When should you use Converters tools?
This category is for when you need to turn one form into another: kilometers to miles, rupiah to a foreign currency, WIB time to another time zone, Gregorian dates to Hijri, a Unix timestamp to a date, CSV to JSON, or a HEX color code to RGB and HSL.
The Currency Converter fetches reference exchange rates from an outside service, so it needs an internet connection. The other converters run entirely in your browser.
