MB to GB●
Megabytes in. Gigabytes out. Check file sizes and storage in a moment.
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
gigabytes = megabytes ÷ 1000
Divide the number of megabytes by 1000 to get gigabytes. To go the other way, multiply by the same number.
A worked example
For 1500 MB, divide 1500 by 1000. The result is approximately 1.5 GB.
1500 ÷ 1000 ≈ 1.5 GB

Digital storage conversions
For files, phones and downloads.
Use this conversion for file sizes and storage plans. This page uses decimal units, where 1 GB is 1000 MB, the way storage makers and most operating systems label capacity. Windows often shows binary units: choose GiB and MiB in the menu if you need them.
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
Is 1 GB 1000 or 1024 MB?
Decimal gigabytes (GB) use 1000 MB. Binary gibibytes (GiB) use 1024 MiB.
How many gigabytes are in 4700 megabytes?
4700 MB is approximately 4.7 GB. The converter can show more significant digits or round to a chosen number of decimal places.
