Easily convert between kb and mb, gb, tb and vice versa in Excel

Author: Xiaoyang Last Modified: 2024-07-19

In data management and reporting, converting between different units of digital storage such as kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB) is a common task. Whether you need to transform a list of file sizes from KB to MB or vice versa, accurate conversions are crucial for clear data analysis and presentation. This guide provides two effective methods to perform these conversions in Excel.

Convert between kb and mb, gb, tb and vice versa with formulas

The following conversion formulas can help converting between kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB) assuming that 1 KB equals 1024 bytes, which is the standard in computing based on binary multiples. Here's a breakdown:

KB to MB:
To convert kilobytes to megabytes, you divide by 1024.
=A2 / 1024
MB to KB:
To convert megabytes to kilobytes, you multiply by 1024.
=A2 * 1024
KB to GB:
To convert kilobytes to gigabytes, you divide by 1024^2 (1024 KB in a MB and 1024 MB in a GB).
=A2 / 1024^2
GB to KB:
To convert gigabytes to kilobytes, you multiply by 1024^2 (1024 KB in a MB and 1024 MB in a GB).
=A2 * 1024^2
KB to TB:
To convert kilobytes to terabytes, you divide by 1024^3 (1024 KB in a MB, 1024 MB in a GB, and 1024 GB in a TB).
=A2 / 1024^3
TB to KB:
To convert terabytes to kilobytes, you multiply by 1024^3 (1024 KB in a MB, 1024 MB in a GB, and 1024 GB in a TB).
=A2 * 1024^3
How to Use These Formulas in Excel:

Suppose you have a list of number of kilobytes (KB) in range A2:A7 and you want to find out how many megabytes (MB) that is, you would use the above first formula as follows.

Select a blank cell, such as C2, enter the following formula and press Enter. Select this formula cell, drag it Fill Handle down to get the rest of the results.

=A2 / 1024

Notes:
  • Conversely, if you have the number of megabytes (MB) in cell A2 and you want to convert this to kilobytes (KB), you would use the second formula =A2 * 1024.
  • This conversion is based on the binary measurement used in computing, which is different from the decimal system used in everyday measurements where 1,000 units make up a single unit of the next higher measurement (like meters to kilometers). In digital storage, 1,024 units (bytes, kilobytes, etc.) make up a single unit of the next higher measurement due to the base-2 system used in computing.
