Convert KB to GB instantly. There are 1,048,576 KB in 1 GB using the binary standard your operating system reports, or 1,000,000 KB in 1 GB using the decimal standard drive manufacturers print on the box. Both modes are below, along with a full conversion table and worked examples for real file collections.

When thousands of kilobyte-sized files add up, expressing the total in gigabytes makes storage and quota planning far easier.
1 KB = 9.5367e-07 GB using the binary standard (1 step = ×1024), or 1.0000e-06 GB using the decimal standard (1 step = ×1000).
To convert, multiply your KB value by the factor above. For example, 5 KB = 4.7684e-06 GB (binary) or 5.0000e-06 GB (decimal).
Operating systems and memory use the binary standard, where each unit step is 1,024. Storage manufacturers and network speeds use the decimal standard, where each step is 1,000. This converter supports both — switch modes above to match your context.
Most people converting KB to GB are really asking a capacity question: will this pile of files fit on that drive? Because 1 GB holds 1,048,576 KB in binary terms, dividing the drive capacity by the average file size gives a usable answer straight away.
| Average file size | Typical example | Files per 1 GB | Files per 64 GB |
|---|---|---|---|
| 10 KB | Plain-text document | ~104,858 | ~6.7 million |
| 100 KB | Web-optimised JPEG | ~10,486 | ~671,000 |
| 500 KB | Short PDF or spreadsheet | ~2,097 | ~134,000 |
| 4,000 KB | Phone photo (4 MB) | ~262 | ~16,800 |
| 8,485 KB | MP3 album track at 320 kbps | ~124 | ~7,900 |
| 25,000 KB | Raw camera file (24 MP) | ~42 | ~2,680 |
Figures assume the binary standard and no filesystem overhead. In practice reserve about 5–10% for the filesystem itself, and remember a drive sold as 64 GB formats to roughly 59.6 GB because the label uses decimal gigabytes.
For a mixed collection of photos, songs and video, the how many files fit on a drive calculator does the arithmetic for you, and the storage calculator works the other way round — from a file library to the drive size you need. If your figures are in megabytes instead, use the MB to GB converter.
In binary: 1 GB = 1,048,576 KB. In decimal: 1 GB = 1,000,000 KB. So 1 KB = 9.5367e-07 GB (binary).
No — KB is smaller than GB. It takes 1,048,576 KB to make 1 GB (binary).
Multiply the KB value by 9.5367e-07 for binary, or 1.0000e-06 for decimal. You can also type any value into the converter above to see the result instantly.
Add up the total in KB, divide by 1,048,576 to get GB, then round up to the next drive size and add roughly 10% headroom for the filesystem. A 10.9 KB document needs no more than the smallest stick you can buy; 5,000,000 KB of photos is about 4.77 GB and fits comfortably on an 8 GB drive.
Use binary (1024) for RAM, file sizes shown by your operating system, and programming. Use decimal (1000) for advertised drive capacities and network speeds.
