How this is calculated
GB = MB ÷ 1000 (SI decimal — drives and data plans) · 1 GiB = 1024 MiB (binary — what Windows shows)
Storage is sold in decimal (1 GB = 1000 MB) but Windows reports binary (1 GiB = 1024 MiB) — which is why a "500 GB" drive shows as 465 "GB". Both are correct; they are different units wearing the same letters. This converter uses decimal because that is how data plans, drives, and download sizes are labelled.
The chart uses real objects — a song, a photo, an HD movie, a game download — so the numbers have anchors, not just zeros.
Frequently asked questions
How many MB in a GB?
1,000 MB in the decimal (SI) system that storage makers, data plans, and download counters use. The binary gibibyte (GiB) that Windows displays is 1,024 MiB — a different, similarly-named unit, which is the whole confusion.
Why does my 500 GB drive show only 465 GB?
The drive is 500 decimal GB (500,000,000,000 bytes). Windows divides by 1024³ and labels the result "GB" when it is really GiB: 500×10⁹ ÷ 1024³ = 465.7 GiB. Nothing is missing — the units differ.
Is 1 GB of data a lot?
It is roughly an hour of HD streaming, 200 songs, or a few hundred web pages with images. A 50 GB monthly plan comfortably covers everyday browsing and social apps; video is what eats gigabytes.
How do I convert GB to TB?
Divide by 1000 again: 2,000 GB = 2 TB. Each step in the decimal ladder (KB → MB → GB → TB) is ×1000; this converter handles the MB ↔ GB step both directions.
