How the GB to MB Converter works

The GB to MB Converter works on Value to convert, From unit, To unit and shows the result as you type. The same input always gives the same answer — refresh the page and you will see exactly the same figure.

Formula used

value in target unit = value in source unit × (source factor ÷ target factor)

Every unit is first converted to a common base, then to the target unit, so accuracy stays intact no matter which pair you pick. For temperature the conversion uses offsets rather than plain multiplication.

Inputs used: Value to convert, From unit, To unit.
