About the prefixes converter
This converter handles 21 prefixes units. Enter a value in either field and the other updates instantly — there is no button to press and nothing to submit. Use the swap control to reverse the direction of the conversion.
All factors are stored against a single base unit
(
none) and applied in one step, so converting A → B
never accumulates rounding error from an intermediate hop.Quick reference table
