Convert length, weight, temperature and volume instantly, or check a live currency exchange rate.
Fetching live rates…
The unit converter uses fixed, standard conversion factors, so results are exact. The currency converter fetches live foreign exchange rates from a public rates API when the page loads; if the request fails (for example, no internet connection), it falls back to approximate reference rates and flags the result as an estimate.
How current are the currency rates?
Rates are fetched fresh each time you load the page and are typically updated at least daily by the data provider. The exact update time is shown next to the result.
Which temperature scales are supported?
Celsius, Fahrenheit, and Kelvin.
