Method, worked explanation & limitations
  1. 1 inch = 2.54 cm exactly; 1 foot = 12 inches. Feet are entered as whole feet; decimal inches are allowed and inches over twelve are normalized.
  2. Calculations retain the entered measurement precision; feet/inches display rounds to four decimal inches before carrying into feet.
  3. No population percentile, age/sex ranking or adult-height prediction is inferred. The percentage comparison uses height A as its explicit denominator.

Frequently asked questions

What exact conversion definitions are used?

One inch is exactly 2.54 centimeters and one foot is exactly twelve inches. The calculator uses these definitions to provide total inches, centimeters, meters and readable feet/inches.

Can I enter decimal inches or more than twelve inches?

Yes. Feet are whole numbers and inches may include decimals. Extra inches are normalized into feet, so 5 feet 14 inches is shown as 6 feet 2 inches.

What does the difference mode report?

It reports the absolute difference as the primary answer and a separately labeled signed A-minus-B difference. The taller/shorter indication explicitly identifies the applicable height.

What is the reference for percentage difference?

The relative comparison uses (height B minus height A) divided by height A. Height A is the named reference; a zero reference height makes that percentage undefined rather than silently zero.

How is readable feet/inches rounding handled?

Total inches are rounded to four decimal places before separating feet and remaining inches. This carries a rounded twelve-inch remainder into the feet component instead of showing a misleading 12-inch remainder.

Does this estimate percentiles or future adult height?

No. It focuses on human-height conversion, comparison and readable differences. It does not infer population percentiles, age/sex rankings or a child’s eventual adult height.
