How to use it
- Type the value in the kilobytes box.
- Read the result in megabytes as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
MB = kB × 0.001
Multiply the value in kilobytes by 0.001 to get megabytes.
Example
To convert 25 kB to megabytes: 25 × 0.001 = 0.025 MB.

| 10 | 0.01 |
| 20 | 0.02 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |

About the units
- Kilobyte
- A decimal (SI prefix) unit equal to exactly 1000 bytes. Not the same as the binary kibibyte, which is 1024 bytes.
- Megabyte
- A decimal unit equal to exactly 1,000,000 bytes (10^6), different from the binary mebibyte of 1,048,576 bytes.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many megabytes are in one kilobyte?
1 kB = 0.001 MB exactly.
How do I convert kilobytes to megabytes?
Use MB = kB × 0.001. For example, 25 kB = 0.025 MB.
How many kilobytes are in one megabyte?
1 MB = 1,000 kB.
Why does a 1 TB drive show about 931 GB on my computer?
Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.
What is the difference between a kilobyte and a kibibyte?
A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
