MB to KB
One megabyte is 1,000 kilobytes. This MB to KB page has the formula, a conversion table, three worked examples and answers to common questions.
Did this tool work for you?
What one megabyte is worth in kilobytes
This page converts megabytes (MB) to kilobytes (KB). In the converter's unit table, one megabyte equals 1,000 kilobytes, so every result here comes from a single multiplication by 1,000.
Reading the formula backwards gives MB = KB ÷ 1,000. Dividing by 1,000 undoes the multiplication, and 1 KB equals 0.001 MB.
Megabytes to kilobytes reference table
The table below lists 12 amounts of megabytes next to the matching kilobytes. The amounts were picked to suit a ratio of 1,000, so the results stay easy to read.
| Megabytes (MB) | Kilobytes (KB) |
|---|---|
| 0.01 | 10 |
| 0.05 | 50 |
| 0.1 | 100 |
| 0.25 | 250 |
| 0.5 | 500 |
| 1 | 1,000 |
| 2 | 2,000 |
| 5 | 5,000 |
| 10 | 10,000 |
| 25 | 25,000 |
| 50 | 50,000 |
| 100 | 100,000 |
Every row comes from the same function as the widget and keeps its rounding, so a figure copied from this table matches what the converter returns for that input.
Examples: turning megabytes into kilobytes
Suppose a quantity is 0.015 megabytes. Scaling it by 1,000 gives 15 kilobytes.
Example 2. For a different size, 0.12 MB, the result is 120 KB. Dividing 120 by 1,000 gets you back to about 0.12.
For the last case, begin with 95,000 kilobytes. Multiplying by 0.001 gives 95 megabytes.
Going from kilobytes to megabytes
A dedicated page covers the opposite direction: KB to MB. In that case 1 KB = 0.001 MB.
Units outside this pair can be selected in the main Data Storage Converter, which uses the same unit table.

Frequently asked questions
How many kilobytes are in one megabyte?
Each megabyte corresponds to 1,000 kilobytes, which means 10,000 kilobytes for 10 megabytes and 100,000 kilobytes for 100 megabytes.
One kilobyte equals how many megabytes?
There are 0.001 megabytes in one kilobyte. That is the inverse of 1,000, and 10 kilobytes come to 0.01 megabytes.
What does 0.055 MB come to in KB?
The result is 55 KB. The widget scales the MB figure by 1,000 and trims the digits shown.
What precision does the MB to KB result use?
Yes, the displayed KB value is trimmed. The converter prints at most 10 significant digits at or above 1, at most 8 below 1, and at most 6 decimals from 1,000 up, using exponent notation for extreme sizes. Two samples from this pair: 0.123456789 MB becomes 123.456789 KB, and 1,234.5678 MB becomes 1,234,567.8 KB.
How does the widget get from megabytes to kilobytes?
Every unit in this converter stores a factor relative to one shared reference unit. The widget multiplies the input by the factor of megabytes, then divides by the factor of kilobytes; for this pair that nets out to 1,000.
Can this converter go from KB to MB too?
Yes. The page titled "KB to MB" covers it, or you can press the swap button in the widget above. The arithmetic is KB × 0.001, so 25 KB is 0.025 MB.
