The short answer: 64 inches comes to 162.56 cm. That is 64 multiplied by 2.54, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 162.56 cm — 1.626 m — a BMI of 18.5 to 25, the band the WHO calls healthy, runs from 48.9 to 66.1 kg (108 to 146 lb). BMI is weight in kilograms divided by height in metres squared, so those figures come straight from the height on this page rather than from a chart.
The result sits 2.56 cm past 160 cm, so if you need a round figure to quote, 160 cm is the honest nearest one. Plenty of people do this in their head: multiply by 2.5 instead of using the exact factor 2.54. At 64 that shortcut gives 160 centimeters, off by 2.56 centimeters or about 1.57%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
This is a paperwork conversion more than a technical one: driving licences, sports profiles and hospital records all record height, and they do not agree on the unit.
