Megabytes to Gigabytes Converter (MB to GB)
Convert megabytes to gigabytes instantly. 1 MB = 0.000977 GB. Includes the formula, a full conversion table and a calculator that works offline.
The formula
To convert megabytes to gigabytes, multiply by 0.000977:
GB = MB × 0.000977Going the other way, divide instead — or multiply by 1,024, which is the same thing:
MB = GB × 1,024Megabytes to Gigabytes conversion table

What that actually looks like
A conversion factor is hard to judge on its own. These are quantities most people already have a feel for, converted for you:
- A high-quality photo is about 5 MB — 0.004883 GB
- A three-minute song is around 8 MB — 0.007812 GB
- An app download is often 150 MB — 0.1465 GB
Why both units are still in use
Digital storage has a genuine ambiguity: 1 GB can mean 1,024 MB (the binary sense your operating system uses) or 1,000 MB (the decimal sense drive manufacturers print on the box). This page uses the binary values, which is why a 1 TB drive shows up as roughly 931 GB once it is plugged in. Nothing is missing — the two sides are simply counting differently.
Mistakes worth avoiding
Do not mix bits and bytes. Broadband is sold in megabits per second and files are measured in megabytes, so a 100 Mb connection downloads at about 12.5 MB per second, not 100. The eight-to-one difference is why a download always looks slower than the advertised speed.
The other habit worth breaking is rounding too early. Convert first, round once at the end, and you avoid the drift that turns a small approximation into a visible error by the third calculation.
Doing it in your head
When you only need a rough answer, divide by 1,024 — which is exact. Ten megabytes works out at roughly 0.009766 gigabytes that way, against 0.009766 exactly. An estimate is enough for deciding whether something will fit or whether a figure sounds plausible. When the number has to be right — because you are buying, cooking or building to it — use the calculator and let it carry the decimals.
Common questions
How many gigabytes are in one megabyte?
One megabyte equals 0.000977 gigabytes. The calculator above handles any value, including decimals and very large numbers, and updates as you type.
Is this an exact conversion?
The factor is accurate to the precision shown, which is far beyond what any practical measurement requires. The table rounds for readability; the calculator does not.
Does this work offline?
Yes. The conversion runs in your browser with no network request, so it works on a plane, in a basement, or on a phone with no signal once the page has loaded.
