Our editorial standards
Calcovate publishes free calculators and converters. Every tool is built to give a correct answer first and a quick explanation second. This page explains how we build, check and update them.
How we build a calculator
- Each calculator uses a published, standard formula, shown on the page together with a worked example.
- Inputs are validated, so impossible values return a clear message instead of a wrong number.
- Calculations run in your browser. The numbers you enter are not sent to our servers.
How we check them
- Every worked example is run through the live calculator and compared with the figure printed on the page.
- An automated check visits every calculator daily and flags broken pages, missing tools or structural problems.
- Conversion factors come from standard definitions (SI and NIST references).
Corrections
If you find a wrong result, tell us through the contact page with the calculator name and the numbers you used. We review every report and fix confirmed errors quickly.
Important note
Health, financial and legal calculators give general estimates for information only. They are not professional advice. See our disclaimer.
