Calculator questions
How do I use the calculator?
Open the launcher with your shortcut and type the sum. There is no command to pick first. The answer shows as you type, and Enter copies it.
How do I convert units?
Type the amount, the unit, and the unit you want, like 10 km to miles. You can write to, in, into or as between them. Add units of the same kind in one line, like 5 km + 300 m to m.
Which units does it know?
52 units of length, weight, temperature, data size, time, speed, area and volume. Type a unit by its symbol or its name, so km and kilometers both work. For bytes, type the word.
Which currencies does it convert?
35 of them, including USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR, and the rest listed above. Write the code, or a symbol like $ for US dollars.
Where do the exchange rates come from?
From exchangerate-api.com. UtilEngine keeps each set of rates for two hours and then fetches a fresh one, so currency conversion needs a connection now and then. Math and units work without one.
Does it understand lakh and crore?
Yes, for money. Write 12 crore INR in USD and it converts the full amount. It also reads k, million and billion, and numbers grouped the Indian way, like 1,00,000.
Can I see past calculations?
Yes. Each answer you copy is saved. Run Calculator History to see them, copy one again, or delete the ones you no longer need.
Can I turn the conversions off?
Yes. Calculator settings has a switch for Units and one for Currencies. With both off, the calculator does math only.
Which browsers does it work in?
Chrome, Brave, Edge, and other Chromium browsers. Firefox support is on the roadmap.
