1 unit equals
Exact where it matters
Conversions use the exact international definitions — one pound is exactly 0.45359237 kg, one inch exactly 2.54 cm, one mile exactly 1,609.344 m. Data sizes include both decimal (kB, MB, GB) and binary (KiB, MiB, GiB) units, since “a gigabyte” means different things to drive makers and operating systems. Both fields are editable: type in either side to convert in that direction.
