Frequently Asked Questions

QHow many MB is 1 GB?

Using the binary standard (used by Windows, macOS, and most operating systems): 1 GB = 1,024 MB. Using the decimal standard (used in hard drive marketing): 1 GB = 1,000 MB. Always check which standard your device or service uses.

QIs 1000 MB equal to 1 GB?

In the decimal system (SI), 1 GB = 1,000 MB. In the binary system used by operating systems, 1 GB = 1,024 MB. Hard drive manufacturers often use the 1,000 MB definition, which is why a '500 GB' drive appears as ~465 GB on your computer.

QHow many MB is a 2-hour HD movie?

A 2-hour HD (1080p) movie typically ranges from 3,000–8,000 MB (3–8 GB) depending on encoding. A lower-quality 720p version might be 1,500–3,000 MB, while 4K HDR can reach 40,000–80,000 MB (40–80 GB).

QWhy does my 256 GB phone show less available storage?

Phone manufacturers measure storage in decimal GB (1 GB = 1,000 MB), but your device's OS measures in binary GB (1 GB = 1,024 MB). A 256 decimal GB drive is only about 238 binary GB. Pre-installed apps and the OS also consume some storage.

Quick reference and common mistakes

Use the quick table for fast lookups and the formula when accuracy matters. Keep more decimals during intermediate steps, then round only for the final number you plan to show or report.

Mixing decimal and binary data assumptions without checking context.
Confusing bits and bytes in transfer or storage estimates.
Ignoring unit case, which changes meaning in some tools.
