Data Storage Converter helps you convert between data units without a spreadsheet. Type Value into Data Storage; each keystroke re-runs the math. Data Storage displays each intermediate figure as well. Data Storage suits budgeting and planning checks. Data Storage runs in your browser. Unit Conversion data stays in the tab. Looking for gb to mb data storage conversion calculator or free online data storage converter? Data Storage covers both. The labels in Data Storage match the terms in its result. Data Storage stays bookmarked for next time.
What the defaults give
1 GB = 1,024 MB. The tool converts the input to bytes first — 1,073,741,824 of them — then divides by the bytes in a megabyte.
This is the binary ladder (KiB, MiB, GiB) under the familiar KB, MB and GB labels.
How the conversion works
result = value × bytes[from] ÷ bytes[to]
Each step on the ladder is 1,024 of the one below: 1,024 bytes to a kilobyte, 1,024 kilobytes to a megabyte, and so on up to a petabyte. Converting through bytes means the tool never needs a table of pairwise factors — one multiplication and one division covers every pair of units it offers.
Worked examples
1 GB → 1,024.0000 MB
2 GB → 2,048.0000 MB
0.5 GB → 512.0000 MB
1 TB → 1,048,576 MB
1 MB → 1,024 KB
The pattern is that each step up the ladder multiplies by 1,024, so a jump of three steps — bytes to gigabytes — multiplies by 1,073,741,824.
Why the drive in your hand disagrees
Drive and memory-card makers use decimal units: a marketed 1 TB is 1,000,000,000,000 bytes. Read back in binary units, that is 931 GiB, so a “1 TB” drive shows 931 GB in the operating system and about 7% of the capacity appears to vanish. Nothing is missing — the label and the file manager are simply counting on different ladders.
The same gap explains why a 128 GB phone reports about 119 GB of usable space before system files, and why a 32 GB card formats to roughly 29.8 GB. When you are checking whether a file will fit, convert with this tool and then subtract a few percent for formatting metadata.
Practical sizes
A four-minute song at 320 kbps is about 9.4 MB, so 1,000 songs is roughly 9 GB. A two-hour film at 8 Mbps is about 7.2 GB. A 1,024 × 1,024 photograph shot in raw is typically 20–30 MB. Video is what fills drives: a mirrorless camera recording at 200 Mbps writes about 1.5 GB per minute, which is 90 GB an hour.
Cloud quotas are usually decimal, so a 15 GB free tier is about 13.9 GiB as your file browser counts it. Budget by the smaller number.
Frequently Asked Questions
Is 1 GB equal to 1,024 MB or 1,000 MB?
Both conventions exist. This tool uses 1,024, the binary ladder that operating systems display; drive manufacturers use 1,000.
Why does my 1 TB drive show 931 GB?
It holds 1,000,000,000,000 bytes. Divided by 1,024 four times, that is 931 GiB, and the file manager labels it GB.
How many MB are in a TB?
1,048,576 using 1,024-step units, or exactly 1,000,000 using decimal units. The tool returns the first.
How many photos fit in 64 GB?
At 25 MB a raw file, about 2,560 shots. JPEGs at 6 MB would be nearer 10,600. Formatting and the operating system take a few percent first.
Can I convert between bits and bytes here?
No — the inputs are B, KB, MB, GB, TB and PB, all bytes. Multiply by eight to go from bytes to bits, for example when comparing to a network speed in Mbps.
