To convert megabytes to gigabytes (decimal), divide by 1,000. In the decimal (SI) system used by storage manufacturers, 1 GB = 1,000 MB.
1 MB = 0.001 GB
Convert 2,500 MB to GB: 2,500 ÷ 1,000 = 2.5 GB
Convert 750 MB to GB: 750 ÷ 1,000 = 0.75 GB
To convert GB to MB, multiply by 1,000.
\u2022 1 MB is roughly the size of a short eBook or a medium-quality photo.
\u2022 100 MB is about the size of a 3-minute MP3 podcast at high quality.
\u2022 1 GB (1,000 MB) is about 250 MP3 songs or 500 high-resolution photos.
\u2022 A Netflix movie in HD uses about 3,000-6,000 MB (3-6 GB).
Megabytes and gigabytes are the most commonly encountered digital storage units. Understanding the relationship between them is essential for managing phone storage, choosing data plans, evaluating cloud storage, and downloading files.
In the decimal system (used by storage manufacturers and mobile carriers), 1 GB = 1,000 MB. In the binary system (used by operating systems), 1 GiB = 1,024 MiB. This is why a "500 GB" hard drive shows about 465 GB in your operating system — the manufacturer uses decimal, your OS uses binary.
Mobile data plans are measured in GB. Knowing how many MB your activities use helps you stay within limits: a 5-minute YouTube video at 720p uses about 50-100 MB, browsing web pages uses about 2-5 MB each, and streaming music uses about 1-2 MB per minute.
A typical photo is 3-10 MB, a 3-minute MP3 song is 3-5 MB, a 1-hour podcast is 50-100 MB, and a high-definition movie is 4,000-8,000 MB (4-8 GB). An iPhone app averages about 100-200 MB.
In the decimal system (used by storage manufacturers), 1 GB = 1,000 MB. In the binary system (used by operating systems), 1 GiB = 1,024 MiB.
It depends on the system. Storage manufacturers and mobile carriers use decimal (1 GB = 1,000 MB). Operating systems often use binary (1 GiB = 1,024 MiB). This converter uses the decimal system.
500 MB is 0.5 GB.
Hard drive manufacturers use decimal (1 TB = 1,000 GB), but your operating system displays in binary (1 TiB = 1,024 GiB). A "1 TB" drive is about 931 GiB in your OS.
