Quick answer
1 GB = 1,000,000 KB (decimal) and 1 GiB = 1,048,576 KiB (binary). To convert KB to GB, divide by 1,000,000. To convert KiB to GiB, divide by 1,048,576. Example: 200,000 KB = 0.2 GB, while 200,000 KiB is about 0.190735 GiB.
How to convert KB to GB
GB = KB ÷ 1,000,000. GiB = KiB ÷ 1,048,576 (1,024 × 1,024). It is two prefix steps, kilo to mega to giga, so the divisor is the square of the single-step factor. The gap between the decimal and binary answers is about 4.9% here. For one step at a time, use the KB to MB converter and then the MB to GB converter.
- 500,000 KB is 0.5 GB decimal. As KiB, 500,000 is about 0.476837 GiB.
- 1,000,000 KB is exactly 1 GB. As KiB, it is about 0.953674 GiB.
- 1,048,576 KiB is exactly 1 GiB. As KB, it is 1.048576 GB.
- Fast estimate: move the decimal point six places left. 3,500,000 KB is about 3.5 GB.

Which one is bigger, KB or GB?
A gigabyte is far larger. One GB holds 1,000,000 KB in decimal units, or 1,048,576 KiB in binary units. A 200,000 KB file is only 0.2 GB, one fifth of a gigabyte.
Frequently asked questions
Is 1024 KB equal to 1 GB?
No. 1,024 KB is 1.024 MB, about 0.001024 GB. It takes 1,000,000 KB to make 1 GB in decimal units, or 1,048,576 KiB to make 1 GiB in binary units.
What is larger, KB or GB?
GB is larger. 1 GB = 1,000,000 KB in decimal units and 1 GiB = 1,048,576 KiB in binary units.
Is 1 kB 1000 or 1024?
The SI kilobyte (kB or KB) is 1,000 bytes. The kibibyte (KiB) is 1,024 bytes. Windows and some other software print KB for the 1,024-byte unit.
How many MB are in 1 GB?
1 GB = 1,000 MB in decimal units. 1 GiB = 1,024 MiB in binary units. The GB to MB converter shows both.
200000 KB in GB?
200,000 KB = 0.2 GB in decimal units. If the 200,000 is KiB, it is about 0.190735 GiB.
How many KB is 5 GB?
5 GB = 5,000,000 KB in decimal units. 5 GiB = 5,242,880 KiB in binary units.
How do I convert KB to GB by hand?
Divide by 1,000,000 for decimal gigabytes, or by 1,048,576 for gibibytes. Equivalently, divide by 1,000 twice (or 1,024 twice).
Does this converter upload my numbers?
No. The conversion runs in your browser with exact integer arithmetic, so nothing you type leaves the page.
