Megabytes to Kilobits formula
Converting megabytes to kilobits is a single multiplication by 8000.
Kb = MB × 8000
Put another way, one megabyte is exactly 8,000 kilobits.
Why this factor: the megabyte and the kilobit are both defined against the byte, so dividing one definition by the other gives 8000 directly. Both definitions are set out in full below.
To go the other way, divide by 8000 — or use the Kilobits to Megabytes converter, which is the same calculation reversed.
Worked example
Given 500 MB, multiplying by 8000 yields 4000000 Kb.
500 MB × 8000 = 4000000 Kb
The converter above does this for any value you type, in either direction.
What is a megabyte?
A megabyte is one million bytes, the familiar unit for photos, songs and app sizes.
Definition: Exactly 1,000,000 bytes under SI prefixes. The binary mebibyte (MiB) is 1,048,576 bytes.
Where it is used: Photo and audio file sizes, app downloads, and mobile data allowances.
What is a kilobit?
A kilobit is 1,000 bits, used almost exclusively for data rates.
Definition: Exactly 1,000 bits, so exactly 125 bytes.
Where it is used: Audio and video bitrates, and legacy connection speeds.
Megabytes vs Kilobits
The megabyte and the kilobit belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
