How do I convert MB to GB?
For this pair, use value × 0.001. A quick benchmark is 15 MB = 0.015 GB, which can help you check whether the result is in the expected range.

Megabyte (MB) is the starting unit on this page for a digital storage conversion.
Megabyte is part of the measurement language used in photos, documents, app downloads, and upload limits.
MB values are converted when decimal megabyte storage values but the final answer needs to be shown in a different unit.
Gigabyte (10^9 bytes) (GB) is the result unit produced by this MB to GB conversion.
Gigabyte (10^9 bytes) remains common in Gigabyte (10^9 bytes) appears in measurement references where GB is the expected label.
GB results are useful for working with values that are already written in GB, especially when converted data sizes are used in upload limits, storage planning, device comparisons, and download estimates.
Mathematically, gigabyte (10^9 bytes) (GB) = megabyte (MB) converted with the formula below.
1 MB = 0.001 GB
1 GB = 1,000 MB
Formula: value × 0.001
Example: 15 MB = 0.015 GB
Precision note: Keep enough decimal places to support your actual use. Check whether a product, operating system, or file tool is using decimal or binary units before comparing values.
1 MB = 0.001 GB
1 GB = 1,000 MB
| Megabyte [MB] | Gigabyte (10^9 bytes) [GB] |

Rounding depends on what the converted value is for. A casual estimate can be rounded for readability, while values used for file sizes and upload limits or storage plans and device capacity may need more decimal places.
A common mistake is assuming KB and KiB, MB and MiB, or GB and GiB always mean the same thing. For this pair, MB and MiB differ enough to matter in storage planning Keep the GB label attached to the number so the value is not misread
When reading the result in GB, remember that keep the gb label attached to the number so the value is not misread. If another source gives a different GB value, compare the number of decimal places first. If the difference is large, check the starting value, selected units, and direction.
For this pair, use value × 0.001. A quick benchmark is 15 MB = 0.015 GB, which can help you check whether the result is in the expected range.
It is the reverse direction. This page starts with MB and returns GB; the reverse starts with GB and returns MB.
Because Gigabyte (10^9 bytes) is the larger unit in this pair, the converted number is smaller than the starting MB value. The relationship is 1 MB = 0.001 GB.
