About Unitzy

Unitzy is a set of free converters and calculators for everyday numbers: currencies, measurements, dates, percentages and money.

Unit conversions and calculators run in your browser, so results appear as you type. Each tool explains how its result is calculated, so you can check the working yourself. Unit factors use internationally agreed definitions, such as the inch being exactly 2.54 cm.

Exchange rates come from ExchangeRate-API and are updated once a day; each conversion shows when its rates were published. Rate history comes from the European Central Bank.
