TB = MB × 1e-6
Both units are defined exactly, so the precision of the MB to TB result depends only on the number of decimal places you choose.
METHOD AND SOURCES
Where the conversion factors come from
Results are calculated from the unit definitions stored in the converter, not copied from a lookup table. For exact units, every value in the table follows from the same factor shown in the formula above.
