What it helps you decide
Convert common vessel capacity or a water test into wax fill weight.
Candle production
Start with a common jar or tin capacity, account for headspace and blend density, then calculate wax and fragrance for one vessel or a production run.
The values already filled in are a working example—not a recommendation.
Your numbers
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Important limit
Confirm the exact vessel lot with a water-weight test, use the wax supplier density if available, leave a tested fill and wick clearance, and complete full burn testing. Presets are nominal planning capacities and can change by supplier or model revision.
About this free craft materials & fabrication tool
Convert common vessel capacity or a water test into wax fill weight. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
Convert common vessel capacity or a water test into wax fill weight.
Measure the real mold, vessel, fabric, or batch; then use the exact supplier ratio, density, usage ceiling, cure instructions, and expected waste.
Key inputs: Vessel planning preset; Measured water capacity to fill line; Capacity source; Headspace / fill reduction; Wax blend density.
Use the estimate to prepare a controlled test quantity. Confirm fit, cure, burn, color, strength, or cut yield before committing a full production run.
Excel spreadsheet export
Use the Wax & Vessel Pour Volume Calculator in your browser, then export a branded .xlsx materials worksheet to save material measurements, supplier assumptions, and the quantity planned for the project.
This gives you a portable materials worksheet you can save with an order, production record, planning meeting, or pricing review. The workbook keeps the source link and date with the numbers, making it easier to understand where the result came from when you reopen or share it later.
Spreadsheet questions
Use the browser calculator for speed, then take the result into the spreadsheet workflow that fits your business.
Yes. Enter your information, review the live result, and select Export to Excel. Batch Scale creates a branded .xlsx workbook with your inputs and the result shown by the tool.
The workbook includes a Tool Result sheet, an Inputs sheet, the original calculator link, and the date generated. When a supported calculator has an Excel formula profile, its result cells remain connected to the editable input cells.
You can import the .xlsx workbook into Google Sheets. Because spreadsheet applications sometimes interpret formulas and formatting differently, confirm any important result after importing—especially before using it for pricing, safety, compliance, or production.
Yes. The calculator and workbook are free. The first Excel export on a device asks for your email and permission to receive occasional practical Batch Scale resources. Once captured, later tool exports on that device download directly.
Complete workflow guide
A calculator can check the math. A reliable product also needs clear supplier information, a repeatable process, testing in the final package, and the right label for what the product is and what you claim it does.
Learn the workflow
Evaluate glass dimensions, wall thickness, finish, color, supplier, and performance when a candle vessel or lot changes.
