Crushed Concrete Calculator aims to provide clear, accurate, and useful concrete calculators, estimators, conversions, and supporting technical content.
Even with careful research and testing, errors can happen. When a genuine issue is identified, we want it reported, reviewed, and corrected.
What Can Be Reported
You can report issues involving:
- Calculator errors
- Incorrect formulas
- Incorrect unit conversions
- Wrong rounding behavior
- Outdated manufacturer values
- Broken or outdated sources
- Incorrect technical statements
- Missing limitations
- Confusing instructions
- Display or usability problems
- Typographical errors that affect meaning
How to Report an Issue
Send correction reports to:
To help us investigate efficiently, please include as much relevant information as possible.
Useful details include:
- Page or calculator name
- Page URL
- Values you entered
- Result you received
- Result you expected
- Source or reference supporting the correction
- Screenshot, if useful
- Description of the issue
“Calculator wrong” is technically feedback, but unfortunately not enough evidence to interrogate the mathematics.
How We Review Corrections
When a correction is reported, we may review:
- The calculator formula
- Source data
- Unit conversions
- Rounding logic
- Input validation
- Manufacturer specifications
- Supporting content
- Published examples
- Relevant external references
The purpose is to determine whether the reported issue is a genuine error, a misunderstanding of the tool, or a difference caused by assumptions or product-specific information.
Calculation Errors
If a calculator contains an actual mathematical or programming error, we aim to correct it as soon as reasonably practical.
Depending on the issue, the correction may involve:
- Updating calculation logic
- Correcting a formula
- Fixing a unit conversion
- Adjusting rounding
- Updating default values
- Improving validation
- Clarifying instructions
Source Corrections
External information can change over time.
Manufacturers may update:
- Product yields
- Packaging
- Technical documentation
- Application guidance
- Product specifications
Other technical sources may also be revised or relocated.
If an important source is outdated or broken, we aim to locate the current authoritative version or update the affected content.
Content Corrections
If supporting content contains an inaccurate or misleading statement, it may be:
- Corrected
- Clarified
- Expanded
- Removed
- Replaced with better-supported information
We prefer correcting mistakes rather than preserving incorrect content simply because it has already been published.
Minor Corrections
Minor edits may include:
- Spelling fixes
- Grammar corrections
- Formatting improvements
- Broken internal links
- Small wording improvements
These changes may not require a formal correction notice if they do not materially change the meaning or result.
Significant Corrections
A significant correction may involve an error that materially changes:
- Calculator results
- Formula interpretation
- Technical guidance
- Important source data
- User understanding
Where appropriate, the page may be updated to explain that a meaningful correction was made.
Review Dates
A page’s Last Reviewed or Last Updated date should only change when a genuine review or meaningful update has occurred.
Dates should not be automatically refreshed merely to make content appear newer than it is.
Disagreements and Different Assumptions
Not every difference in result means the calculator is incorrect.
Concrete estimates can vary because of:
- Different measurements
- Different product yields
- Different waste allowances
- Different unit conventions
- Different project geometry
- Local construction practices
- Manufacturer-specific specifications
Where multiple reasonable approaches exist, we aim to explain the assumptions used by our calculator.
No Hidden Corrections
We do not intentionally leave known material calculation errors in place.
Likewise, we do not alter technical values simply to produce a more attractive result or match another website.
The calculation should follow the documented methodology and source data.
Professional and Engineering Matters
Crushed Concrete Calculator provides estimating and informational tools.
If a reported issue concerns structural design, safety, local code requirements, or another area requiring professional judgment, we may clarify the calculator’s limitations rather than attempting to provide engineering approval.

Our correction principle is simple:
If something is wrong, verify it, fix it, and make the tool clearer afterward.
