The short answer: 56 inches comes to 142.24 cm. That is 56 multiplied by 2.54, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 142.24 cm — 1.422 m — a BMI of 18.5 to 25, the band the WHO calls healthy, runs from 37.4 to 50.6 kg (82.5 to 112 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 2.24 cm past 140 cm, so if you need a round figure to quote, 140 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 56 that shortcut gives 140 centimeters, off by 2.24 centimeters or about 1.57%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
Height is written in feet and inches across the US and the UK and in centimetres nearly everywhere else, which is why this conversion turns up on visa applications, medical intake forms and team rosters rather than in engineering.
The formula
56 in- The quantity being converted
2.54- Exact centimeters in one inch
142.24 cm- The converted result
How it works, step by step
- Start with 56 inches.
- Apply the defined factor: one inch is 2.54 centimeters, so multiply by that.
- Result: 142.24 centimeters.
- Going the other way, divide rather than multiply — 142.24 cm ÷ 2.54 brings you back to 56 in.

Checking it backwards
Divide the answer back: 142.24 cm ÷ 2.54 returns 56 in. If a converter fails this test it has inverted the factor, which is the single most common conversion error there is.
