About HowMany.wiki

HowMany.wiki is a reference library of measurement answers — a collection of calculators and conversion charts, not a collaboratively edited wiki. It answers practical questions such as how many grams are in a cup of a given ingredient, or how to convert between units of volume, weight, length and temperature, using a fixed, transparent method rather than user-submitted content.

Who runs it

HowMany.wiki is built and maintained by Adilson Fernandes, an electronics engineer who has been developing free online conversion tools since 2014 as the creator of CoolConversion.com. HowMany.wiki has been online since 2016 and is operated as part of the same effort — a focused companion to CoolConversion dedicated to cooking, recipe and everyday measurement conversions.

How the numbers are calculated

Volume-to-weight and weight-to-volume results are density-based: each ingredient uses a reference density (primarily the FAO/INFOODS density database, complemented by published reference values), and unit conversions use standard defined factors. Results are rounded to three significant figures — precise enough for kitchen and everyday use while avoiding a false impression of exactness. Figures are provided as-is; for anything critical, confirm against a primary source.
