Megabits to megabytes●
Megabits in. Megabytes out. See real download speed from your plan.
Digital storage
1 byte = 8 bits. Decimal: kB, MB, GB (×1,000). Binary: KiB, MiB, GiB (×1,024).
Definitions: NIST binary prefixes ↗Use a decimal point, for example 2.54. Scientific notation works too: 1e3.

Pick an example to startThe formula
megabytes = megabits ÷ 8
Divide the number of megabits by 8 to get megabytes. To go the other way, multiply by the same number.
A worked example
For 100 Mbit, divide 100 by 8. The result is approximately 12.5 MB.
100 ÷ 8 ≈ 12.5 MB

Digital storage conversions
For internet speed and downloads.
Internet plans are sold in megabits per second, while files are measured in megabytes. Divide megabits by 8 to get megabytes: a 100 Mbit line moves at best 12.5 MB each second.
Calculation details & precision
A byte is 8 bits. Decimal prefixes use powers of 1,000: 1 kB = 1,000 B and 1 GB = 1,000,000,000 B. Binary prefixes use powers of 1,024: 1 KiB = 1,024 B and 1 GiB = 1,073,741,824 B. Calculations use bytes as the base unit.
Automatic displays up to 12 significant digits. Choose 2, 4 or 6 decimal places in Precision for a shorter result. Displayed results are rounded; very large or small values use scientific notation.
Common questions
Why divide by 8?
There are 8 bits in a byte, so megabits divided by 8 gives megabytes.
How many megabytes are in 100 megabits?
100 Mbit is approximately 12.5 MB. The converter can show more significant digits or round to a chosen number of decimal places.
