A megabyte (MB) contains one million bytes. A mebibyte (MiB) contains 1,048,576 bytes. A bit is one eighth of a byte, so a 20 megabit/second connection would ideally transfer a 100 MB file in 40 seconds before overhead.
US and Imperial gallons are different volumes. Our volume converter names each explicitly. Cooking cups also differ by regional convention. A mass-to-volume conversion additionally needs density and cannot assume every ingredient behaves like water.
Absolute temperatures include an offset. Zero Celsius is 32 Fahrenheit. Differences do not: a 10 Celsius increase is an 18 Fahrenheit increase. Use the interval tool for changes and the temperature converter for measurements.
