Google Search has a unit converter. Type your conversion into the search box on google.com, or search for unit converter to open it on its own. Google’s own example is Celsius to Fahrenheit or cups to liters.
You can search from Chrome’s address bar too. If Google is your default search engine, type the conversion there and press Enter. In some countries Google is Chrome’s default, and in others Chrome asks you to pick one.
