Converters
Convert units and currencies, and count the time between dates exactly. The unit converter covers length, weight and temperature using exact conversion factors rather than rounded ones. The currency converter uses the European Central Bank's published reference rates, with the date shown. The age, date difference and time duration calculators count forwards through the calendar, so months of different lengths and leap years come out right.

Questions about converters calculators
Are the currency rates live?
No. The currency converter uses the European Central Bank's reference rates for the date shown on the page. For a transfer or payment, check the rate your bank or provider actually offers, which will include its margin.
