Bytes to KB
How many kilobytes are in a number of bytes.
The conversion
Divide the byte count by 1,000 for KB. Divide by 1,024 only when you want KiB. A 1,500 byte file is 1.5 KB, not 1.5 KiB.
Which system to use
Use decimal KB, MB, and GB when you are matching a label that counts by thousands. Use binary KiB, MiB, and GiB when a spec counts by 1,024. Do not add the two together as if they were the same unit.

Questions
How many KB are in 1 MB?
In the decimal system used by default, 1 MB = 1,000 KB. In the binary system, 1 MiB = 1,024 KiB. KB and KiB are different units.
What is the difference between MB and MiB?
MB is a decimal megabyte: 1,000,000 bytes. MiB is a binary mebibyte: 1,048,576 bytes. This calculator never mixes the two in one result.
How many bytes are in a GB?
In decimal units, 1 GB = 1,000,000,000 bytes. In binary units, 1 GiB = 1,073,741,824 bytes.
Is 1 MB exactly 1024 KB?
No. That statement mixes the systems. 1 MB is 1,000 KB. 1 MiB is 1,024 KiB.
