How to Use This Calculator

Enter the surface area to be dyed in square inches or square feet.
Select the dye type (alcohol-based, water-based, oil-based) for coverage rate.
Input the number of coats planned and dye coverage rate from the product label.
Review the total dye volume needed in milliliters or ounces.
Test dye on a scrap piece first to verify color and absorption before applying to your project.

How the result changes with Coverage Rate

Coverage Rate	Total Dye Needed	Total Dye Needed
1.45	6.9 oz	204 mL
3.82	2.62 oz	77.4 mL
6.67	1.5 oz	44.3 mL
9.05	1.1 oz	32.7 mL

What each input means

Surface Area: Total leather surface area to dye in square feet
Number of Coats: Number of dye coats (2-3 coats recommended for even color)
Coverage Rate: Dye coverage per ounce (check manufacturer specs, ~3 sq ft/oz typical)
Application Method: 1 = Dauber/wool (0.8x efficiency), 2 = Spray (1.2x), 3 = Immersion (2.0x usage)
