How it works
The converter covers length, weight, and temperature using standard, fixed conversion factors — accurate every time, with no internet connection needed once the page is loaded. Pick a category, choose your "from" and "to" units, and the result updates instantly as you type.
Currency conversion uses live exchange rates fetched directly in your browser each time you load the page. Handy for a quick estimate — for example, roughly what an amount in one currency is worth in another before a trip — though real transfers will include a spread or fee your bank or provider applies on top.
Converter FAQ
Which units are supported?
Length (metres, kilometres, centimetres, millimetres, miles, yards, feet, inches), weight (kilograms, grams, milligrams, pounds, ounces, tonnes), temperature (Celsius, Fahrenheit, Kelvin), and currency using live exchange rates.
How accurate are the conversions?
Length, weight, and temperature use standard, fixed conversion factors, so they're exact. Currency rates are fetched live but are mid-market reference rates — always check with your bank or provider before an actual transaction.
Do I need an internet connection?
Only for currency conversion, since exchange rates are fetched live. Length, weight, and temperature conversion work without a connection once the page has loaded.
