Question 1

What is the difference between KB and KiB?

Accepted Answer

KB (kilobyte) = 1,000 bytes (SI decimal prefix), while KiB (kibibyte) = 1,024 bytes (binary prefix). Storage manufacturers typically use KB, but operating systems often display file sizes in KiB. Both are valid — the difference is the base.

Question 2

How many MB in a GB?

Accepted Answer

Using SI (decimal) units: 1 GB = 1,000 MB. Using binary units: 1 GiB = 1,024 MiB. Our converter supports both, so you can pick the system that matches your use case.

Question 3

How do I convert KB to MB?

Accepted Answer

Type the value in the input field, select KB as the input unit and MB as the output unit. The conversion happens in real time as you type.

Question 4

Are conversions accurate for large values?

Accepted Answer

Yes. We use arbitrary precision internally through string-based conversion, so values up to petabytes and beyond are calculated exactly without floating-point drift.
