Editorial &
calculation policy.
Convertly publishes interactive calculators, not anonymous answers. This page explains who maintains them, where formulas come from, how results are checked, and how to report a problem.
Last updated: July 19, 2026
Ownership and purpose
Convertly is independently created and maintained by Ved Prakash Dubey. Its purpose is to make common calculations understandable, adjustable, and quick to verify. Calculator inputs are processed in the browser where possible.
How tools are selected
A calculator is published when it solves a clear user task, exposes the inputs that materially affect the answer, and can explain the formula or assumptions behind its result. We do not publish a calculator solely to create another search-results page.
Sources and calculation review
- Standard physical conversions use internationally recognized unit definitions and fixed mathematical relationships.
- Currency results use the rate source and update timing stated in the converter and are estimates, not executable trading quotes.
- Financial, property, fitness, engineering, and science tools display important assumptions and link to primary or authoritative references where practical.
- Before release, each calculator is checked with known examples, boundary values, invalid inputs, and independent hand calculations.
- Material changes to formulas, assumptions, or source data are reviewed before publication.
Human review of generated support pages
Direct conversion result pages are support utilities and are excluded from search indexing unless they receive a separate usefulness and accuracy review. Convertly does not monetize those support pages.
Limits and professional advice
Results are estimates for informational and planning purposes. Tax, investment, health, religious, construction, laboratory, and legal decisions can depend on facts a general calculator cannot know. Users should confirm consequential decisions with a qualified professional or relevant authority.
Corrections and contact
To report a calculation error, include the calculator name, inputs, expected result, and supporting source. Contact the maintainer through the public GitHub issue tracker or the Kavexa contact page. Valid corrections are prioritized and the affected formula is re-tested before an update is published.
