How to use it

  1. Type the value in the gigabits box.
  2. Read the result in megabytes as you type, and pick the precision you need.
  3. Swap the direction to convert back, or copy the result.

How it is calculated

MB = Gbit × 125

Multiply the value in gigabits by 125 to get megabytes.

Example

To convert 25 Gbit to megabytes: 25 × 125 = 3,125 MB.

About the units

Gigabit
A decimal unit equal to exactly 10^9 bits, which is 125,000,000 bytes.
Megabyte
A decimal unit equal to exactly 1,000,000 bytes (10^6), different from the binary mebibyte of 1,048,576 bytes.

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
  • Both unit factors are exact by their official definitions.

Questions about this tool

How many megabytes are in one gigabit?

1 Gbit = 125 MB exactly.

How do I convert gigabits to megabytes?

Use MB = Gbit × 125. For example, 25 Gbit = 3,125 MB.

How many gigabits are in one megabyte?

1 MB = 0.008 Gbit.

Why does a 1 TB drive show about 931 GB on my computer?

Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.

What is the difference between a kilobyte and a kibibyte?

A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
