How do I convert GB to MB?
For this pair, use value × 1000. A quick benchmark is 15 GB = 15,000 MB, which can help you check whether the result is in the expected range.

Gigabyte (GB) is the starting unit on this page for a digital storage conversion.
Gigabyte is part of the measurement language used in phones, drives, cloud storage, videos, and data plans.
GB values are converted when decimal gigabyte storage values but the final answer needs to be shown in a different unit.
Megabyte (10^6 bytes) (MB) is the result unit produced by this GB to MB conversion.
Megabyte (10^6 bytes) remains common in Megabyte (10^6 bytes) appears in measurement references where MB is the expected label.
MB results are useful for working with values that are already written in MB, especially when converted data sizes are used in upload limits, storage planning, device comparisons, and download estimates.
Mathematically, megabyte (10^6 bytes) (MB) = gigabyte (GB) converted with the formula below.
1 GB = 1,000 MB
1 MB = 0.001 GB
Formula: value × 1000
Example: 15 GB = 15,000 MB
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 GB = 1,000 MB
1 MB = 0.001 GB
| Gigabyte [GB] | Megabyte (10^6 bytes) [MB] |
|---|---|
| 0.01 GB | 10 MB |
| 0.1 GB | 100 MB |
| 1 GB | 1,000 MB |
| 2 GB | 2,000 MB |
| 5 GB | 5,000 MB |
| 10 GB | 10,000 MB |
| 20 GB | 20,000 MB |
| 50 GB | 50,000 MB |
| 100 GB | 100,000 MB |
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, Advertised storage often uses GB, while operating systems may display GiB-like values Keep the MB label attached to the number so the value is not misread
When reading the result in MB, remember that keep the mb label attached to the number so the value is not misread. If another source gives a different MB 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 × 1000. A quick benchmark is 15 GB = 15,000 MB, which can help you check whether the result is in the expected range.
It is the reverse direction. This page starts with GB and returns MB; the reverse starts with MB and returns GB.
Because Megabyte (10^6 bytes) is the smaller unit in this pair, the converted number is larger than the starting GB value. The relationship is 1 GB = 1,000 MB.
