Candle Wax CalculatorEditorial Policy
This page explains how the calculators and content on Candle Wax Calculator are checked for accuracy, how errors are handled, and what standards the writing follows. It is maintained by Ian Welkins, who also writes and verifies everything on the site.

How the calculators are verified
Every formula is hand-checked against manual calculations before it goes live, including edge cases: single-candle batches, very large batch counts, the fluid-ounce to milliliter conversion, the margin applied on top of the wax total, and fragrance oil calculated on the wax weight before the margin. The worked examples on each page are computed by hand and cross-checked independently, so a reader can confirm the math with the formulas shown next to each calculator.
The wax density figures are typical published values for candle pours, not exact measurements of any one supplier's wax. Every page states this plainly and advises a test pour before large batches, so the site never presents a typical value as a guaranteed one.
Estimates are labeled as estimates
Volume-to-weight conversion, batch scaling, and unit conversion are exact arithmetic and are presented as such. Fragrance loads and safety margins are choices the visitor makes — every page shows the values in use and lets the visitor adjust them. Wick sizing guidance is labeled as a starting point for testing, not a final answer. The site never presents a rule of thumb as an exact measurement.
Corrections
Mistakes are corrected, not hidden. When an error report checks out, the calculator or text is fixed and the correction is noted. Reporting an error is straightforward — see report an error for what to include.
Review cadence
The calculation logic and page content are re-checked on a regular schedule, and immediately whenever a correction is reported. The "Last reviewed" date at the top of this page shows when the checks described here were last completed.
What this site does not publish
No fabricated data, no invented statistics, and no testimonials. The content sticks to what can be checked: the formulas, the worked examples, and the assumptions behind each figure. If a figure cannot be verified, it is not printed. The site does not certify candle safety or replace supplier guidance on fragrance loads, curing, and testing.
Frequently asked questions
How do I report a calculation error?
Use the report an error page. Include the page URL, exactly what you entered, the result you got, and what you expected — that is usually enough to reproduce and fix the problem.
How often is the site reviewed?
The calculators are re-checked on a schedule, and every reported error is checked when it arrives. The “Last reviewed” date at the top of this page shows when those checks were last completed.
