How many Megabytes (MB) make 1 Gigabyte (GB)?

In binary system (RAM & OS), 1 GB = 1024 MB. In decimal metric system (Hard drives/SSD), 1 GB = 1000 MB.

How do I convert MB to GB manually?

For Binary (RAM/OS), divide MB by 1024. For Decimal (HDD/SSD), divide MB by 1000.

What is the difference between MB and Mb?

MB (Megabytes) measures file storage capacity. Mb (Megabits) measures internet connection speed. 1 MB equals 8 Mb.

Understanding Megabytes to Gigabytes Conversion

Whether you are configuring cloud servers, buying a smartphone with 128GB of storage, checking available RAM on your laptop, or managing file uploads, understanding how Megabytes (MB) translate into Gigabytes (GB) is crucial for digital media management and IT operations.

Binary Standard (Base-2 / IEC)

Computers and operating systems (such as Windows, Linux, and macOS RAM management) use binary logic where 1 Gigabyte (GiB) = 1,024 Megabytes (MiB) (or $2^{10}$).

Formula: GB = MB ÷ 1024

Decimal Standard (Base-10 / SI)

Storage hardware manufacturers (Samsung, SanDisk, Western Digital) and telecommunication networks use the International System of Units (SI) where 1 Gigabyte (GB) = 1,000 Megabytes (MB) ($10^3$).

Formula: GB = MB ÷ 1000

Why Does Your 500GB SSD Show as ~465GB in Windows?

This common discrepancy happens due to the clash between decimal and binary standards. A manufacturer sells a 500 GB drive calculated in decimal ($500 \times 1,000,000,000\text{ bytes} = 500,000,000,000\text{ bytes}$). When connected to Windows, the operating system divides this number by $1024^3$ ($1,073,741,824\text{ bytes per GiB}$), resulting in approximately 465.66 GiB. Our converter allows you to switch seamlessly between both calculation bases so you always get the precise value you need.
