Frequently asked questions
How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 and add 32. So 20°C becomes 68°F. Pick the Temperature tab above and it does it for you, in either direction.
How many pounds are in a kilogram?
One kilogram equals about 2.20462 pounds, and one pound is roughly 0.45359 kilograms. Use the Weight tab for exact figures at any value.
What is the difference between GB and GiB?
A gigabyte is 1,000,000,000 bytes; a gibibyte is 1,073,741,824. Drive manufacturers advertise in GB while operating systems often report in GiB, which is why a new drive looks smaller than the box promised.
