This height converter switches between centimetres (cm) and UK feet/inches (ft/in). Enter either format and the calculator converts to the other so you can compare medical forms, fitness plans, or personal records.
It provides a quick conversion without manual calculations.
How the formula works
We use standard conversions: 1 inch equals 2.54 cm, and 1 foot equals 12 inches. We convert your input into a base unit, then format it for the other system.
Results are rounded to keep output readable, so tiny differences can occur when converting back and forth.
Worked example
Example: 175 cm converts to about 5 ft 9 in. Entering 5 ft 9 in gives roughly 175 cm.
Slight rounding differences are normal.
Common mistakes
- Entering inches in the feet field.
- Leaving both cm and ft/in blank.
- Using decimal feet instead of inches.
- Expecting a perfect round-trip after rounding.
