Megabits to Megabytes
A megabit is 1,000 kilobits, the unit internet providers use to advertise download and upload speeds (Mbps). A megabyte is 1,000 kilobytes, a common unit for document, photo, and small app file sizes. 1 Mbit equals 0.125 MB, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
MB = Mbit × 0.125
Mbit = MB × 8
Worked example: 5 Mbit × 0.125 = 0.625 MB.
