Last updated: October 23, 2026. This page explains how CupRuler creates, checks and updates its calculators and guides.
Our standards
- Primary sources first. Data comes from official statistics, standards bodies or the original publisher, and each page names its source and the period covered.
- Show the working. Each calculator states its formula and assumptions, with a worked example you can verify.
- Test before publishing. Our automated tests cover exact unit round-trips, fraction rounding to kitchen measures and every ingredient density used on the site. A failing test blocks publication.
- Independence. Advertisers and affiliate partners have no say in what we publish or how a result is calculated.
Methodology
Volume and weight conversions use exact definitions (1 US cup = 236.588 mL; 1 oz = 28.3495 g). Grams-per-cup figures come from the King Arthur Baking ingredient weight chart, which assumes flour is spooned and levelled. Fractions are rounded to the nearest kitchen measure.
Sources we use
- NIST Handbook 44 and SP 811 unit definitions (1 inch = 25.4 mm, 1 lb = 453.59237 g, 1 US cup = 236.5882365 mL)
- King Arthur Baking, Ingredient Weight Chart (grams per cup, spooned and levelled), credited on every ingredient page
How content is written
Pages are researched and edited by Alex. We use software, including AI writing tools, to help draft explanations and to generate pages from structured data (for example, one page per country or per loan amount). Every figure comes from the calculator engine or a cited data set, not from a language model, and generated text is reviewed against the source before publication. Pages that would add little beyond an existing page are excluded from search indexing.
How we verify a result
- Formula from a standard source. The formula is written out on the page.
- Data from the publisher. Figures come from the original dataset, never from memory or an AI model.
- Every ingredient density is a figure from the cited chart, not an estimate, and the test suite checks exact unit round-trips and fraction rounding to kitchen measures.
- Each converter shows a worked check, for example 100 g of all-purpose flour ÷ 120 g per cup = 0.833 cup.
- A failing test blocks publication. Nothing goes live until the whole test suite passes.
Review schedule
We review every page at least once every six months, and sooner when a source publishes a new edition. Each page shows its last-reviewed date, so you can always see how fresh it is.
| Data | Source | How often it is checked |
|---|---|---|
| Grams per cup for each ingredient | King Arthur Baking, Ingredient Weight Chart (spooned and levelled) | rechecked against the live chart at each review; retrieval date shown on the page |
| Exact unit definitions | NIST SP 811 and NIST Handbook 44 (1 US cup = 236.5882365 mL; 1 lb = 453.59237 g; 1 in = 25.4 mm) | fixed by definition; edition checked at each review |
What we do not claim
- No lab testing, hands-on product testing or panel of experts.
- No professional credentials for the editor.
- No ratings, reviews or testimonials from users.
