Questions
Are US and UK gallons the same?
No. A US gallon is 3.785 liters, a UK (imperial) gallon is 4.546 liters. Cups, pints and fluid ounces in this converter are US units.
What is the difference between MB and MiB?
MB uses powers of 1000 (1 MB = 1,000,000 bytes), the way disk makers count. MiB uses powers of 1024 (1 MiB = 1,048,576 bytes), the way many operating systems count. That is why a "1 TB" drive shows up as about 931 GiB.
How precise are the results?
Conversions use the exact official factors (for example 1 inch = 2.54 cm exactly) and show up to 10 significant digits.
