How our Gigabytes to Megabytes unit converter works

To ensure maximum accuracy when converting Gigabytes to Megabytes, our calculator uses a scientific pivot method. Instead of relying on a potentially inaccurate direct conversion, the system first converts GB into the base unit of the International System (the base unit), then recalculates the result into MB. This approach drastically reduces rounding errors.
