How our Grams to Kilograms unit converter works

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