Frequently asked questions
How accurate are the calculations?
The converter uses exact international conversion factors (for example, 1 mile = exactly 1609.344 meters), so results are as accurate as possible within display rounding.
Why is data measured as 1 KB = 1024 bytes, not 1000?
We use the binary system (1024), traditionally used by operating systems and most file managers when displaying file sizes.
Does the converter account for temperature’s different formulas?
Yes. Unlike other quantities, temperature isn’t converted by simple multiplication — the tool uses the correct formulas accounting for each scale’s offset (Celsius, Fahrenheit, Kelvin).
Can this tool convert currencies?
No. Exchange rates change by the minute and require a connection to an external server, while every kyrlat.com tool runs entirely locally, with no server requests.
Is my input stored anywhere?
No. All calculations happen locally in your browser using JavaScript. Your data is never sent to a server.
