📏 Height Calculator
Height lives in two measurement worlds — feet and inches in some countries, centimeters in most others. Enter your height in either system and this calculator shows the exact equivalent in the other, down to a tenth of a unit.
The conversion uses the exact definition of the inch (2.54 cm), so results match official conversion tables with no rounding drift.

- Choose Feet + inches or Centimeters in the Convert from menu.

Frequently asked questions
What does the Height Calculator convert?
It converts a height between the imperial system (feet and inches) and the metric system (centimeters and meters). Whichever side you enter, you get all three readouts: centimeters, meters, and feet plus inches.
What conversion factor is used?
One inch is defined as exactly 2.54 centimeters, and the calculator uses that exact factor, so 5 feet 10 inches becomes 177.8 cm with no rounding drift.
Can you give a worked example?
Enter 5 feet 10 inches and you get 177.8 cm and 1.778 m. Enter 180 cm going the other way and you get 5 feet 10.9 inches.
How precise are the results?
Centimeters are shown to one decimal place and meters to three, which is more precision than a tape measure gives. The math itself is exact.
