Megabytes to gigabytes: the relationship and formula
The unit table behind the converter relates megabytes and gigabytes through one ratio, and that ratio works out to 0.001. In other words, 1 MB = 0.001 GB.
Reading the formula backwards gives MB = GB ÷ 0.001. Dividing by 0.001 undoes the multiplication, and 1 GB equals 1,000 MB.
Megabytes to gigabytes reference table
The table below lists 12 amounts of megabytes next to the matching gigabytes. The amounts were picked to suit a ratio of 0.001, so the results stay easy to read.
| Megabytes (MB) | Gigabytes (GB) |
|---|---|
| 5 | 0.005 |
| 15 | 0.015 |
| 35 | 0.035 |
| 70 | 0.07 |
| 140 | 0.14 |
| 420 | 0.42 |
| 850 | 0.85 |
| 1,700 | 1.7 |
| 3,400 | 3.4 |
| 7,000 | 7 |
| 18,000 | 18 |
| 60,000 | 60 |
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 gigabytes
Example 1. Start with 15,000 MB. Multiply 15,000 by 0.001 and the converter shows 15 GB.
Next, 120,000 MB: the converter shows 120 GB. Because the ratio is fixed, the GB figure is 0.001 times the MB figure.
Finally, convert 0.095 gigabytes to megabytes: dividing by 0.001 gives 95.
Going from gigabytes to megabytes
A dedicated page covers the opposite direction: GB to MB. In that case 1 GB = 1,000 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 gigabytes are in one megabyte?
Each megabyte corresponds to 0.001 gigabytes, which means 0.01 gigabytes for 10 megabytes and 0.1 gigabytes for 100 megabytes.
One gigabyte equals how many megabytes?
One gigabyte equals 1,000 megabytes. Ten gigabytes equal 10,000 megabytes.
What does 55,000 MB come to in GB?
The result is 55 GB. The widget scales the MB figure by 0.001 and trims the digits shown.
What precision does the MB to GB result use?
Yes, the displayed GB 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 0.00012345679 GB, and 1,234.5678 MB becomes 1.2345678 GB.
How does the widget get from megabytes to gigabytes?
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 gigabytes; for this pair that nets out to 0.001.
Can this converter go from GB to MB too?
Yes. The page titled "GB to MB" covers it, or you can press the swap button in the widget above. The arithmetic is GB × 1,000, so 25 GB is 25,000 MB.
