio to instantly calculate the water volume needed for your dye bath.

How it works

1. Enter the total weight of your dry fabric in kilograms or pounds.
2. Set the target liquor ratio — the number of water parts per part of fabric (e.g. 20 for a 1:20 ratio).
3. The calculator multiplies fabric weight by the ratio to get total water volume.
4. Results are shown in liters and converted to US gallons for reference.
5. Adjust inputs to compare different ratios side by side.

Use cases

• Calculate water volume for hand-dyeing yarn or fabric.
• Scale up dye bath water when dyeing large fabric cuts in a drum or vat.
• Verify the liquor ratio for a dye recipe before mixing.
• Convert between kilograms and pounds when following international dye recipes.
• Determine how much dye powder to dissolve for a specific bath concentration.
• Plan water usage and dye chemical quantities for production runs.
