Editorial policy

What we publish

• Calculators. Deterministic tools for construction and earthwork quantities. A calculator is a formula and a set of inputs; it ships with its formula shown, its assumptions and limitations stated, and a version and a review date. The rules are on how we calculate.
• Guides. Pages that explain a method or a distinction the calculators depend on, such as bank versus loose volume or why truck capacity has two limits. A guide cites primary sources for any external figure it uses.
• Buyer’s guides. Pages about third-party software. Every statement about a product is read from that vendor’s own site and dated. The rules are on how we review software.

How a page earns its place

Nothing is published because it is easy to publish. Each calculator and each guide has a research record: the search term it answers, the demand band exactly as the keyword tool reported it (a range, never converted into a made-up figure), and what the search results for that term actually look like. Pages that would answer the same question are merged into one rather than published side by side, and a term whose demand has not been measured is labelled unvalidated, not dressed up.

The search results themselves are checked on Google in the United States, because that is the market and the engine the site is written for. When a check turns out to have read a result wrongly, the page is corrected. On 29 September 2026 a guide on cubic yards to tons was replaced by a calculator, and its address now redirects there, after Google’s results for that search proved to be calculators rather than articles.

What we do not publish

• Prices, market averages or a “typical cost”. Every price in a calculator result is one the reader typed. The only prices on the site are a software vendor’s own published prices, quoted with the date they were read.
• Material densities, swell factors or bag yields that we cannot source. Where a manufacturer or a standard publishes a figure for a defined product, or an agency publishes a factor for a stated material and condition, it is used exactly as published, recorded and dated on the calculator that uses it, labelled as what it is, and offered as a choice rather than applied for the reader; an agency factor is never presented as a material density. A figure quoted only in a note or a warning never changes a result. A figure we have read but cannot place is recorded as a candidate and not offered.
• Ratings, scores, stars, rankings or “best” badges for software.
• Reviews, testimonials or results that did not happen. We do not say we tested a product we have not used.
• Engineering, safety or financial advice.

Advertising, and who pays for what

The site is paid for by advertising. The calculators are free, there is no account and there is no paid tier. Ads sit in fixed positions below a finished calculator and between sections of supporting content; they never appear inside the controls or between an input and its result.

No advertiser and no software vendor influences what a page says. No vendor has paid for inclusion, placement or wording on a buyer’s guide, and there are no affiliate links on the site.

The owner’s commercial interest

Calcumetryx has a commercial interest in construction estimating software beyond this website. No vendor on this page has paid for inclusion, placement or wording, no link here is an affiliate link, and no product connected to this site’s owners is listed, recommended or compared on this page.

If a product connected to this site’s owners were ever included in a comparison, it would be labelled as such, held to the same evidence rules as every other product, and not placed first by default. If a page could not meet those conditions, the product would be left off the page rather than the page being softened around it.

How the content is produced

The text and the code of this site are drafted with the help of an AI assistant, working under the direction of the person who publishes it (see who makes this site). We say so because it is true and because a reader deciding how much to rely on a page is entitled to know. The process, in order: research and drafting with AI assistance; checking each source and each statement about a product against the primary source; automated tests on every calculation; and publication under the publisher’s responsibility. We do not describe any page as human-reviewed, or as reviewed by an expert, unless a record says who reviewed it and when.

What stands behind the drafting: calculators are covered by automated tests whose expected values are worked out by hand from first principles, not by running the code and recording what it said; statements about a software product are checked against that vendor’s own site; and every external figure carries a source record. No page on this site has been reviewed by a licensed engineer or estimator, and none claims to have been.

Keeping pages current

• Each calculator shows a formula version and a last-reviewed date. If the way something is computed changes, the version changes.
• Guides show the date they were last updated.
• A buyer’s guide carries two dates: when it was last edited, and when its claims about the vendors were last read on the vendors’ own sites. The second is the date of the actual check; an edit to the prose does not move it forward.

Errors are handled under the corrections policy.

The rest of how this site works

• Sources and data — Which sources a number may come from, which it may not, and how every external figure on the site is recorded and dated.
• How we review software — The evidence levels, the three states of a claim, and the rules for prices and rankings on buyer’s guides. No scores, no stars.
• Corrections policy — How to report an error in a calculation, a guide or a statement about a product, what we do about it, and the public log of changes.
• Who makes this site — Who publishes Calcumetryx, how AI assistance is used in drafting, and what credentials are and are not claimed.
