About Converter Units
Converter Units is a small, independent set of conversion tools built and maintained by one person.
Who runs this site
Converter Units is operated by Cedrick Reese under Ready Utilities. There is no team, no company behind it, and no editorial staff. One person builds the tools, checks the figures, and fixes them when they are wrong.
How the numbers are sourced
Physical unit conversion factors come from the NIST Guide to the SI, Appendix B, published by the US National Institute of Standards and Technology. NIST prints exact factors in boldface and rounds the rest to the digits shown, and this site follows the same convention: every conversion page states whether its factor is exact or rounded.
Ingredient weights for the cooking converters come from King Arthur Baking's ingredient weight chart. That source was chosen deliberately, and the cups-to-grams page discloses that other reputable sources publish different figures for flour rather than presenting one number as settled.
Where a competing page publishes a figure that appears to be wrong, this site says so plainly and shows the correct value with its source, instead of quietly disagreeing.
Accuracy and limits
These tools are provided for general reference. For engineering work, medical decisions, legal filings or anything where a wrong number carries real cost, verify against a manufacturer specification, the applicable standard, or a qualified professional. A converted figure inherits whatever precision the original measurement had, so quoting a result to more decimal places than the input justifies is misleading rather than helpful.
The tools run entirely in your browser. Nothing you type into a converter is sent anywhere.
Corrections
If a figure here is wrong, please say so through the contact page. Conversion errors get fixed quickly, and reporting one really does help.
Two housekeeping pages sit alongside this one. The privacy policy sets out what the site keeps in your browser and what it sends anywhere else, which is nothing at all. The terms of service carries the accuracy disclaimer that applies to every figure published here.
