How to convert megabytes to gigabytes

Multiply the number of megabytes by 0.001, or divide by 1,000.

GB = MB × 0.001 (or MB ÷ 1,000)

Example: 1,500 MB × 0.001 = 1.5 GB

This page uses decimal (SI) units: 1 GB = 1,000 MB, as on drive packaging, phone data plans and macOS. Windows and some apps use binary units, where 1 "GB" (really a GiB) = 1,024 MiB. See bits, bytes, KB vs KiB for the full story.

Gigabyte (GB)

A gigabyte is 1,000,000,000 bytes in the decimal convention used on drive packaging, phone plans and cloud storage.
