FAQ
Frequently asked questions
What is the difference between GB and GiB?
A gigabyte (GB) is 1,000,000,000 bytes, while a gibibyte (GiB) is 1,073,741,824 bytes (1024³). Drive makers use GB; many operating systems report GiB, which is why a 1 TB drive shows about 931 GiB.
How do I convert Mbps to MB/s?
Divide by 8, because there are 8 bits in a byte. A 100 Mbps connection downloads at up to 12.5 MB/s.
How do I convert Celsius to Fahrenheit?
Multiply by 9/5 and add 32. So 20 °C = 68 °F. To go back, subtract 32 and multiply by 5/9.
Are US and UK gallons the same?
No. A US gallon is 3.785 litres and a UK (imperial) gallon is 4.546 litres. US and UK pints and fluid ounces differ too, so both are listed separately.
How long is a month or a year in this converter?
We use averages from the Gregorian calendar: a year is 365.2425 days and a month is one twelfth of that (about 30.44 days).
