When you need to convert megabits to kilobytes

Checking whether a file fits inside a storage or upload limit.
Working out how much of a mobile data allowance a download will use.
Reconciling the capacity printed on a drive with the smaller figure the operating system reports.

Common mistakes to avoid

Dividing when you should multiply. Because 1 megabit = 125 kilobytes, the answer should be larger than the number you started with.
Treating 1 kB as 1,024 bytes. Storage and network figures use decimal units of 1,000; operating systems usually report binary units of 1,024, which is why a 1 TB drive shows as about 931 GiB.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round to two decimals for human-readable sizes. When you are checking a hard limit, use the exact figure: a file 0.4% over an upload cap still fails.

How these units are defined

Megabit (Mb): 1,000,000 bits — internet speeds are quoted in megabits per second. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Kilobyte (kB): 1,000 bytes in decimal (SI) notation. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
