FAQ
How do I convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. For example, 20°C is 20 × 1.8 + 32 = 68°F. Select the Temperature category and this tool does it for you, both directions plus Kelvin.
How many pounds is a kilogram?
One kilogram is about 2.2046 pounds; one pound is 453.592 grams. Pick the Weight category to convert any value precisely between metric and imperial.
Are data sizes calculated with 1024 or 1000?
This tool uses 1024 (binary: 1 KB = 1024 bytes, 1 MB = 1024 KB), which is how operating systems traditionally report file and memory sizes. Storage manufacturers sometimes use 1000 (decimal) instead, which is why a "1 TB" drive shows as slightly less in your OS.
Is the conversion done on a server?
No — all conversion factors are built into the page and calculated in your browser. Nothing you type is sent anywhere.
