Metric Epoxy Calculator
This metric epoxy calculator is for projects measured in centimeters and liters. It keeps metric entry first while still showing gallon equivalents for users comparing products sold in different unit systems.

Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Why this page exists
- Designed for users measuring length, width, diameter, and depth in centimeters.
- Outputs liter-based planning while preserving gallon equivalents for kit comparison.
- Works for rectangular and circular shapes.
- Pairs naturally with the unit converter for mixed supplier listings.
How to measure or set the inputs
- Switch the unit system to metric before entering measurements.
- Enter centimeters for dimensions and keep depth in the same measurement system.
- Use the liter result as the main planning number, then compare any gallon-based kit listing with the converter.
- Move to the deep-pour page if the metric depth is large enough to require staged lifts.
Common mistakes that cost money
- Entering millimeters into centimeter fields without converting.
- Mixing inch depth with centimeter length and width.
- Comparing a liter result against a gallon kit without conversion.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
Can I enter millimeters?
Convert millimeters to centimeters first. For example, 12 mm is 1.2 cm.
Why does the page still mention gallons?
Many epoxy kits are sold in gallons even when the project is measured in metric, so both units help with buying.
Is this different from the main calculator?
The core math is the same, but this page is structured for metric search intent and metric buying questions.
How accurate is this epoxy calculator?
It is designed for planning and procurement, not for replacing the manufacturer data sheet. The calculator is most useful when you add the right waste buffer and choose the page that matches your project type.
Why does the recommended amount exceed the raw volume?
Real projects lose material to mixing cups, edge soak-in, seepage, and safety margin. Raw volume alone is often too optimistic.
Should I still check the resin brand instructions?
Yes. Always confirm maximum pour depth, cure conditions, and mix ratio with the product documentation you plan to buy.
