About Megabytes to Kilobytes Converter
This converter turns megabytes into kilobytes. One megabyte is 1000 kilobytes. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
To convert by hand, multiply the number of megabytes by 1000. For example, 10 MB × 1000 = 10,000 KB. To go back, multiply kilobytes by 0.001.
One megabyte is 1,000,000 B. A byte is 8 bits. KB, MB, GB and TB use the SI meaning (1,000 per step), while KiB, MiB, GiB and TiB use powers of 1,024.

Megabytes to kilobytes formula
To convert megabytes to kilobytes, multiply the value by 1000.
To go the other way, multiply kilobytes by 0.001, which is the same as dividing by 1000.
KB = MB × 1000Worked examples
10 MB gives 10,000 KB
10 × 1000 = 10,000
1,000 MB gives 1,000,000 KB
1,000 × 1000 = 1,000,000
4,096 MB gives 4,096,000 KB
4,096 × 1000 = 4,096,000

Good to know
MB or MiB, GB or GiB?
KB, MB, GB and TB use the SI prefixes, so each step is 1,000. KiB, MiB, GiB and TiB use powers of 1,024. This page converts the units in its title using the SI meaning.
The difference grows with size: 1 GiB is 1.07374 GB, and 1 TiB is 1.09951 TB. If a tool shows 1,024-based sizes but calls them GB, pick the GiB or MiB units in the converter to match it.
Privacy: how it works
- Every conversion is calculated by code running in your browser tab. The values you type are never sent to Ulkaa or anyone else, and nothing is stored.
- There is no account and no sign-up for this tool, and it costs nothing to use.
Tips
- Use the swap button instead of retyping when you need the reverse conversion.
- For a quick mental check, round the factor: 1 inch is about 2.5 cm, 1 kg is about 2.2 lbs, 1 mile is about 1.6 km.
- Set Precision to 2 decimals for cooking, shopping and travel, and to 6 or more for engineering work.
- Check whether a figure uses US or imperial units before converting volumes, gallons and miles per gallon.
- For land, convert for a rough size, then confirm the area from the deed or survey record.
