Utility Commons

What: Utility Commons is a free collection of calculators, conversions, reference charts, and quizzes built to answer everyday questions fast. It spans everyday calculators like the age calculator and body fat percentage calculator, reference charts including a metric conversion chart and TV size and viewing distance chart, unit conversions like cups to ounces and our Roman numeral converter, plus a set of quizzes for when you’d rather find out which animal matches you.

Why: Utility Commons is where our network grows up. We started by building single-purpose micro-sites for everyday needs — and they work. But a search for “how many cups in an ounce” and a search for “what’s my shoe size” deserve the same quality of answer in the same place, without a dozen scattered domains. Utility Commons is the common ground: one site, built to be genuinely more useful than whatever currently shows up first.

for Good: 20% of revenue from this site and others like it go to community & non-profit organizations. Read more about our for Good aspect if you’d like.

We get bored easily, we like building things, and we like helping people. Utility Commons keeps all three going at once.
