FAQ
How many kilobytes make up one megabyte?
One megabyte holds 1,024 kilobytes, or 1,048,576 bytes, on the binary scale this converter uses. The decimal convention of the SI puts 1,000 KB in a megabyte instead, and the IEC name for the 1024-based unit is the mebibyte (MiB).
What is the formula to convert megabytes to kilobytes?
Multiply the megabyte value by 1,024: 1 MB = 1,024 KB, 0.5 MB = 512 KB and 25 MB = 25,600 KB. Dividing by 1,024 takes kilobytes back to megabytes.
Why are attachment limits quoted in MB but image sizes in KB?
Because the two units are a factor of 1,024 apart, and each one fits the size it describes. A 25 MB mail limit is 25,600 KB, while a compressed photo usually weighs 100–500 KB — so somewhere between 50 and 250 of them fit into one message.
